Reference PDF of 142 KB for the 220CMQ030, a CMQ-series part closely related to the CNQ Schottky modules, likely differing in package or mounting style. The name does not reveal a device or board, so treat the file as a component datasheet. The 030 suffix commonly indicates a 30 V rating. Use it to check pin assignment, mounting torque, current capability and thermal data when repairing high-current rectifier stages. Compare the physical package against the drawings before treating a CNQ and CMQ part as interchangeable.
