The SMF43CA is a Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. As an authorized distributor, Supreme Components International guarantees the authenticity 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. With a standoff voltage of 43V and a peak pulse power dissipation of 400W, the SMF43CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its DO-219AB package allows for efficient heat dissipation and easy board mounting. This TVS diode is suitable for a wide range of applications, including automotive, industrial, and consumer electronics.
