A 38.6 KB PDF that combines the 6CWQ05F and 6CWQ06F, dual Schottky rectifiers likely rated at 50 V and 60 V respectively. Despite the schematic category, the name points to a component datasheet, not a circuit board. Expect maximum ratings, forward voltage curves and a package drawing with pinout. It helps when matching a replacement for a shorted output rectifier in switching power supplies. Read the full code on the original part, since the voltage grades share one sheet but are not interchangeable downward.
