TWO-DIRECTIONAL ESD /TRANSIENT PROTECTION DIODE

DESCRIPTION

The UTC USM712 is TVS Diode Array is designed to protect

RS-485 applications with asymmetrical working voltages (-7V to

12V) from damage due to electrostatic discharge (ESD), electrical

fast transients (EFT), and lightning induced surges.

The USM712 can absorb repetitive ESD strikes above the

aximum level specified in the IEC61000-4-2 international

standard without performance degradation and safely issipate up

to 7A of 8/20us induced surge current (IEC61000-4-5 2nd edition)

with very low clamping voltages.

FEATURES

* 150W peak pulse power(8/20μs)

* Operating Voltages: 7V to 12V

* Low clamping voltage

* Low leakage current
