The ESDD12VD3 is a Transient Voltage Suppressor (TVS) Diode manufactured by JSCJ (JCET). This diode is specifically designed to protect sensitive electronic components from voltage transients induced by electrostatic discharge (ESD), inductive load switching, and other transient voltage events. With a breakdown voltage of 12V, the ESDD12VD3 effectively clamps overvoltage conditions, preventing damage to downstream circuitry. Its SOD-323 package offers a small footprint, making it suitable for high-density PCB layouts. Supreme Components International is an authorized distributor of electronic components, ensuring you receive genuine and high-quality components. This TVS diode is commonly used in applications such as data lines, I/O ports, and power supplies to enhance system reliability and prevent failures caused by transient voltage surges.
