24-V, 30-kV, unidirectional surge-protection diode

The TSM24B is a part of TI’s

surge protection device family. The TSM24B robustly shunts up to 20 A

of IEC 61000-4-5 fault current to protect systems

from high power transients or lightning strikes.

The TSM24B is rated to

dissipate ESD strikes beyond the maximum level

specified in the IEC 61000-4-2 international

standard (±30-kV contact, ±30-kV air-gap). The TSM24B clamps during a surge event,

keeping system exposure below 33 V (typical) at I

PP = 20 A.

Additionally, the TSM24B 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 device

is designed to have a minimal effect on the protected line due to extremely low

device leakage.
