1N6309US thru 1N6355US
VOIDLESS-HERMETICALLY-SEALED
Surface Mount 500 mW Glass Zener Diodes
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 axial-
leaded 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.
