DESCRIPTION

APPEARANCE

This Zener Voltage Regulator series is military qualified to MIL-PRF-

19500/356 and is ideal for high-reliability applications where a failure

cannot be tolerated. These industry-recognized 5 Watt Zener Voltage

Regulators are hermetically sealed with voidless-glass construction using

an internal metallurgical bond. It includes Zener selections from 3.3 to 390

volts in standard 5% tolerances as well as tighter tolerances identified by

different suffix letters on the part number. They are also available in

surface-mount packages (see separate data sheet for 1N4954US thru

1N4996US, 1N5968US thru 1N5969US, and 1N6632US thru 1N6637US).

Microsemi also offers numerous other Zener products to meet higher and

lower power ratings in both thru-hole and surface mount packages.
