FEATURES

DESCRIPTION

The ESDA25W is a 2-bit wide monolithic

suppressor designed to protect components

which are connected to data and transmission

lines against ESD.

It clamps the voltage just above the logic level

supply for positive transients, and to a diode drop

below ground for negative transients.

BENEFITS

n

High ESD protection level : up to 25 kV.

n

High integration.

n

Suitable for high density boards.

n

IEC61000-4-2 level 4

n

MIL STD 883C-Method 3015-6 : class 3.

(human body model)
