LESHAN RADIO COMPANY, LTD.
Low Capacitance Q uad Array for ESD Protection
General Description
The LESDA6V1W5T1G 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.
