SMCJ30A product

SMCJ30A

Transient Voltage Suppressors (TVS)

TVS Diode1500WSMC

The SMCJ30A is a 1500W unidirectional TVS diode designed for transient voltage protection in surface-mount applications.

Best for

  • Circuit protection
  • Voltage transient suppression

Avoid if

  • Applications requiring bidirectional protection (use the CA suffix version instead)

Check before use

  • Verify the peak pulse current (Ipp) and clamping voltage (Vc) for your specific surge event.
