Bruckewell Technology Corp., Ltd.

Ultra Low forward voltage TVS

FEATURES

The device is designed specifically for miniaturized electronic devices and

equipment subject to ESD transient over-voltages.

Integration of a TVS (Transient Voltage Suppressor) with

a low forward voltage Schottky diode in a device

• It offers both an overshoot protection in the 13.2 V clamping ranges

and a negative spike protection in the 0.48 V

• Very thin package (1.0 mm overall component height)

• Fast response time

• Low leakage current

Transient protection for data lines to

IEC 61000-4-2 (ESD) ±25kV (air), ±10kV (contact)

IEC 61000-4-4 (EFT) 40A (5/50ns)

IEC 61000-4-5 (Lightning) 24A (8/20µs)

Working voltages: 12V
