Hi, Is there a transistor equivalent of BFR90 ?
Hello, I would like to build this PSU because I like discrete. I am looking for a transistor equivalent for the 40411 If you can suggest similar circuits with newer transistors please let me know as well.
bfw92a ia used as a power transistor at vhf so replace with 2n2222 or better.... 2n3555
Hi, i'm designing a NIMH battery charger with Ds2711 that requires a pnp low saturation transistor, FCX718. I can't find this where I live. Anyone know an equivalent for this transistor? Tried google but didn't help much. The datasheet for this transistor is here: Tkx
equivalent needed! I want to know the equivalent of BC638 transistor & equivalent of OP-37 (I.C.)!!!!
Hi all, A model of common-emitter transconductance stage is shown as transistor_equivalent_Circuit.jpg. Who can tell me what Cb is? Some paper describe Cb as base-charging capacitor, and it is linearly proportional to the collector current Ic and the forward transit time(TF) of transistor. Could you explain this problem for me in (...)
ok for bc 808 but i can'd find BD136 SMD only pth. can i use BCP54 instead of BD136?? i'd like to find a general guide to convert pth transistor into smd. for example how can i change BC547??
I need bc 328 smd and bc 338 smd . Which is the equivalent BC 807, BC 817, BC 846, BC 847, BC 848, BC856
Hello, is there any equivalent for RCA 40242 transistor? Any suggestions?
hello I need an equivalent of this old transistor please 2n3607 equivalent.
hello, Is there any equivalent to the old BF183 or BF200 transistors? Noise figure and gain are the important factors since this is for an rx preamplifier
use any power transistor and made the correct biasing .
Any transistor can use (in the same category ) but the biasing of the circuits will be change .
Hi. I wanna know about each case MOSFET equivalent circuit when mosfet is in ON and OFF. what is different each case? Thank you.

Does anyone point to me who has to absorb RCA? I have need of to replace a transistor 17556 with one equivalent. Best Regard.
Hi all, I have a Hitron car Amplifier named "MCKinley 2-Channel 2x100W RMS". One of the amp-transistors burned and killed also one of the pre-amp transistors. I putted in a new amp-transistor, but I cannot find out what kind of transistor is used in the pre-amp. There are only the letters "C1027" on the (...)
Hi after replacing the 2SD1880 horizontal deflection transistor with one ST2310DHI (equivalent one), the transistor dies just after replacent (BCE becomes short circuit). Any suggestion on what could be the reason? Thanks a lot. Mazz
AC equivalent circuit is used in ac analysis. For example, the MOS transistor is not linear, if we want to analyze it, we must use linear equivalent circuit . But the dc equivalent circuit and ac equivalent circuit of MOS transistor are not same. So we use them in different analysis.
What application will you be working with the transistor because BC557 and ZTX500 are general purpose transistors? Please specify at least frequency or hFE desired.
What is the name of transistor?
3N201 =MFE201(Dual Gate Mosfet transistor )
Wants datasheet for transistor 2T7637B (russian transistor) what the equivalent circuit ?? Thanks

Hi, i need some help calculation the transistor bias point by hand as i do not know if i can replace the 2 resistors R1 and R2 by the thevenin equivalent, Vth=((5v*2)*1.6k)/(1.6k+1.2))=5.7v and equivalent resistance R1//R2=685Ω, like we do when the supply is normally to GND. The doubt is if is still valid when the supply is symetrical. (...)
Hi For a model of an NPN transistor you can take a look at "Microwave transistor Amplifiers" by Guillamo Gonzalez. There is a litte description of transistors and there parameters. Regards
The cutoff frequency f_t for a transistor should be given in its datasheet. This frequency determines the frequency response of the transistor parameters like the current gain β for a BJT. Are you asking for the corner frequency of the circuit surrounding it? I think a circuit diagram is in order here -- you have not mentioned
You may compare the following transistors: BLW96 ( ) 2SC2782 BLW77 BLV33 .. Regards, IanP

can any one suggest me equivalent of these these are not avliable in my city. Si9410DY MTD20N03HDL ZTX694B Would you please suggest me a link to ebook or pdf of transistor and FET equivalents
hello, im a electronics engineering student from philippines.. i need help with my homework... i need to know where to get a design/schematics/website for a full adder ic... from logic gate to transistor equivalent to "stick diagram" to ic mask layers please... thankyou very much
I think in state of the art technologies it is very hard to find a circuit model that explains the MOSFET behavior perfectly due to short channel effects and many other effects that appear as the transistor size becomes smaller and smaller,so i think u have to design according to traditional models and then use simulators to predict the real behavi
A very good place as far as datasheets are concerned is .. Here are relevant data sheets: Try the following BJTs: BFS17, BFQ57, BFQ58, BFQ10/71/72/76/77, MMBR536/571/941/951 ..

I've been trying to find the small signal equivalent model for the cascode BJT amplifier circuit below, however I don't think I am getting the right model, I can find the model for one transistor, but don't know how to find it for cascode transistors. Anyone can tell me how the small signal model for this circuit should look like ? (...)
passive load are load like resistor and diode connected transistor are active load
1. The input impedance of a MOS transistor is near infinity near DC. As you go up in frequency it looks like a capacitor. Going further up there is a real part. 2. In your simulator (or in your breadboard use a current probe) take the ratio of the gate AC voltage to the gate AC current.
Folks, have got a very simple yet very difficult question. How do I identify (accurately) the threshold voltage of a small-scale (l=180nm, w=100um) NMOS transistor from DC simulation? We all know that the threshold voltage is the voltage which if Vgs was higher than, current will start following in the channel and the transistor will be consider
please help me IGPT transistor CT60AM this is a IGPT transistor i found in Electrical circuit in Markteck machine ( racers machine) ididnt found this kind of transistors at my town and iam thinking about replacement is theres any way to replace IGPT by regular transistor or regular mosfet i tried IRFP450 but (...)
Use the following command: report_area It generally gives the value as defined in the liberty file given by the standard cell library vendor. Typical units are gate count, square micron,transistor equivalent.
Hi guys, I have a serious problem with identifiing a transistor. On the back side of this transistor was written 95A/521. And you would really help me if you can something tell me about how it works. I found it in joystick block of bager and it is highly probable that something's wrong with this part. pls help
just apply and input current and then measure the ratio: vds/id,for a particular size of your transistor. In eldo this is a simple script in measures. In cadence you may need to use skill amarnath

Hello I'm working on PA and have problem with bipolar transistor modeling . Does anybody have experiance modeling spice model in Microwave Office? I have uploaded equivalent circuit of transistor and my MWO file ( MWO 2006 v7.05 If you need, I can upload this version of MWO). I think a problem with correct connection or properties of (...)
Hi you can use BC109C, BC209C, BC549C or BC550C (the last, the best). In the american family, the 2N5818 is a good and easy choice. i think the "BC549" is the best choice. thnx This picture compares some specifications of
