Voidless Hermetically Sealed Unidirectional

Transient Voltage Suppressors

Qualified per MIL-PRF-19500/551

Qualified Levels:

JAN, JANTX, and

JANTXV

DESCRIPTION

This surface mount series of 500 watt voidless hermetically sealed unidirectional Transient

Voltage Suppressors (TVS) are military qualified to MIL-PRF-19500/551 and are ideal for

high-reliability applications where a failure cannot be tolerated. Working peak “standoff”

voltages are available from 5.0 to 51.6 volts. They are very robust, using a hard glass casing

and internal Category 1 metallurgical bonds.

These devices are also available in axial-leaded

packages for thru-hole mounting.
