Reference PDF of 130 KB for the part 12CWQ10FN, filed under schematics although the name points to a single-component datasheet. The numbering resembles International Rectifier diode parts, with the suffix indicating a package option. Inside you would expect absolute maximum ratings, electrical characteristics and a mechanical outline. Use it to verify a suspected shorted rectifier, find a pin-compatible replacement, and make sure the code printed on the device matches before soldering in a substitute.
