Voidless Hermetically Sealed Unidirectional
Transient Voltage Suppressors
Qualified per MIL-PRF-19500/551
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 âstandoffâ
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 âstandoffâ 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 âCategory 1â 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.
⢠Extremely robust construction.
⢠ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4 respectively.
⢠Protection from secondary effects of lightning per select levels in IEC61000-4-5.
⢠Square-end-cap terminals for easy placement.
⢠Nonsensitive to ESD per MIL-STD-750 method 1020.
⢠Inherently radiation hard as described in Microsemi âMicroNote 050â.
