Diode type PG1992 ?...

Anybody know where to get these or can recommend a replacement?
I can\'t even find it in my data books, so I don\'t know the specs.

It\'s in a late 1970\'s PC-100A thermal printer base for TI calculators.

I ordered some NTE 519 diodes, compatible with the PG 1992
Sealed in package... but the markings on the components are 1N4148
Apparently these are compatible too!

Well, that is about the most common diode around. Apparently it
was nothing special.
(which can be more or less expected in a device like that)

Hopefully you did not pay more than a few cents a piece plus the
shipping/handling...

 I didn\'t realize it but a 1N4148 is listed as a fast switching diode.

That begs the question, how fast? I suspect it will be fast enough

for a 1970s thermal printer base.

Reverse recovery time is 4ns \"when switched from IF = 10 mA to IR = 60
mA; RL = 100 Ω; measured at IR = 1 mA;\" Philips data sheet, 1999.
