The SMA6J18CA is a robust Transient Voltage Suppressor (TVS) Diode manufactured by SMC Diodes. This diode is specifically designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a power dissipation rating of 400W and a breakdown voltage (Vbr) of 18V, the SMA6J18CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. Housed in a surface-mount SMA package, it offers easy integration into various PCB designs. Supreme Components International is an authorised distributor of SMC Diodes, ensuring you receive authentic and high-quality components. This TVS diode is suitable for applications requiring reliable overvoltage protection.
