C122D1 pinout?

Moto SCR C122D1?s datasheet lacks pinout:

This is the only datasheet out there that I can find.

Anyone have a databook for this one?

Thanks.

Probably that's originally a GE part number. Pin 1 cathode, pin 2 anode, pin 3 gate (and tab = anode).

Being bored, I had a go at searching - I could only find Motorola data with no pin details.

AFAIK: TO220 SCRs have an industry standard pin layout, so if you find another TO220 SCR, the sheet should give what you need.

Having said that - I vaguely remember one manufacturer making a range of SCRs with round section lead wires that probably had reversed layout.

** GE made C122 series SCRs in 0.7mm round, gold plated lead TO220 paks.

The body colour was pale blue on older examples. Same goes for triacs like the SC141 series.

But was the pin layout standard? - I vaguely remember something odd about those devices, but not what.
