SMCJ5908/SMCG5908, e3
Unidirectional Surface Mount
Transient Voltage SuppressorTM
S C O T T S D A L E D I V I S I O N
DESCRIPTION
APPEARANCE
These surface mount Transient Voltage Suppressors (TVSs) are used for protecting
sensitive components requiring low clamping voltage levels and are also available as
RoHS Compliant by adding an e3 suffix to the part number. 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.
