ONSEMI 80SQ045NG Schottky Rectifier 45V 8A DO-201AD

The ONSEMI 80SQ045NG Schottky Rectifier is an axial-leaded, single diode featuring a robust epoxy moulded case with corrosion-resistant external surfaces and readily solderable terminal leads. Utilising the Schottky barrier principle in a large-area metal-to-silicon power diode, this component delivers high current capability, low stored charge, and majority carrier conduction for exceptional efficiency.

Its state-of-the-art geometry includes epitaxial construction with oxide passivation and metal overlap contact, ensuring a highly stable and reliable junction. The guard-ring design provides stress protection, while the low forward voltage and high surge capacity (140A) make it suitable for demanding power management applications. The cathode is indicated by a polarity band for easy identification.

Applications

This rectifier is ideally suited as a rectifier in low-voltage, high-frequency inverters, as well as for free wheeling diodes and polarity protection diodes. Its through-hole mounting (DO-201AD package) and 2-pin configuration simplify integration into standard PCB designs. With a repetitive peak reverse voltage of 45V and an average forward current of 8A, it meets the needs of various power supply and conversion circuits.
