Here is an image showing the pin diagram of this transistor.The 2SD667A transistor can have a current gain of 60 to 200. The gain of the 2SD667AB will be in the range from 60 to 120, for the 2SD667AC it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SD667A might only be marked "D667A".The complementary PNP transistor to the 2SD667A is the 2SB647A.You can replace the 2SD667A with the 2SC2383, 2SC3228, KSC2383 or KTC3228.
