JAN1N6467 Datasheet, PDF (1/3 Pages) Microsemi Corporation – Voidless-Hermetically-Sealed Unidirectional Transient Suppressors
1N6461 thru 1N6468
Voidless-Hermetically-Sealed Unidirectional
Transient Suppressors
This series of industry recognized voidless-hermetically-sealed Unidirectional
Transient Voltage Suppressor (TVS) designs is military qualified to MIL-PRF-
19500/551 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.
