B0540WS

Diodes - Rectifiers - Single

Schottky DiodeSOD-32340V0.5A

The B0540WS is a 40V, 0.5A Schottky barrier diode in a SOD-323 package, ideal for low-voltage, high-speed switching and transient protection.

Best for

  • Low-voltage rectification
  • Transient protection
  • General-purpose switching

Avoid if

  • Applications requiring high-voltage blocking (>40V)
  • High-current power supplies (>0.5A)

Check before use

  • Thermal derating at high ambient temperatures
  • Forward voltage drop at your specific operating current
