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 “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.
• 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 “MicroNote 050”.
