Unidirectional Surface Mount
Transient Voltage Suppressor
TM

DESCRIPTION
SURFACE MOUNT
PACKAGE
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
prefixes respectively for part numbers and high reliability screening in
accordance with MIL-PRF-19500/500.

FEATURES
APPLICATIONS / BENEFITS
Low inductance
Reliability data per JESD22-A108, JESD22-
A104, JESD22-A113-B, JESD22-A101-B, &
JESD22-A102
Thermally efficient surface mount with J-bends
