SPT02-236DDB   Product is in volume production.

Automation sensor transient and overvoltage protection

Download Datasheet

The SPT02 is specifically designed for the protection of 24 V proximity sensors. It implements the reverse polarity and the overvoltage protection of the sensor power supply and the power switch overvoltage protection.

It provides a very compact and flexible solution.

Thanks to high performance ST technology, the SPT02 protects the proximity sensor to the highest level compliant with IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 standards.
