1N6632 thru 1N6637
DESCRIPTION
APPEARANCE
T
his 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.
