SMTPA100 Description

Short technical summary and product information.

The SMTPA100 is a TVS thyristor designed for overvoltage protection. It features a breakover voltage of 133V and a peak pulse current rating of 50A. The device has a low capacitance of 35pF, making it suitable for high-speed signal lines.

 

This thyristor is housed in a surface mount DO-214AA (SMB) package, which is compatible with standard SMD assembly processes. The single-element design provides reliable crowbar protection against transient overvoltages.

 

Typical applications include telecom infrastructure, data lines, and power supply protection where fast response and low capacitance are required. The part is RoHS3 compliant and REACH unaffected, though compliance is unverified.
