P4SMA20A

TVS - Diodes

TVS Diode400WSMALittelfuse

The P4SMA20A is a 400W uni-directional TVS diode in an SMA package, ideal for protecting sensitive electronics from voltage transients.

Best for

  • I/O interfaces
  • VCC bus protection
  • Telecom equipment

Avoid if

  • Applications requiring bi-directional protection (use P4SMA20CA instead)

Check before use

  • Ensure the operating voltage does not exceed the 17.1V stand-off voltage.
