A 135 KB PDF listed as a schematic for the 201CNQ series, a family of high-current Schottky rectifier modules. Without a voltage suffix in the name, the sheet likely spans several voltage grades. The content should be a component datasheet with electrical characteristics, thermal data and an outline drawing rather than a wiring diagram. Technicians reach for it when identifying a replacement for a failed rectifier module. Read the complete code on the original part to select the correct voltage grade.
