The 3SMC120A is a high-power Surface Mount TVS Diode manufactured by CENTRAL SEMICONDUCTOR. Designed to protect sensitive electronic components from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD), this diode offers a robust and reliable solution. With a peak pulse power dissipation of 3000W and a standoff voltage of 120V, the 3SMC120A effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its surface mount package allows for easy integration into printed circuit boards. Supreme Components International is an authorised distributor of CENTRAL SEMICONDUCTOR, ensuring that you receive only genuine, high-quality components. This TVS diode is suitable for a wide range of applications, including telecommunications equipment, industrial controls, and consumer electronics.
