The Microsemi 5820SM series provides 3 A Schottky barrier rectifiers with low forward voltage and high reliability for surface‑mount applications. The devices feature a guard‑ring protection structure and are available in multiple voltage ratings (20 V, 40 V, 65 V).\n\nKey specifications include an average forward current of 3 A, a maximum surge current of 150 A (8.3 ms half‑sine), typical junction capacitance of 265 pF, and a maximum thermal resistance of 20 °C/W. The rectifiers operate over a wide temperature range (‑55 °C to 150 °C) and are supplied in standard SMD packages.
