The SM4NT120CA-H is a high-performance 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 bidirectional TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a power dissipation rating of 400W and a breakdown voltage of 12V, the SM4NT120CA-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its DO-214AC (SMA) package allows for easy surface mounting and efficient heat dissipation. This TVS diode is suitable for a wide range of applications, including automotive electronics, industrial equipment, and consumer electronics, where reliable overvoltage protection is critical.
