3 Description

The TSM36A is a part of TI's surge protection device

family. The TSM36A robustly shunts up to 41 A of

IEC 61000-4-5 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 1.7 kV IEC

61000-4-5 open circuit voltage coupled through a 42

Ω impedance. The TSM36A clamps during a surge

event, assuring system exposure below 50 V at I PP =

25 A.

Additionally, the TSM36A 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 ensures a minimal

effect on the protected line.
