Zener Diode

[gary]

Hello again Martin,

As Chuck Milton mentioned, NTE lists the replacement as just 5182A, without
the 'K' indicating reverse polarity. This started me looking and I found the
same difference in two older catalogs, NTE indicating standard polarity and
ECG indicating reverse polarity. I'm not sure which is indicating the
correct polarity but I am curious as to which one your application indicates
the 1S265 should be.

Regards,
Gary

Thanks Gary, now to find one, they are used in the TL-922.
