The 3.0SMI40A 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 diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a reverse standoff voltage of 40V and a peak pulse power dissipation of 3000W, the 3.0SMI40A offers robust overvoltage protection. Its fast response time and low clamping voltage ensure effective protection for downstream components. Ideal for use in telecommunications, industrial control, and consumer electronics applications, this TVS diode provides a reliable and cost-effective solution for enhancing system reliability and preventing costly damage from voltage surges.
