ETP01-1621RL

ETP01-1621RL Description

The ETP01-1621RL from STMicroelectronics is a high-performance thyristor-based surge protector designed for robust circuit protection in demanding electronic applications. Part of the ETP01, TRISIL™ series, this surface-mount device offers 16V off-state voltage and a breakover voltage of 25V, ensuring reliable clamping during transient voltage events. With a peak pulse current rating of 100A (8/20µs), it provides superior ESD and surge protection, making it ideal for safeguarding sensitive components in industrial, automotive, and telecommunications systems. Its low capacitance (16pF) minimizes signal distortion, while the 30mA hold current ensures stable operation under normal conditions. Packaged in 8SOIC and supplied in Tape & Reel (TR), it is optimized for automated assembly.
