Littelfuse introduces the SZSMF4L 400W TVS Diode Series revolutionizing automotive electronics with enhanced protection, space-saving design, and optimal performance.
Littelfuse, Inc. recently unveiled its latest product – the SZSMF4L 400 W TVS Diode Series. In the contemporary automotive world, there’s a noticeable uptick in the amount and complexity of electronic components being integrated into vehicles. With this growing sophistication in automotive electronics, there’s an ever-increasing need to ensure that these components are adequately shielded and safeguarded from potential damages caused by high voltage and high energy transient events.
The newly introduced series has been designed to protect sensitive systems or components from the potential harms of high voltage and powerful energy surges. The company says that one of its distinguishing features is its quick response time, which, combined with its low zener impedance, ensures robust surge and good clamping protection. Given its sleek and compact design, this series is well-suited for seamless integration into the intricate world of automotive electronics. Its low leakage current ensures that it stands as an optimal choice for the critical task of protecting delicate sensors.
The diodes offer the following key features and benefits:
- The package suits automated PCB assembly.
- Uses ~40% less PCB space than prior components.
- Peak reverse voltage: Uni-directional (5-78 V), bi-directional (10-78 V).
- Low Leakage Current performance.
- High operating temperature up to 175°C.
The series is suitable for various automotive electronics like EV powertrains, On Board Charging (OBC), Battery Management Systems (BMS), EV Inverter, Power Distribution Unit (PDU), Domain Controller, Zone Controller, and Body Control Module. Its low leakage current also ensures sensor protection. The company asserts that as vehicle electrification and autonomous driving become dominant trends, diode miniaturization is increasingly essential for automotive electronics engineers and PCB designers. These diodes grant enhanced flexibility and conserve space, delivering an optimal 400-watt solution in a compact package equipped with uni- and bi-directional protection.
