Vishay Planar SMT TRANSZORB Transient Voltage Suppressors

Vishay’s TransZorb TVS SMBJ-D series is designed to protect sensitive devices against transients from secondary lightning strikes and inductive load switching. The series achieves a very tight ±3.5% breakdown voltage tolerance and low reverse leakage current to minimally impact power efficiency. The devices are rated for higher peak pulse surge currents and lower clamping voltages than previous devices for improved protection of ICs.  

The SMBJ-D series is offered with a wide range of stand-off voltages, unidirectional or bidirectional polarity, and a wide operating temperature range, allowing it to be used in applications such as consumer devices, computers, industrial, and telecom equipment. The TVS is packaged in the DO-214AA package that measures 5.4 by 3.6 by 2.3 mm, providing designers protection in a small package for compact and high-density designs.

  • Tightened breakdown voltage tolerance of ± 3.5 %
  • High peak pulse surge currents from 2.03 A to 65.9 A
  • Excellent clamping capability from 9.1 V to 301 V
  • Stand-off voltage from 5.0 V to 188 V
  • Available with unidirectional or bidirectional polarity
  • DO-214AA package (5.4 mm x 3.6 mm x 2.3 mm)
