The ZGFM5939B-H is a TVS (Transient Voltage Suppressor) diode manufactured by FORMOSA MICROSEMI. This unidirectional diode is designed to protect sensitive electronic circuits from voltage transients induced by electrostatic discharge (ESD), inductive load switching, and other transient voltage events. With a breakdown voltage of 5.0V, the ZGFM5939B-H effectively clamps overvoltage conditions, preventing damage to downstream components. Its compact SOD-323 package makes it suitable for space-constrained applications. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring that you receive genuine, high-quality products. This TVS diode is ideal for use in various applications, including consumer electronics, industrial equipment, and automotive systems, where reliable overvoltage protection is crucial.
