versions
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.

FEATURES
Surface mount equivalent of JEDEC registered 1N6461 thru 1N6468 series.
Available as 500 watt peak pulse power (PPP).
Working peak “standoff” voltage (VWM) from 5.0 to 51.6 volt.
High surge current and peak pulse power provides transient voltage protection for sensitive circuits.
Triple-layer passivation.
Internal “Category 1” metallurgical bonds.
Voidless hermetically sealed glass package.
JAN, JANTX, and JANTXV qualifications available per MIL-PRF-19500/551. Other screening in
reference to MIL-PRF-19500 is also available.
(See part nomenclature for all available options.)
RoHS compliant versions available (commercial grade only).
APPLICATIONS / BENEFITS
Military and other high-reliability applications.
