SMP50-100 Description

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.

SMP50-100 Features

  • High Surge Current Handling: Supports 150A (8/20µs) and 50A (10/1000µs) transient suppression.
  • Low Capacitance (35pF): Minimizes signal distortion in high-frequency applications.
  • Surface-Mount Design (DO-214AC): Compact footprint for PCB integration.
  • Wide Voltage Range: 100V off-state voltage and 133V breakover voltage for versatile protection.
  • Reliable Performance: 150mA hold current ensures stability against false triggers.
  • Environmental Compliance: ROHS3 and REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity.
  • Automotive & Industrial Grade: Robust construction for harsh environments.

SMP50-100 Applications

  • Telecommunications: Protects DSL, Ethernet, and RF interfaces from lightning-induced surges.
  • Automotive Electronics: Safeguards ECUs, sensors, and infotainment systems from load-dump transients.
  • Industrial Controls: Used in PLC I/O modules, motor drives, and power supplies for overvoltage clamping.
  • Consumer Electronics: Ideal for USB ports, HDMI lines, and power adapters requiring ESD protection.
  • Renewable Energy Systems: Protects solar inverters and battery management systems from voltage spikes.

Conclusion of SMP50-100

The SMP50-100 stands out as a high-reliability thyristor surge protector with superior transient suppression and low parasitic capacitance, making it a top choice for high-speed and high-voltage applications. Its compact SMA package, combined with industrial-grade durability, ensures seamless integration into modern electronics while meeting stringent environmental standards. Whether for automotive, telecom, or industrial systems, the SMP50-100 delivers robust protection with minimal performance trade-offs, solidifying its position as a best-in-class solution for surge protection challenges.
