MSR860G

MSR860G Description

The MSR860G from onsemi is a high-performance general-purpose rectifier diode designed for demanding power electronics applications. Part of the SWITCHMODE™ series, it offers a robust 600V reverse voltage (Vr) rating and an 8A average rectified current (Io), making it suitable for high-efficiency power conversion. With a fast recovery time of ≤500ns and a reverse recovery time (trr) of 120ns, this diode minimizes switching losses, enhancing performance in high-frequency circuits. Its low forward voltage drop (1.7V @ 8A) ensures reduced power dissipation, improving thermal management. Packaged in a TO-220-2 through-hole format, the MSR860G is ideal for applications requiring reliable, high-current rectification.
