1N6469US

Voidless-Hermetically-Sealed Surface Mount Unidirectional Transient Suppressors

Microsemi Corporation 

SCOTTSDALE DIVISION

1N6469US thru 1N6476US

Voidless-Hermetically-Sealed Surface

Mount Unidirectional Transient

Suppressors

DESCRIPTION

APPEARANCE

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.

Package “G”

(or “D-5C”)
