Description
These 0.5 W zener diodes are electrically equivalent
to the 1N821
-
1N829 series diodes. All junctions are
completely protected with silicon dioxide. They are
compatible with all wire bonding and die attach
techniques with the exception of solder reflow.

1. Zener impedance is derived by superimposing on I
ZT
at 60 HZ RMS AC current equal to 10% of I
ZT
.
2. The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specialized mV at
any discrete temperature between the established limits, per JEDEC standard No.5.
