The SM4NT440CA-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, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 400W and a reverse standoff voltage of 44V, the SM4NT440CA-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its compact DO-214AC (SMA) package allows for easy surface mounting on printed circuit boards. This TVS diode is suitable for a wide range of applications, including telecommunications equipment, industrial controls, and consumer electronics, where reliable overvoltage protection is critical.
