A datasheet-style PDF of 80.7 KB for the 162cnq030, categorised as a schematic in this index. The CNQ code pattern belongs to dual Schottky rectifiers in larger power packages, and 030 normally denotes a 30 V rating. Technicians consult it for forward voltage, per-leg current, thermal resistance and pin arrangement when a rectifier on the secondary of a switching supply has failed. Open it in any PDF reader and compare the full case marking, since CMQ and CNQ versions differ in package.
