24-V, bidirectional, TVS surge-protection diode

The TSM24CA is a low-capacitance

TVS diode and is part of TI’s surge protection device family. The TSM24CA robustly shunts up to 30A of IEC 61000-4-5 (8/20 µs) fault

current to protect systems from high power transients or lightning strikes. The

device offers a solution to the common industrial signal line EMC requirement to

survive up to 1kV IEC 61000-4-5 open circuit voltage coupled through a 42Ω

impedance, clamping that surge at 40V (I PP = 24A). The TSM24CA also has a very low line capacitance of 12pF which allows

it to protect common automotive communication networks like CAN from surges in EV

charging applications.

Additionally, the TSM24CA is

available in a small leaded SOT-23 (DBZ) package which is reduced in size by

approximately 50 percent compared to the industry standard SMA package. The

extremely low device leakage and capacitance provide a minimal effect on the

protected line.
