The SZSMF4L series is designed to protect sensitive systems or components from high voltage, high energy transients. It offers a fast response time, low zener impedance, high surge and excellent clamping capabilities. Because of its small size, it is ideal for use in automotive electronics applications.

Features

  • Zener transient overvoltage suppressors
  • Working peak reverse voltage range 5 V to 78 V for unidirectional and 10 V to 78 V for bi-directional
  • Peak power: 400 watts @ 1 ms
  • Planar chip design with low leakage current performance
  • Response time is typically < 1 ns
  • ESD rating of class 3 (> 16 kV) per human body model
  • IEC-61000-4-2 ESD 30 kV(Air), 30 kV (Contact)
  • Lead orientation in tape: cathode lead to sprocket holes
  • These components are Pb-free and are RoHS compliant
  • SZ prefix for automotive and other applications requiring control change requirements; AEC−Q101 qualified and PPAP capable

Applications

TVS components are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Automotive applications.
