The SMF18A-MFH-H is a Surface Mount Transient Voltage Suppressor (TVS) Diode manufactured by FORMOSA MICROSEMI. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine and reliable products. This TVS diode is designed to protect sensitive electronic equipment from voltage transients caused by lightning, inductive load switching, and ESD. It features a standoff voltage of 18V and a peak pulse power dissipation of 400W. The SMF18A-MFH-H is housed in a low-profile DO-219AB (SMF) package, making it suitable for applications where board space is limited. Its fast response time and low clamping voltage provide excellent protection against transient events. Ideal for use in communication systems, industrial equipment, and consumer electronics.
