TVS - Diodes

TVS DiodeSOD-123FL200W

The SMF18A is a 200W unidirectional TVS diode in a SOD-123FL package, suitable for protecting sensitive electronics from voltage transients.

Best for

  • General ESD and surge protection in space-constrained PCB designs.

Avoid if

  • Applications requiring higher power dissipation than 200W or bidirectional protection.

Check before use

  • Verify the peak pulse current (IPP) and clamping voltage (VC) match your circuit's protection requirements.
