TVS - Diodes

TVS DiodeBidirectionalSMACircuit Protection

The SMAJ28CA is a 400W bidirectional TVS diode designed for transient voltage protection in compact electronic circuits.

Best for

  • I/O interface protection
  • AC/DC power supply transient suppression
  • Signal line protection (RS232/RS485)

Avoid if

  • Applications requiring higher than 400W peak pulse power
  • Unidirectional protection requirements

Check before use

  • Operating temperature range
  • Clamping voltage compatibility with downstream ICs
