DESCRIPTION
This ZENER Voltage Regulator series is military qualified to MIL-PRF- 19500/533 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 0.5 Watt ZENER Voltage Regulators are hermetically sealed with voidless-GLASS construction using an internal metallurgical bond. It includes ZENER selections from 2.4 to 200 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. They are also available in axialleaded packages (see separate data sheet for 1N6309 thru 1N6355). Microsemi also offers numerous other ZENER products to meet higher and lower power ratings in both thru-hole and SURFACE MOUNT packages.
