The SMF18CA is a high-performance 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 unidirectional TVS diode is specifically designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a standoff voltage of 18V and a peak pulse power dissipation of 400W, the SMF18CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its compact DO-219AB (SMF) surface-mount package makes it suitable for high-density PCB layouts. This diode is ideal for use in a wide range of applications, including automotive, telecommunications, and industrial equipment.
