The utility model discloses a diode combination device with short reverse recovery time. The diode combination device comprises a diode, a packaging shell, a first pin and a second pin, the number of the diodes is at least two, and all the diodes are packaged in the packaging shell in series in the forward direction. One end of the first pin and one end of the second pin are arranged in the packaging shell and are respectively connected with the two ends of all the diodes which are connected in series; the other end of the first pin and the other end of the second pin are located outside the packaging shell. According to the utility model, the at least two diodes are connected in series in the forward direction, so that the reverse recovery time TRR can be reduced, and the diodes are packaged in the packaging shell after being connected in series in the forward direction, so that the light emitting diode becomes a combined device, and the welding spots of the PCB are not increased; and the working frequency o
