DESCRIPTION

This Zener Voltage Regulator series is military qualified to MIL-PRF-19500/406 and is ideal

for high-reliability applications where a failure cannot be tolerated. These industry-

recognized 1.5 Watt Zener Voltage Regulators are hermetically sealed with voidless-glass

construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 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 surface-mount packages (see separate

data sheet for 1N4460US thru 1N4496US and 1N6485US thru 1N6491US). Microsemi also

offers numerous other Zener products to meet higher and lower power ratings in both thru-

hole and surface mount packages.
