As automotive electronics continue to grow in size and complexity, all of these components require protection against high-voltage, high-energy transients.
With fast response time, low Zener impedance, high surge handling and excellent clamping capability, the SZSMF4L TVS diode protects these sensitive systems. The low leakage current is also perfect for protecting sensors. It is suitable for most automotive applications due to its small size.
The SZSMF4L series is ideal for a variety of automotive electronics applications, including:
Electric Vehicle Powertrain
On-Board Charging (OBC)
Battery Management System (BMS)
Electric vehicle inverter
Power Distribution Units (PDUs)
domain controller
zone controller
Body Control Module
Low leakage current required for sensor protection
"With the megatrend of vehicle electrification and autonomous driving, miniaturization of TVS diodes is becoming increasingly important to automotive electronics engineers and PCB designers. The vehicle-grade SZSMF4L TVS diode offers greater flexibility and space savings, providing an ideal 400 watt solution in a small (SOD-123FL) TVS diode package with unidirectional and bidirectional coverage." Said Charlie Cai, SBU Director of Product Marketing, Littelfuse.
SZSMF4L Series SMD TVS Diodes have the following key features and benefits:
Packaged in a compact SOD-123FL package that is compatible with automated PCB access processes.
Occupies approximately 40% less PCB space than previously available components.
Operating Peak Reverse Voltage Range: Unidirectional (5 to 78 V) and Bidirectional (10 to 78 V).
low leakage current performance.
High operating temperature: up to 175°C.
SZSMF4L Series SMD TVS Diodes are available in tape and reel packaging. If you are interested in the electronic product, welcome to send us the BOM!
