1N6461 thru 1N6468
Voidless-Hermetically-Sealed Unidirectional
Transient Suppressors
DESCRIPTION
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 âStandoffâ 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 âUSâ 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.
