1N989B, 1N957B Datasheet - Microsemi

1N989B Silicon 500mW Zener Diodes

The popular 1N957B thru 1N992B series of 0.5 watt Zener Voltage Regulators provides a selection from 6.8 to 200 volts in standard 5% or 10% tolerances as well as tighter tolerances identified by different suffix letters on the part number. These glass axial-leaded DO-35 Zeners are also optionally av.

1N989B Features

* JEDEC registered 1N957B(-1) to 1N992B(-1) series

* Internal metallurgical bond option available by adding a “-1” suffix (similar to military product)

* Surface Mount equivalents available as MLL957B to ML
