The ZGFM1043B-MS-H is a unidirectional TVS diode manufactured by Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components, ensuring you receive genuine and reliable products. This TVS diode is designed to protect sensitive electronic circuits from voltage transients caused by electrostatic discharge (ESD), inductive load switching, and other transient voltage events. Featuring a 43V standoff voltage, the ZGFM1043B-MS-H effectively clamps transient voltages to a safe level, preventing damage to downstream components. Its unidirectional configuration provides protection against positive voltage surges. The compact SOD-323 package allows for easy integration into space-constrained applications. This TVS diode is suitable for use in a wide range of applications, including consumer electronics, industrial equipment, and automotive systems.
