The P4SMA120A is a Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), inductive load switching, and other transient voltage events. Featuring a reverse standoff voltage of 120V and a peak pulse power dissipation of 400W, the P4SMA120A provides a robust clamping voltage to protect downstream circuitry. Its fast response time and low clamping voltage make it suitable for a wide range of applications, including automotive, telecommunications, industrial control, and consumer electronics. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring you receive a genuine and high-quality product. The P4SMA120A comes in a surface-mount SMA package, facilitating easy assembly and efficient heat dissipation.
