Description
These 0.5 W zener diodes are electrically equivalent
to the 1N957B
-
1N986B series diodes. They are
compatible with all wire bonding and die attach
techniques with the exception of solder reflow.
These diodes are available in JANHC and JANKC
per MIL-PRF-19500/117.

1. Zener voltage range equals nominal voltage ±5% for “B” suffix. “A suffix denotes ±10%, No suffix denotes ±20%, “C” suffix = ±2% and “D”
suffix = ±1%. Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
2. Zener impedance is derived by superimposing on I
ZT
at 60 HZ RMS AC current equal to 10% of I
ZT
