The 20KPA40A TVS Diode, manufactured by SMC DIODES and available from Supreme Components International, an authorised distributor, provides exceptional protection against transient voltage events. This unidirectional diode is specifically engineered to safeguard sensitive electronic components from voltage surges induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a reverse standoff voltage of 40V and a substantial peak pulse power dissipation of 20000W, the 20KPA40A effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its robust construction and high surge capability make it suitable for a wide range of applications, including power supplies, telecommunications equipment, industrial control systems, and automotive electronics. The unidirectional configuration ensures optimal performance in DC circuits, providing reliable overvoltage protection in critical applications. Supreme Components International guarantees the authenticity and quality of this SMC DIODES product.
