LESDA6V1W6T1G
S-LESDA6V1W6T1G
Transil array for data protection
General Description
Features
The LESDA6V1W6T1G is a monolithic suppressor
designed to protect components connected to data
and transmission lines against ESD. The device
clamp the voltage just above the logic level supply
for positive transients, and to a diode drop below
ground for negative transients.
