The SMF120A-MS-Q1-H is a Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. As an authorized distributor, Supreme Components International guarantees the authenticity and quality of this component. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a standoff voltage of 120V and a peak pulse power dissipation of 400W. The SMF120A-MS-Q1-H is housed in a low-profile DO-219AB (SMF) surface-mount package, making it suitable for high-density PCB applications. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. This robust TVS diode is ideal for use in various applications, including automotive, industrial, and consumer electronics.
