Anyone know more about analogue electronics than I do know if measuring the same resistance and voltage drop (diode test) in either direction accross the gate and cathode of an SCR ok?

@crashtestdev does it have a shunt resistor across it? what are you getting? If its the removed part, thats not good.

@crashtestdev (not an expert) but I think I’d expect two junction drops from anode to cathode and one from gate to cathode?

@RueNahcMohr No resistor, 0.1v drop measured in both directions, and tested removed out of circuit
(edit: thank you for helping!)

@crashtestdev I'm sorry, thats not a semiconductor anymore

@crashtestdev @ret Yeah 0.1V seems too low for any kind of unpowered silicon gate. I’d say that’s blown.

@crashtestdev would you like any help finding a replacement?
