57 Threads found on edaboard.com: Equivalent Diode
If you look at the equivalent schematic shown in the datasheet directly below the functional block diagram, you surely understand how a high reference input current can be generated - by forward biasing the Ref-Cathode (base-collector) diode. This won't happen in a typical application, e.g. the datasheet reference circuits, but can happen under ci

Presently, the diode is shorting the DC/DC output to input. You need two diodes towards 89S52, one for 3.7 and one for 5V, or equivalent electronic switches with lower voltage drop.

ferrite beads tend to be low Q and used more to reduce radiated noise transients or RF noise.
Better way is to use 100 Ohm CAT5 type transmission lines from 50~100 Ohm CMOS LOGIC ( e.g. ALVC types) and termination R @ V/2 or equivalent Thevenin circuit with Pullup/dn if you want best speed and noise immunity.

Since you have terminated the output with equivalent voltage source, the circuits becomes exactly symmetrical -->so the circuit can be folded into one tail source cascoded with Input pair (2w/l) & the nmos load as diode connected with (2w/L) -->Now caluculating gain from Vcm to output -->we will get gdst/gmn (<<<<1) [gdst-->gds of the tail transist

"Piecewise linear" means you can't determine an equivalent series resistance value at 0.7 V and assume it's still valid at 3.3 V. According to the exponential I/V characteristic, you get the tenfold current when increasing the forward voltage by 0.06 V.
No usual silicon diode will stand a forward voltage of 3.3V longer than a few microseconds.

I guess, it might be a MOC3161 (optotriac with zero crossing control) equivalent.
But if it's a phototransistor though, most have an industry standard pinout, you can refer to similar types. The LED can be easily identified with a multimeter (in diode voltage range), also the base pin of the optocoupler if connected to a pin.

Or try the equivalent of a 1A zener, made from 5 diodes in series, each with a 1A rating.
