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

■ JEDEC registred SMA package outline

■ Low clamping factor VCL/VBR

■ Fast response time

■ RoHS compliant

Benefits

■ Optimized PCB area: up to 62% space saving

versus discrete solution

■ High peak pulse power: up to 600 W

■ Stand-off voltage:

5 V for SMTY5.0A

12 V for SMTY12A

■ Low forward voltage: 0.48 V @ 1 A

■ Very low leakage current:

10 µA @ 5 V for SMTY5.0A

20 µA @12 V for SMTY12A
