SMAJ30CA

TVS - Diodes

TVS DiodeBidirectional400WSMA

The SMAJ30CA is a 400W bidirectional TVS diode designed for transient voltage suppression in surface-mount applications.

Best for

  • ESD protection
  • Surge suppression in low-voltage DC lines

Avoid if

  • Applications requiring power dissipation significantly above 400W
  • High-frequency signal lines where parasitic capacitance may be an issue

Check before use

  • Clamping voltage at expected peak current
  • Thermal derating requirements
