A 129 KB PDF covering the 208CMQ060, a CMQ-family Schottky rectifier whose 060 suffix usually marks a 60 V reverse voltage. The name points to a component datasheet rather than a device schematic, with no board or model given. Use it to check maximum average forward current, surge rating, thermal resistance and terminal layout when diagnosing or replacing a rectifier in a high-current supply. Since CMQ and CNQ variants may use different packages, compare dimensions with the original part before mounting.
