1N991B Overview

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 available with an internal-metallurgical-bond option by adding a “-1” suffix as well as RoHS pliant by adding an “e3”...
