Littelfuse Unveils SZSMF4L Automotive Grade 400-Watt TVS Diodes in Surface Mount Package Suitable for Automotive Applications
CHICAGO, August 4, 2023 -- Littelfuse, 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 Inverter
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 of 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 diode package with both uni- and bi-directional 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 78V) and bi-directional (10 to 78V).
Low Leakage Current performance.
High operating temperature: up to 175℃.
