The SMF43CA-MFH-H is a high-performance TVS (Transient Voltage Suppressor) Diode manufactured by FORMOSA MICROSEMI. This diode is specifically engineered to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. Featuring a reverse standoff voltage of 43V and a peak pulse power dissipation of 400W, the SMF43CA-MFH-H provides a robust defense against overvoltage conditions. Its fast response time ensures quick clamping of transient voltages, preventing damage to downstream components. The DO-219AB package offers excellent thermal performance and ease of board mounting. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive a genuine and reliable product. Ideal for use in telecommunications equipment, industrial controls, and consumer electronics.
