1N6469 thru 1N6476
Voidless-Hermetically-Sealed Unidirectional
Transient Suppressors
SCOTTSDALE DIVISION
DESCRIPTION
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
and voltage ratings in both through-hole and surface-mount packages.
