A 218 KB PDF covering the 10ETF02, 10ETF04 and 10ETF06 parts, filed under schematics. These names follow rectifier diode numbering of the International Rectifier and Vishay style, where the numbers after the family code usually encode voltage grade. In practice it works as a component datasheet: ratings, recovery characteristics, pinout and package dimensions. A repair technician reaches for it when a rectifier in a power stage reads shorted and a correct substitute is needed. Check the printed marking before relying on any figure.
