TVS - Diodes

TVS Diode1500WSurface MountLittelfuse

The SMCJ51A is a 1500W uni-directional TVS diode from Littelfuse, designed for surface mount protection against voltage transients in telecom, industrial, and consumer applications.

Best for

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

Avoid if

  • Applications requiring bi-directional protection (use SMCJ51CA instead)

Check before use

  • Verify the transient energy levels in your circuit against the 1500W rating.
