Littelfuse unveils SZSMF4L automotive grade 400W TVS diodes

Littelfuse has announced the release of its SZSMF4L 400 W TVS Diode Series.

As automotive electronics continue increasing in volume and sophistication, all these components require protection from high voltage, high energy transients.

The SZSMF4L TVS Diodes protect these sensitive systems with fast response time, low Zener impedance, high surge handling, and excellent clamping capabilities. Its low leakage current is also ideal for protecting sensors. Due to its small size, it is suitable for most automotive applications, especially vehicle electrification.

 The SZSMF4L Series is suited for a range of automotive electronics applications, including:

  • EV powertrain,
  • On Board Charging (OBC),
  • Battery Management System (BMS),
  • EV Invertor,
  • Power Distribution Unit (PDU),
  • Domain Controller,
  • Zone Controller,
  • Body Control Module,
  • Low leakage current required for sensor protection.

The SZSMF4L Series SMD TVS Diodes offer the following key features and benefits:

  • Compact SOD-123FL package compatible with automated PCB assembly processes
  • Uses ~40% less printed circuit board space than previously available components
  • Working peak reverse voltage range: Uni-directional (5 to 78 V) and bi-directional (10 to 78 V)
  • Low Leakage Current performance
  • High operating temperature: up to 175°C
