The SMF40CA is a Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. As an authorised distributor, Supreme Components International offers this high-quality component. This diode is specifically designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a power dissipation of 400W and a standoff voltage of 40V. The SMF40CA is packaged in a DO-219AB (SMF) package, making it suitable for surface mount applications where space is a constraint. Its fast response time and low clamping voltage ensure effective protection for your valuable equipment. This robust diode enhances the reliability and longevity of electronic systems by preventing damage from overvoltage conditions. Ideal for automotive, industrial, and consumer electronics applications.
