The SMF43CA-MS-H is a Surface Mount Transient Voltage Suppressor (TVS) Diode manufactured by FORMOSA MICROSEMI. This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage of 43V and a power dissipation rating of 400W, it provides effective overvoltage protection. The SMF43CA-MS-H is housed in a DO-219AB package, making it suitable for automated assembly processes. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine and reliable products. This TVS diode is ideal for use in telecommunications, industrial control, and consumer electronics applications where robust surge protection is critical.
