Voidless Hermetically Sealed Bidirectional

Transient Voltage Suppressors

Qualified to MIL-PRF-19500/516

Qualified Levels:

JAN, JANTX, JANTXV

and JANS*

DESCRIPTION

This series of industry recognized voidless, hermetically sealed bidirectional Transient Voltage

Suppressors (TVS) are military qualified to MIL-PRF-19500/516 and are ideal for high-reliability

applications where a failure cannot be tolerated. They provide a working peak “standoff” voltage

selection from 5.7 to 152 Volts with a 1500 W rating for a 10/1000

µs pulse. They are very robust

in hard-glass construction and use internal Category 1 metallurgical bonds for high reliability.

These devices are available as both a non-suffix part and an “A” version part involving different

voltage tolerances as described in the nomenclature section. These devices are also available in a

surface mount MELF package configuration.

Also available in:

“C” SQ-MELF
