DESCRIPTION
APPEARANCE
T
his surface mount 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 axial-leaded
packages (see separate data sheet for 1N4460 thru 1N4496 and 1N6485 thru
1N6491). Microsemi also offers numerous other Zener products to meet higher
and lower power ratings in both thru-hole and surface mount packages.
