SMA59**A Series

SMA59**A Series Zener Diodes | High Power SMA Package | Voltage Range 3.3V-200V | Industrial Grade Temperature Characteristics

The SMA59**A Series Zener Diodes are high-power (1.5W) surface-mount devices in a compact SMA package, offering a broad breakdown voltage range from 3.3V to 200V. Featuring low dynamic impedance and stable voltage regulation characteristics, this series supports high maximum reverse currents up to 274mA (low-voltage models) with excellent leakage current control (typically 10μA). Ideal for power supply regulation, voltage clamping, and overvoltage protection in demanding applications.

  • Power supply regulation and voltage stabilization
  • Overvoltage protection in industrial and consumer electronics
  • Communication systems, motor control, and LED drivers
  • Suitable for AC-DC converters, SMPS, and low-voltage battery protection
