DESCRIPTION
APPEARANCE
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 ar e 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 a utomatic handling benefits compare d 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.

FEATURES APPLIC ATIONS / BENE FITS
• Reliability data per JESD22-A108, JESD22-A104
JESD22-A113-B, JESD22-A101-B, and JES D22-A102
• Thermally efficient surface mount with J-bends or Gull
wings termination for stress relief (flat handling surface
and easier placement)
• Optional 100% screening for avionics grade available by
adding MA prefix to part number for added 10 0%
temperature cycle -55°C to +125°C (1 0X), surge (3X), 24
hours HTRB and post test (VBR and ID)
• Options for screening in accordance with MIL-PRF-
19500/500 for JAN, JANTX, and JANTXV are available
by adding MQ, MX, or MV prefixes respectively to part
numbers. For example, designate a MXSMCJ5629A for
a JANTX screen.
