Littelfuse Unveils SZSMF4L Automotive Grade 400-Watt TVS Diodes in Surface Mount Package

August 4, 2023

Littelfuse, Inc. (NASDAQ: LFUS), an industrial technology manufacturing company empowering a sustainable, connected, and safer world, announced the release of its new 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 ideally 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.

 

“With the megatrend of vehicle electrification and autonomous driving, TVS diode miniaturization is becoming more critical to automotive electronics engineers and PCB designers,” said Charlie Cai, Director Product Marketing SBU, Littelfuse. “The automotive grade SZSMF4L TVS diodes offer greater flexibility and space-savings, providing the ideal 400-watt solution in a small (SOD-123FL) TVS di
