0to 5 V

APPLICATION EXAMPLE :

1 - Protection of logic-level signals.

(ex : centronics junction)

+/- 2.5 V

+/- 2. 5 V

A16

+/- 2.5 V

2 - Protection of symmetrical signals.

Note : Capacitancevalue between any I/O pin and

Ground is divided by 2.

Implementing its ASD

TM technology,SGS-Thomson

has developed a monolithic TRANSIL diode array,

which is a reliable protection against electrostatic

overloads for computer I/O ports, modems, GSM

handsetsand accessories or other similar systems

with data outputs. The ESDAxxSx integrates 18

TRANSIL diodes in a compact package that can be

easily mounted close to the circuitry to be

protected,

eliminating

the

assembly

costs

associated with the use of discrete diodes, and

also increasing system reliability.

Each TRANSIL has a breakdown voltage between

6.2V (minimum) and 7.2V (maximum). When the

input voltage is lower than the breakdown voltage,

the diodes present a high impedance to ground.

For short overvoltage pulses, the fast-acting

diodes provide an almost instantaneousresponse,

clamping the voltage to a safe level.
