The SMCJ40A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. Supreme Components International is an authorised distributor of SMC Diodes, ensuring you receive genuine components. This surface-mount TVS diode, housed in a DO-214AB (SMC) package, is specifically engineered to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a standoff voltage of 40V and a peak pulse power dissipation of 1500W, the SMCJ40A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its fast response time and low clamping voltage make it suitable for a wide range of applications, including telecommunications, industrial equipment, and consumer electronics. The SMCJ40A offers a reliable and cost-effective solution for enhancing the robustness and longevity of your electronic designs.
