The SMF13A-MS-Q1-H is a Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. This unidirectional TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a breakdown voltage of 13V and a peak pulse power dissipation of 400W, it provides robust protection in a small DO-219AB (SMF) package. Its unidirectional configuration makes it suitable for applications where protection against positive voltage transients is required. Supreme Components International is an authorized distributor of FORMOSA MICROSEMI, guaranteeing the authenticity and quality of this TVS diode. This component is ideal for use in automotive, industrial, and consumer electronics applications where reliable overvoltage protection is critical.
