TPSMB39A Description

Short technical summary and product information.

The Littelfuse TPSMB39A is a 600W automotive-grade TVS diode designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 33.3V and a maximum clamping voltage of 53.9V at 11.3A peak pulse current (10/1000µs waveform). The device offers fast response time of less than 1.0ns from 0V to VBR min and provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2.

 

This TVS diode is AEC-Q101 qualified, making it suitable for automotive applications such as I/O interfaces, VCC bus protection, and on-board charger circuits. It is housed in a surface-mount DO-214AA (SMB) package with matte tin lead finish and meets MSL level 1 per J-STD-020. The device is RoHS3 compliant, halogen-free, and lead-free.

 

With a junction operating temperature range of -65°C to 175°C and thermal resistance of 20°C/W (junction-to-lead) and 100°C/W (junction-to-ambient), the TPSMB39A is robust for demanding environments. Power line protection is not supported, and the device is unidirectional with one channel.
