Maximum ratings are stress ratings only. Functional operation above the recommended operating conditions is not implied. Extended exposure to stresses above the recommended operating conditions may affect component reliability. 1. 10 x 1000 µs, non−repetitive. 2. 1” square copper pad, FR−4 board. 3. FR−4 board, using Littelfuse minimum recommended footprint. 4. 1/2 sine wave (or equivalent square wave), PW = 8.3 ms, duty cycle = 4 pulses per minute maximum.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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

Key Features

  • & Benefits.
  • Automotive grade, AEC-Q101.
  • ESD protection of data lines in qualified and PPAP capable accordance with IEC 61000-4-.
  • Zener transient overvoltage 2 30 kV (Air), 30 kV (Contact) suppressors.
  • Compact design in SOD-123FL.
  • Working peak reverse voltage package range 5 V to 78 V for uni-.
  • Lead orientation in tape: directional and 10 V to 170 V cathode lead to sprocket holes for bi-directional.
  • These components are Pb-free.
  • Standard zen.
