[SOLVED] What does the last letter in the PCR406 identification code mean for SCRs?

[Electronics123]

I'm replacing a defective SCR (TO-92). It has PCR406J printed on it. When shopping, I've noticed that there are some advertised as just PCR406, some with an S on the end and some with J. What does the suffix S or J (or none) mean?

This is usually found toward the back of the datasheet and could be a package code or a quality screening grade / temp range. It varies by mfr

It depends on manufacturer but my data sheet shows them graded by gate current so it might indicate how sensitive they are to triggering.

Hi,

often the marking on the device gives a hint on the manufacturer. Maybe a logo.
