3 Description

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.
