Circuit Protection Thyristors

SMP50-100 Description

The SMP50-100 from STMicroelectronics is a high-performance thyristor surge protector designed for robust circuit protection in demanding electronic applications. Part of the SMP, TRISIL™ series, this surface-mount device offers a 100V off-state voltage and exceptional surge-handling capabilities, including a 150A peak pulse current (8/20µs) and 50A peak pulse current (10/1000µs). With a breakover voltage of 133V and a low hold current (Ih) of 150mA, it ensures reliable overvoltage protection while minimizing false triggering. Its 35pF capacitance and DO-214AC (SMA) package make it suitable for high-speed and space-constrained designs. Compliant with ROHS3 and REACH standards, the SMP50-100 is ideal for industrial, automotive, and telecommunications systems.
