Automotive dual Transil™ array for ESD protection

Features

Benefits

Complies with the following standards

Ω

– 30 kV (air discharge)

– 30 kV (contact discharge)

Ω

– 30 kV (air discharge)

– 30 kV (contact discharge)

Applications

Where transient overvoltage protection in ESD

sensitive equipment is required, such as:

Description

The ESDALY is a monolithic array designed to

protect 1 line or 2 lines against ESD transients.

The device is ideal for applications where both

reduced line capacitance and board space saving

are required. It can also be used as bidirectional

suppressor by connecting only pin 1 and 2.
