These industryrecognized 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 thruhole and surface mount packages.
