PDF document of 203 KB filed as a schematic and named only 80CNQ035A. No device, motherboard number or revision is stated, and the code follows the pattern of a semiconductor part number rather than a PCB designation. Treat it as a reference sheet for one component: pin layout, maximum ratings and characteristic curves. Repair use includes verifying diode orientation in a dual common-cathode style package and testing it with a multimeter in diode mode. Match the printed part marking, suffix included, before substituting.
