Low forward voltage TVS: Transky™

Main applications

reverse voltages protection for 5 and 12 V

supplied IC’s

Description

The Transky is designed specifically for

miniaturized electronic devices and equipment

subject to ESD transient over-voltages. The

Transky combines the performance of a Transil™

or TVS (Transient Voltage Suppressor) and low

forward voltage Schottky diode in a monolithic

structure.

It offers both an overshoot protection in the 6.4 V

or 13.2 V clamping ranges and a negative spike

protection in the -0.48 V clamping range

compared to the -1 V with the standard Transil

family on the 5 or 12 V power line.

Its 600 W power capability offers high transient

capability with SMA package.
