The 80SQ045NG is an 8.0 Ampere Schottky barrier rectifier utilizing a metal-to-silicon power diode structure. It features epitaxial construction with oxide passivation and a guard-ring for stress protection, ensuring high stability and efficiency. This device is rated for a peak repetitive reverse voltage of 45 V, an average rectified forward current of 8.0 A, and a low maximum forward voltage of 0.55 V at its rated current. With a high surge capacity of 140 A, it is well-suited for demanding conditions. Common applications include use as rectifiers in low-voltage inverters, free-wheeling diodes, and polarity protection diodes.
