The SM4NT240A-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 diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, ESD, and inductive load switching. With a breakdown voltage of 24V and a power dissipation of 400W, the SM4NT240A-H effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its compact SOD-123 package makes it suitable for space-constrained applications. This TVS diode is widely used in automotive, industrial, and consumer electronics for robust overvoltage protection.
