by calling it N channel do you mean its basically a IGBT equivalent of a npn bipolar transistor, except that instead of a gate that conducts it has a isolated mosfet like gate(whatever the IGBT inner structure was) ?
You'll also get differences between npn or PNP types because each type has different area and bulk resistance. A transistor temperature sensor can't be expected to have 0.5 K accuracy without calibration.
Hello. I'm having difficulties deducing which addition of what type of transistor is the best option for me while enabling a variable linear regulator to use its max 50mA output to be used as a max 5A output. Here are two examples I know of, the npn darlington is the one I went with first and have it on a prototype in (...)
Some of these transistors are npn, some PNP type, they have different voltage and current rating and probably different switching speed.
Can anyone knows 1558B npn transistor datasheet?
hi. i want simulate a oscillator circuit with NEC2sc3358 transistor in ADS,but i don't have nonlinear model (parasitic internal capacitances and inductances) of it.can anyone help me?it has a datasheet in internet that only have voltage and current characteristics...:-( or what transistor work likely NEC 2sc3358?
This is an RF amplifier transistor. Following is the short datasheet of the same. You can use any Silicone RF (npn) transistor in its place. 77183 PN5179 or 2N5179 are the same type of transistor.
I'm not sure, but I think those are sensors that use a Bipolar junction transistor... Probably they trigger a logic signal... I think the sensor sensing part should be connected to the base o a transistor npn or PNP... And they are probably used as normal transistors [table="
Your IC shows no ground connection. Don't know if it is implied. In any case the bias current goes into the npn transistor, then that current needs to have a path to ground. This is chancey, seeing the components being in the emitter leg. Consider putting the converter assembly in the collector leg. Or you might substitute a PNP type instead.
EDIT: To make the story short: When I use a transistor to open and close a switch, I can't just leave the collector hanging, right? And I shouldn't ground it nor the emittor, right? What I need is a big resistor between emittor and collector, which is short circuited when the base gets high. Am I onto it here? BACKGROUND I've s
as i would need to apply current to pnp transistor's base even if the motor is off There would be no power consumption in off state. You only need an additional low power npn transistor to switch the base current to the PNP transistor.
You can use npn transistor working as a switch and driven by 1.5V from the igniter .. See attached picture .. The type of transistor will depend on the current required to drive the fan .. Connect the fan to a 9V battery and measure the current .. Then, select a transistor that has I at leaset twice as (...)
The basic filter design is near to a 2nd order butterworth filter, but by combining high- and low-pass to operate with a single buffer amplifier, the filter characteristic will be sligtly modified. The transistor type doesn't matter much, the circuit can work with any AF silicon npn.
Hi, I am looking for some IC which can work as high side switch with maximum supply voltage of 12V. I need the gate to control by digital signals. I can use a P-type FET along with a pull up resistor at gate and npn transistor from gate to ground, but wondering if some dedicated chips is availalalbe in market having all the features in (...)
Shouldn´t T1 be a npn and not PNP transistor as posted?
There's no BC558 npn transistor. BC558 is always a PNP type. That's why you can't find it. An npn type would be for example BC548.
You may try the opposite type of transistor you are using now. Mean if you are usiing npn type, youmay change it to PNP and vice versa. It may help suggesting you something more if you post your present schematic here. Good luck
The lm317 is not a transistor , it is a voltage regulator ( ajaustable type). It would not be possible to replace this with anything other than another regulator. You would have to do a considerable amount of change to the circuit if you were going to use a transistor
Hi, Have a look at these posts * by t
Anyone can show me how to differentiate the transistor npn & PNP using Multi Tester (Analog & Digital)? And how to ensure the Base, Collector & Emitter is correct using Multi Tester (Analog & Digital)? Thanks & best regards, Keng Loong, Liew
