The SMCJ20CA-A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. As an authorised distributor, Supreme Components International provides this essential component for robust circuit protection. This unidirectional TVS diode is specifically designed to protect sensitive electronic equipment from voltage transients caused by lightning strikes, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 600W and a standoff voltage of 20V, the SMCJ20CA-A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its compact SMC package ensures efficient heat dissipation and facilitates easy surface mount assembly. Ideal for use in telecommunications, industrial control, and consumer electronics applications, the SMCJ20CA-A offers reliable and cost-effective overvoltage protection.
