PDF of 93.0 KB named after part 10MQ100N, best treated as a component datasheet despite the schematic category. It belongs to a set that also includes 10MQ060N and 10MQ040N, which points to voltage grades of one International Rectifier style series. Expect ratings, characteristic graphs and an SMD outline drawing. Use it to confirm the reverse voltage and current capability, polarity and footprint before swapping a suspected shorted rectifier on a board.
