Diodes

SchottkyRectifierSMA2A40V

The B240A is a 2A, 40V Schottky barrier rectifier in an SMA package, designed for high-efficiency surface-mount applications.

Best for

  • General purpose rectification
  • Low-voltage power supplies
  • DC-DC converters

Avoid if

  • Applications requiring reverse voltages > 40V
  • Extremely space-constrained designs where smaller packages like SOD-123 are required

Check before use

  • Thermal dissipation requirements
  • Peak surge current limits
