The ZGFM5919B-AF-Q1-H is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. This diode is specifically designed to protect sensitive electronic components from voltage transients induced by electrostatic discharge (ESD), inductive load switching, and other transient voltage events. Featuring a breakdown voltage of 5.0V, the ZGFM5919B-AF-Q1-H effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its compact SOD-523 package makes it ideal for space-constrained applications. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive a genuine and reliable product. This TVS diode is suitable for use in a wide range of applications, including consumer electronics, industrial equipment, and automotive systems.
