1N6461 thru 1N6468 Voidless-Hermetically-Sealed Unidirectional Transient Suppressors SCOTTSDALE DIVISION APPEARANCE This series of industry recognized voidless-hermetically-sealed Unidirectional Transient Voltage Suppressor (TVS) designs is military qualified to MIL-PRF19500/551 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 500 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 500 W series is military qualified to MIL-PRF-19500/551. These devices are also available in a surface mount MELF package configuration by adding a “US” suffix (see separate data sheet for 1N6461US thru 1N6468US). Microsemi also offers numerous other TVS products to meet higher and lower peak pulse power and voltage ratings in both through-hole and surface-mount packages. “E” Package WWW .
