The SMF45CA-MS-H is a Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. This unidirectional TVS diode is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a standoff voltage of 45V and a power dissipation of 400W, the SMF45CA-MS-H effectively clamps overvoltage events, preventing damage to downstream circuitry. Its compact DO-219AB (SMF) package allows for easy surface mounting on printed circuit boards. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine and high-quality products. This TVS diode is suitable for use in telecommunications equipment, industrial controls, consumer electronics, and other applications requiring robust overvoltage protection.
