3 Description

The TSM36CA is a 36V, bidirectional TVS protection

diode designed for clamping harmful transients

such as ESD and surge. The TSM36CA robustly

shunts up to 20A of IEC 61000-4-5 fault current

to protect systems from high power transients or

lightning strikes. The TSM36CA device is rated to

dissipate ESD strikes up to ±30kV (contact and air

gap discharge) which exceeds the maximum level

specified in the IEC 61000-4-2 international standard

(Level 4).

Additionally, the TSM36CA 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.
