Littelfuse TPSMB-L TVS

Specifically, the unidirectional diodes in the TPSMB-L series are for protecting analogue front-ends and IC in 14 to 20 cell  sub-assemblies.

There are three parts, all rated for 600W 10/1,000μs pulses (0.01% duty cycle) and come in ~3.6 x 5.3mm DO-214AA (SMB) packaging:

TPSMB75A-L 64.1V 70.4 – 78.8V 96V at 5.9A 83A 95V 29.5A
TPSMB82A-L 70.1V 77 – 86.1V 100V at 5.4A 90A 100V 27A
TPSMB91A-L 77.8V 85.4 – 95.5V 114V at 4.9A 100A 109V 24.5A

Operated in forward conduction, the drop is 3.5Vmax during a 50A pulse.

ESD protection of data lines to IEC 61000-4-2 is 30kV air and 30kV contact, according to the company, and EFT data line protection accords with IEC 61000-4-4.

The parts are AEC-Q101 qualified with PPAP Level 3 compliance.
