3-Channel, Low-Leakage ESD Protector

General Description

The MAX14541E low-capacitance Q15kV ESD-protection
diode array is designed to protect sensitive electronics
attached to communication lines. Each channel consists
of a pair of diodes that steer ESD current pulses to VCC
or GND.

The MAX14541E protects against ESD pulses up to
Q15kV Human Body Model (HBM) and Q15kV Air-Gap
Discharge, as specified in IEC 61000-4-2. The device
has a 6pF (typ) on-capacitance per channel, making
them ideal for use on high-speed data I/O interfaces.

The MAX14541E is a triple I/O protector designed for
biometric connectors, portable connectors, and SVGA
video connections with ultra-low leakage current.

The device is available in a 5-pin SC70 package and is
specified over the -40NC to +125NC automotive operating
temperature range.
