Re: Transistor or diode?
I can't find the exact part but on another site it seems to be a IRFML8244TRLast edited by R_J; 04-11-2022, 01:54 PM.

Hello and happy new year ,
my Analog Combustion Machine Honeywell gone bad and I don't know what type of diode is utilized.
There is no mark around the body of the diode. The Schematics are general referred only, without any electronics components and values.
The two contacts (2),(5) of the Relay Coil need 48 Volts DC to begin operating. Between these two contacts in series is the bad diode and near of contact (5) is the bad pnp (bc856b) Transistor that can be easily replaced.
I have made a diagram of the PCB and some measurements along some... -
Hi:
I have what it might seem a zener diode. It's marked as E57, but I haven't found any reference that might match my observations.
I've took one from the same circuit and tested isolated with the power supply and a 1k resistor. with 10V, the possible zener stays at 6.6V.
It seems a SOD123 package. It measures (2.6mm x 1.6 mm).
Any idea? it's a 6.6V zener?

I have DRUCK UPS-III-IS Loop Calibrator to repair, and I found one faulty diode (O.L. both ways, even out of the circuit). The SMD code on it is E27 NMC. by ON Semi. I can't find anywhere on the internet what kind of diode it is. Being the calibrator, all elements may be crucial, to be exact, so I really don't want to mess up with any diode there. Especially if it needs to be Shottky or a particular Zener. It is connected between a Poly capacitor and in series with another (different) diode (MX47A) - pictures attached.... -
I need to find a replacement for this diode on one of the six gate drivers of a full-bridge IGBT inverter for a servo motor. It has S3 on the package. How can I find out for sure the right diode that I need. I believe it is schottky because it has 0.2V drop across.
The anode is on pin Ve and cathode on pin DESAT on 316J gate driver IC. Also would be nice if anyone had an idea of the purpose it is serving as it is not included in the suggested schematic of the 316J datasheet.
I have also drawn a partial schematic of the gate driver in this servo amplifier to try... -
smd diode marked M7 on top and below K3 pls advise the equivalent. thank you
