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 axial-leaded packages for thru hole mounting by deleting the US suffix (see separate data sheet for 1N4954 thru 1N4996, 1N5968 thru E Package 1N5969, and 1N6632 thru 1N6637). Microsemi also offers numerous other (or D-5B) Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.
