SMTYXXA Datasheet, PDF (1/7 Pages) STMicroelectronics – Low forward voltage TVS: Transky™

SMTYxxA
Low forward voltage TVS: Transky™
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 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.
Features
■ Integration of a Transil with a Schottky diode
