TPSMAJ12A

TVS - Diodes

TVS diodeunidirectional12 V400 WSMADO-214AC

TPSMAJ12A is a unidirectional 12 V SMA TVS diode rated for 400 W peak pulse power on a 10/1000 µs waveform. It clamps at up to 19.9 V at 20.1 A.

Best for

  • 12 V rail transient suppression
  • General surge-clamping circuits
  • Surface-mount protection designs

Avoid if

  • Bidirectional surge protection is required
  • A protected circuit cannot tolerate up to 19.9 V clamping voltage

Check before use

  • Confirm unidirectional orientation
  • Validate pulse energy and waveform against the application
  • Verify SMA DO-214AC footprint dimensions
