CD957B thru CD986B
Zener Diode Chip Series
Features
• 0.5 W Capability with Proper Heat Sinking • Electrically Equivalent to 1N957B - 1N986B • All Junction Protected with Silicon Dioxide
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.
1 2. Zener impedance is derived by superimposing on IZT at 60 HZ RMS AC current equal to 10% of IZT.
