TRANSIENT VOLTAGE SUPPRESSORS
SCOTTSDALE DIVISION
DESCRIPTION
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.

JESD22-A113-B, JESD22-A101-B, and JESD22-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 100%
temperature cycle -55°C to +125°C (10X), surge (3X), 24

Options for screening in accordance with MIL-PRF-
19500/500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers. For example, designate a
MXSMCJ5629A for a JANTX screen.
RoHS Compliant devices available by adding “e3” suffix
