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. 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 similar to JAN, JANTX, JANTXV, and JANS also exist by using MQ, MX,
MV or MSP respectively for part number prefixes and high reliability screening in
accordance with MIL-PRF-19500/507.

FEATURES
•
•
•
•
Working Standoff Voltages: 5.5 volts to 171 volts
Metallurgically bonded
Reliability data per JESD22-A108, JESD22-A104,
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)
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.
