Description
General part information
1N4471US-Zener-Diode Series
This 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 void-less glass construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 200 volts in standard 5% tolerance. 1% and 2% tolerance versions are also available. Microchip also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.
