Littelfuse offers AEC-Q101-qualified TVS diode in SMB package

Higher voltage AEC-Q101-qualified TVS diodes announced by Littelfuse are optimised to protect sensitive automotive circuitry from damaging surges and electrostatic discharges. The TPSMB series of automotive TVS diodes combines up to 600W of peak pulse power dissipation with fast response, says Littelfuse.

The TPSMB series automotive TVS diode offers circuit designers a high-voltage, single-component circuit protection solution, adds the company. By eliminating the need to use multiple TVS diodes in series to provide adequate protection, the TPSMB series can simplify PCB design and improve reliability, claims Littelfuse. Standoff voltage ranges from 10 to 550V for both uni-directional and bi-directional forms, making the series suitable for the protection of I/O interfaces, Vcc bus and other vulnerable circuits.

Typical applications for TPSMB series TVS diodes include automotive electronic control units (ECUs), BCMs/LIN bus/CAN bus, automotive sensors, on-board entertainment systems, Xenon head lamp ignitors, IGBT active clamping in HVAC and converter/inverter systems and series battery protection in battery management systems.

“Both unidirectional and bidirectional AEC-Q101 qualified TPSMB Series TVS Diodes can now deliver higher voltage protection in a standard DO-214AA SMB package,” said Charlie Cai, global product manager, Electronics Business Unit at Littelfuse. “The combination of higher voltage protection and a small footprint means circuit designers don’t need to reserve additional circuit board space to accommodate multiple TVS Diodes.”

The compact DO‑214AA package allows for quick and easy PCB layout, while compliance with IEC 61000-4-2 and IEC 610000-4-4 helps designers meet global regulatory standards.

TPSMB series automotive TVS diodes are available in tape and reel format in quantities of 3,000. Sample requests may be placed through authorised Littelfuse distributors worldwide.

Founded in 1927, Littelfuse provides circuit protection while growing global platforms in power control and sensing. The company serves customers in the electronics, automotive and industrial markets with technologies including fuses, semiconductors, polymers, ceramics, relays and sensors. Littelfuse has over 10,000 employees in more than 40 locations throughout the Americas, Europe and Asia.
