Here is an image showing the pin diagram of this transistor.The 2SD733K-C transistor can have a current gain of 40 to 80. The gain of the 2SD733K will be in the range from 40 to 320, for the 2SD733K-D it will be in the range from 60 to 120, for the 2SD733K-E it will be in the range from 100 to 200, for the 2SD733K-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD733K-C might only be marked "D733K-C".The complementary PNP transistor to the 2SD733K-C is the 2SB697K-C.You can replace the 2SD733K-C with the 2N6676, 2SC2428, 2SD424, 2SD424-R, 2SD552, 2SD552-R or 2SD753.
