These surface mount Transient Voltage Suppressors (TVSs) are used for protecting
sensitive components requiring low clamping voltage levels. They are rated at high
current impulses typically generated by inductive switching transients. They are also
optionally available as RoHS Compliant (annealed matte-Tin finish) with an e3 suffix
added to the part number. Other benefits are achieved with low-profile surface mount
J-bend or Gull-wing terminals for stress-relief and lower weight. Its low-flat profile
provides easier insertion or automatic handling benefits compared to other MELF style
packages. Options for screening to avionics grade with MA prefix or similar to JAN,
JANTX, JANTXV, and JANS by using MQ, MX, MV or MSP respectively for part
number prefixes for screening in accordance with MIL-PRF-19500/500.
