1N6469US thru 1N6476US
Voidless-Hermetically-Sealed Surface
Mount Unidirectional Transient
Suppressors
SCOTTSDALE DIVISION
DESCRIPTION
This surface mount 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 axial-leaded packages for thru-hole mounting by deleting
the “US” suffix (see separate data sheet for 1N6469 thru 1N6476A). 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.
