PDF of 97.8 KB for the 40EPF-HV, filed as a schematic though it is component documentation. The 40EPF series consists of fast or soft-recovery rectifier diodes, and the HV suffix suggests a high-voltage variant; the exact rating should be read from the sheet. It provides recovery time, voltage, current and pinout data. This is useful when replacing fast diodes in PFC stages, snubbers or freewheeling paths, where a standard recovery part would not be a valid substitute.
