The SMCJ120A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components, ensuring you receive genuine and reliable parts. This surface-mount diode, housed in an SMC package, offers exceptional protection against transient voltage events. With a reverse standoff voltage of 120V and a peak pulse power dissipation of 1500W, the SMCJ120A effectively clamps voltage spikes, preventing damage to downstream circuitry. It is suitable for protecting I/O interfaces, VCC bus, and other vulnerable components in telecommunications, industrial, and consumer electronics applications. Its fast response time and low clamping voltage make it an excellent choice for safeguarding sensitive equipment from ESD, EFT, and lightning surges. The SMCJ120A meets industry standards for surge protection and offers a cost-effective solution for enhancing system reliability.
