SZ1SMBxxCA
Roll Over to Zoom

The SZ1SMB series is designed to protect voltage sensitive components from high voltage, high energy transients. They have excellent clamping capability, high surge capability, and fast response time. The SZ1SMB series is supplied in the Littelfuse exclusive, cost-effective, highly reliable package and is ideally suited for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications.

Features:

  • Zener Transient Overvoltage Suppressors
  • Peak Power − 600 W @ 1ms
  • ESD Rating of Class 3 (>16 kV) per Human Body Model
  • Response Time is Typically < 1 ns
  • Intended for UL 497B Type Protection
  • Low Profile Package
  • Pb-free means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD-609A.01)
  • SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable
