SMP50-200

SMP50-200 Description

The SMP50-200 from STMicroelectronics is a high-performance surface-mount thyristor designed for robust circuit protection in demanding applications. Part of the SMP, TRISIL™ series, it offers a 200V off-state voltage and excels in suppressing transient voltage spikes with a peak pulse current of 50A (10/1000µs) and 150A (8/20µs). Its low capacitance (25pF) ensures minimal signal distortion, making it ideal for high-speed data lines. Compliant with ROHS3 and REACH standards, this DO-214AC (SMA) packaged device is suitable for automated assembly with Tape & Reel (TR) packaging and MSL 1 (Unlimited) moisture sensitivity.

SMP50-200 Features

• High Surge Handling: Supports 150A (8/20µs) and 50A (10/1000µs) peak pulse currents for reliable transient suppression.
• Low Clamping Voltage: Breakover voltage of 267V ensures protection for sensitive components.
• Compact & Efficient: Surface-mount (SMA) design with 25pF capacitance minimizes board space and parasitic effects.
• Robust Compliance: ROHS3, REACH Unaffected, and EAR99 certifications ensure global usability.
