The SMF12A is a surface-mount Transient Voltage Suppressor (TVS) Diode manufactured by SMC Diodes. As an authorized distributor, Supreme Components International guarantees the authenticity and quality of this component. This diode is specifically designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. Featuring a breakdown voltage of 12V and a power dissipation of 400W, the SMF12A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its compact DO-219AB (SMF) package makes it suitable for high-density PCB layouts. This TVS diode is commonly used in applications such as telecommunications equipment, industrial control systems, and consumer electronics.
