SMAJ20A product

SMAJ20A

Transient Voltage Suppressors (TVS)

TVS Diode400WSMA

The SMAJ20A is a 400W unidirectional TVS diode designed for transient voltage suppression in surface-mount applications.

Best for

  • General surge protection
  • Voltage clamping in low-power circuits

Avoid if

  • High-power surge environments exceeding 400W
  • Applications requiring bidirectional protection (use SMAJ20CA instead)

Check before use

  • Verify the unidirectional polarity matches your circuit requirements.
