SMB3Z**A Series

High-Power Surface-Mount TVS Diodes for Industrial and Telecom Surge Protection

The SMB3Z**A Series TVS diodes, packaged in SMB (DO-214AA), offer up to 3W peak pulse power dissipation. Designed to clamp high-energy transient voltages, they provide superior protection against ESD, surge, and lightning-induced transients. With voltage ratings from 3.3V to 250V, fast response time, and low reverse leakage current, these diodes are ideal for power supplies, telecom base stations, and industrial control systems.

  • Telecom base stations and network equipment
  • Power supply modules and DC/DC converters
  • Industrial automation control systems
  • Smart appliances and consumer electronics
  • Automotive electronics and EV charging units
