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:
Reverse parameters |
Stand-off at 1uA |
Break-down at 1mA |
Max clamp 10/1,000μs |
Max clamp 8/20μs 10A |
Max clamp 8/20μs |
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.
