The SMA6J40CA is a high-performance, 600W bidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. This surface-mount device is specifically designed to protect sensitive electronic equipment from voltage transients caused by lightning strikes, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage of 40V, the SMA6J40CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its bidirectional configuration makes it suitable for AC and DC applications. Supreme Components International is an authorised distributor of SMC DIODES, ensuring you receive genuine, high-quality components. This TVS diode is commonly used in I/O interfaces, VCC bus lines, and other applications requiring robust transient voltage protection. Its compact SMA package allows for easy integration into existing designs.
