The SMCJ400A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This surface-mount device is specifically engineered to safeguard sensitive electronic equipment against transient voltage events. With a standoff voltage of 400V and a robust peak pulse power dissipation of 1500W, the SMCJ400A effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its SMC package allows for efficient heat dissipation and easy integration into printed circuit boards. Ideal for applications requiring reliable overvoltage protection, such as power supplies, communication systems, and industrial equipment. Supreme Components International is an authorized distributor of JSCJ components, guaranteeing genuine products and expert support. This TVS diode offers superior protection against ESD, EFT, and lightning strikes.
