TPSMB39CA Description

Short technical summary and product information.

The TPSMB39CA is a bidirectional TVS diode from Littelfuse, part of the TPSMB series designed for automotive applications. It offers 600W peak pulse power capability at 10/1000 µs waveform, with a reverse standoff voltage of 33.3V and a maximum clamping voltage of 53.9V. The device can handle a peak pulse current of 11.3A under the same waveform.

 

This TVS diode features a fast response time of typically less than 1.0 ns from 0V to V_BR min, making it suitable for protecting sensitive electronics from voltage transients induced by lightning, ESD, and other transient events. It is AEC-Q101 qualified for high-reliability automotive applications and has an operating temperature range of -65°C to 175°C.

 

The TPSMB39CA is housed in a DO-214AA (SMB) surface-mount package, which optimizes board space. It is RoHS compliant, halogen-free, and meets MSL Level 1 per J-STD-020. The device is lead-free with matte tin plated terminals, ensuring compatibility with lead-free soldering processes.
