The SMTPA220 is a bidirectional thyristor surge protector from STMicroelectronics. It provides overvoltage protection with a repetitive peak off-state voltage of 220V and a breakover voltage of 293V. The device can handle a peak pulse current of 50A (8/20µs waveform) and a surge current of 150A, making it suitable for robust protection in telecom and industrial applications.
Key electrical characteristics include a low capacitance of 25pF, which minimizes signal degradation in high-speed data lines. The SMTPA220 is housed in a DO-214AA (SMB) surface mount package, enabling automated assembly and compact PCB layouts. The single-element design ensures reliable bidirectional clamping.
Typical applications include protection of telecom line cards, data communication ports, and AC/DC power supply circuits. The device is designed for use in environments where transient overvoltage events are common.
