## **Applications** 

Data transmission lines protection, such as: 

- Unipolar signal up to 5.5 V 

- Bipolar signal in the ± 2.5 V range 

## **Description** 

Transil diode arrays  provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS technology and low voltage supplied IC’s. 

The ITA series allies high surge capability against energetic pulses with high voltage performance against ESD.
