DESCRIPTION

APPEARANCE

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.
