Littelfuse, Inc., an industrial technology manufacturing company, announced the launch of the TPSMB-L Series Automotive TVS Diodes, designed explicitly for Battery Management Systems (BMS) in 800 V electric vehicles (EVs).
These advanced diodes feature an ultra-low clamping voltage (Vcl), providing superior protection for sensitive components such as Analog Front End (AFE) and Battery Management ICs (BMICs). The TPSMB-L Series addresses the growing demand for reliable, high-performance components in the fast-expanding EV market.
With a focus on safety and reliability, these diodes meet the rigorous requirements of ISO-26262, the global standard for functional safety in automotive systems, ensuring optimal performance in critical BMS applications.
Applications
- Electric vehicles (EVs): Designed for 800 V battery systems in electric and hybrid vehicles.
- Battery management systems (BMS): Ensures safety and longevity of AFEs and BMICs in 14- to 20-cell designs.
- High-voltage automotive systems: Suitable for advanced EV architectures requiring ISO-26262 compliance.
Features
- Ultra-low clamping voltage (Vcl): Ensures effective protection for AFEs and BMICs, safeguarding sensitive electronic components from voltage spikes and surges.Automotive Grade Reliability: AEC-Q101 qualified with PPAP Level 3 compliance, meeting the stringent standards of automotive applications.
- High power handling: 600 W peak pulse power capability in a compact SMB DO-214AA package.
- Wide application range: Designed for 14- to 20-cell BMS configurations, ideal for high-voltage EV battery systems.
- Fast response time: Protects against electrostatic discharge (ESD) and transient voltage surges.
“With the growing complexity and power demands of electric vehicle systems, protecting critical electronics components like AFEs and Battery Management Systems ICs is more important than ever,” said Charlie Cai, director of product management, Protection Business at Littelfuse. “By combining ultra-low clamping voltage with automotive-grade performance, the TPSMB-L Series empowers engineers to meet stringent functional safety standards like ISO-26262 while providing robust reliability.”
