Here is an image showing the pin diagram of this transistor.The 2SD667B transistor can have a current gain of 60 to 120. The gain of the 2SD667 will be in the range from 60 to 320, for the 2SD667C it will be in the range from 100 to 200, for the 2SD667D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD667B might only be marked "D667B".The complementary PNP transistor to the 2SD667B is the 2SB647B.You can replace the 2SD667B with the 2SC2383, 2SC2383R, 2SC3228, 2SC3228-R, 2SD667A, 2SD667AB, KSC2383, KSC2383R, KTC3228 or KTC3228R.
