TPA120 Description

Short technical summary and product information.

The STMicroelectronics TPA120 is a single-element thyristor designed for circuit protection applications. It features a breakover voltage of 160V and a current rating of 50A, with a capacitance of 30pF. The device is housed in a DO-204AC (DO-15) axial leaded package, suitable for through-hole mounting.

 

This thyristor is intended for use in overvoltage protection circuits where reliable switching and low capacitance are required. The 30pF capacitance makes it suitable for high-frequency signal lines where minimal loading is critical.

 

The DO-204AC package offers robust mechanical stability and is compatible with standard through-hole assembly processes. The single-element design simplifies integration into protection arrays.
