The TPSMB400A-A is a Zener TVS diode from Littelfuse designed for transient voltage suppression in automotive and high-reliability applications. It offers a peak pulse power of 600W (10/1000 µs waveform) with a clamping voltage of 548V. The device features a fast response time of less than 1.0 ns from 0V to VBR min, making it suitable for protecting sensitive electronics from voltage transients induced by lightning and other events.
This unidirectional TVS diode is housed in a DO-214AA (SMB) surface mount package with matte tin lead-free termination. It is halogen-free and RoHS-compliant, and meets MSL Level 1 per J-STD-020. The device is AEC-Q101 qualified for automotive applications.
Key specifications include a peak pulse current of 1.1A under 10/1000 µs waveform, operating temperature range of -65°C to 150°C, and it is not intended for power line protection. The TPSMB series is ideal for I/O interfaces, VCC bus, and on-board charging circuits.
