SMTYxxA
Low forward voltage TVS: TranskyTM
Main applications

Power rail ESD transient over-voltages and 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 TransilTM 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.

K
