However looking in the print set the diode is listed
as 1114197-00 with the
remark "60 AMP POWER SCHOTTKY DIODE"
Is the Unitrode USD5096F a 60 Amp diode? This link tells me it is a 35A
diode:
http://www.electronicsurplus.com/unitrode-usd5096f-diode-35amp-35v-piv
and so does this link:

It's possible (although unlikely) that DEC selected diodes that could stand 60A for
this location from what were
nominally 35A parts. More likely, I think, is that what is _needed_ here is a 35A diode
(what is the output current
of this PSU) and that the originially specified part was a 60A one (which is clearly be
OK). Then somebody found
a 35A part that would work.
Of course you can always fit a higher current diode than is strictly required (provide the
switching times are
fast enough in a circuit like this). My guess is that since diodes have improved since the
days of the 11/750,
you could fit modern 60A shottky diodes without problems.
