The ZGFM5951B-AF-H is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage of 59V, it effectively clamps overvoltage events, diverting excess current away from protected circuits. The ZGFM5951B-AF-H comes in a compact DO-214AA (SMB) package, making it suitable for space-constrained applications. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive authentic and high-performance products. This TVS diode is an excellent choice for enhancing the reliability and longevity of your electronic designs. Its robust construction and precise electrical characteristics make it a dependable solution for transient voltage protection.
