1N6469 1N6476 WWW.Microsemi .COM 1N6469 thru 1N6476 Voidless-Hermetically-Sealed Unidirectional SCOTTSDALE DIVISION Transient Suppressors DESCRIPTION APPEARANCE This series of industry recognized voidless-hermetically-sealed Unidirectional Transient Voltage Suppressor (TVS) designs is military qualified to MIL-PRF- 19500/552 and are ideal for high-reliability applications where a failure cannot be tolerated. They provide a Working Peak Standoff Voltage selection from 5.0 to 51.6 Volts with 1500 W ratings. They are very robust in hard-glass construction and also use an internal metallurgical bond identified as Category I for high reliability applications. The 1500 W series is military qualified to MIL-PRF-19500/552. These devices are also available in a surface mount MELF package configuration by adding a US suffix (see separate data sheet for 1N6469US thru 1N6476AUS). Microsemi also offers numerous other TVS products to meet higher and lower peak pulse power G Package and voltage ratings in both through-hole and surface-mount packages.
