BAV21W

Component

Fast SwitchingSOD-123General Purpose200V

The BAV21W is a reliable, fast-switching diode in a SOD-123 package, ideal for general-purpose switching circuits requiring up to 200V repetitive reverse voltage.

Best for

  • General purpose switching
  • High-speed signal routing
  • Automated PCB assembly

Avoid if

  • Applications requiring >200V repetitive reverse voltage
  • High-power rectification exceeding 200mA

Check before use

  • Thermal dissipation in high-density layouts
  • Reverse recovery timing for specific high-frequency circuits
