DESCRIPTION
APPEARANCE
This surface mount series of industry recognized voidless-hermetically-sealed
Unidirectional Transient Voltage Suppressor (TVS) designs is military qualified to MIL-
PRF-19500/551 and are ideal for high-reliability applications where a failure cannot be
tolerated. They provide a Working Peak “Standoff” Voltage selection from 5.0 to 51.6
Volts with 500 W ratings. They are very robust in hard-glass construction and also use
an internal metallurgical bond identified as Category I for high reliability applications.
The 500 W series is military qualified to MIL-PRF-19500/551. These devices are also
available in axial-leaded packages for thru-hole mounting by deleting the “US” suffix
(see separate data sheet for 1N6461 thru 1N6468). Microsemi also offers numerous
other TVS products to meet higher and lower peak pulse power and voltage ratings in
both through-hole and surface-mount packages.
Package “E”
(or “D-5B”)
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
APPLICATIONS / BENEFITS
High surge current and peak pulse power provides
transient voltage protection for sensitive circuits
Triple-layer passivation
Internal “Category I” metallurgical bonds
Voidless hermetically sealed glass package
JAN/TX/TXV military qualifications available per MIL-
PRF-19500/551 by adding JAN, JANTX, or JANTXV
prefix
Further options for screening in accordance with MIL-
PRF-19500 for JANS by using a “MSP” prefix, e.g.
MSP6462, MSP6468, etc.
Axial-leaded equivalents are also available in a
square-end-cap MELF configuration (see separate
data sheet for 1N6461 thru 1N6168)
