Littelfuse, Inc. has expanded its TPSMB Series of Automotive Transient Voltage Suppression (TVS) Diodes. The AEC-Q101 qualified TVS Diodes are designed to protect sensitive automotive circuitry from a higher level of voltage transients caused by other transient voltage events such as lightning.
The TPSMB Series Automotive TVS Diodes benefit AEC-Q101 qualified automotive-grade products that are well-suited for high reliability applications. They also provide 600W of peak pulse power dissipation rating, which is most common for automotive applications. They offer a compact surface-mount package (DO‑214AA SMB) for the most effective use of board space. With the 7.5V to 650V breakdown voltage gamut, many automotive design requirements can be met, as well as protecting IGBT active clamping and Xenon head lamp ignitors constraints.
The expanded line of TPSMB Series TVS Diodes includes the following applications:
- IGBT active clamping in HVAC systems
- Convertor/invertor systems for electric vehicles
- Series battery protection in automotive Battery Management Systems (BMS)
- Xenon headlamp ignitors (for bidirectional parts)
- Electronic Control Units (ECUs)
- Automotive sensors
- BCMs/LIN Bus/CAN Bus
- On-board entertainment systems
“The high voltage additions to the TPSMB Series of Automotive TVS Diodes offer circuit designers a single-component alternative to using multiple TVS Diodes in series to provide higher levels of transient voltage protection,” said Charlie Cai, Littelfuse’s Global Product Manager, Electronics Business Unit. “Not only does this simplify the design of the printed circuit board but it enhances the reliability of the design.”
