Datasheet for the 6CWQ04FN in a 130 KB PDF, a dual common-cathode Schottky rectifier in the 6CWQ family; the 04 code most likely corresponds to a 40 V grade, and FN marks the surface-mount variant. No laptop or board model is stated. Use it for pinout, forward drop, current and thermal limits when replacing an output rectifier on a DC-DC or power supply board. Any PDF viewer opens it. Confirm the original marking and footprint before fitting a higher-voltage substitute.
