ESD/TRANSIENT PROTECTION

DESCRIPTION

The UTC UESD3V3L1B is bidirectional ElectroStatic

Discharge (ESD). During transient conditions, the proprietary

clamping cell prevents over-voltage on the power line or

control/data lines, designed to protect one signal line from the

damage caused by ESD and other transients.

UTC UESD3V3L1B may be used to meet the ESD immunity

requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact

discharge).

FEATURES

* ESD Protect for 1 Line with Bi-directional

* Cable Discharge Event (CDE)

* Protect one I/O line or one power line

* Fast turn-on and Low clamping voltage

* For low operating voltage applications: 3.3V maximum

* Solid-state silicon-avalanche and active circuit triggering
