SMA47**A Series

SMA Zener Diodes 3.3V to 200V | Voltage Regulation | Clamping Components

This SMA-packaged Zener Diode series offers a wide breakdown voltage range from 3.3V to 220V, with 1W power dissipation. These diodes provide excellent voltage regulation accuracy and low leakage current. With surge current capability up to 9990mW, they are ideal for surge suppression, voltage clamping, and power regulation across industrial and consumer electronics. Operating temperature range from -55°C to +150°C, RoHS compliant.

  • Over-voltage protection in power adapters
  • Voltage regulation and clamping in consumer electronics
  • Voltage limiting in industrial control circuits
  • Telecom port protection
