SMAJ350CA Product Details

The "SMAJ350CA" is a popular diode and is part of the SMAJ350CA series of transient voltage suppressor diodes (TVS diodes). It is designed to protect electronic circuits from voltage spikes and transient events.



  • Unidirectional TVS diode (protects against positive voltage transients).

  • Stand-off voltage (Vwm): 350V.

  • Breakdown voltage (Vbr): 390V minimum.

  • Low leakage current and fast response time.

  • Low clamping voltage during transient events.


  • Overvoltage protection in electronic circuits.

  • ESD (Electrostatic Discharge) protection for sensitive components and integrated circuits.

  • Protection against voltage surges caused by lightning strikes or other power surges.

  • Used in various electronic systems like power supplies, communication equipment, industrial control systems, and more.
