If the T8436 is a date code (which seems likely), then that part was made 20
years ago.  Not surprising that they don't have a current data sheet for it.
You need to hunt down some old Motorola Power Semi databooks from the 80's.
I don't think Moto-SPS or even On-Semi makes power diodes anymore.


however, assuming that it's a 1N2264 (seems reasonable?)  I came up with:
http://www.chipdocs-dot-com/pndecoder/datasheets/MSEMI/1N2264.html
which shows it's in a DO-4 package (which looks like your picture)

I found a datasheet at Microsemi:
http://www.microsemi-dot-com/catalog/part.asp?id=1563
It's a 1200V, 10A part. Here's the pdf datasheet:
http://www.microsemi-dot-com/datasheets/COE-9.PDF

It's a pretty old part (considering that it's lower numbered than, say,
1n400x or 1n540x, which are, in themselves, pretty old parts).

I'm surprised that someone still makes it.  There are lots of better parts
that would be a drop-in replacement (unless you were depending on some
peculiarity in the diode.. maybe it's hideously slow recovery time or fairly
high Vf?)
