Here is an image showing the pin diagram of this transistor.The 2SB805 transistor can have a current gain of 90 to 400. The gain of the 2SB805-KK will be in the range from 200 to 400, for the 2SB805-KL it will be in the range from 135 to 270, for the 2SB805-KM it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SB805 might only be marked "B805".The complementary NPN transistor to the 2SB805 is the 2SD1006.You can replace the 2SB805 with the 2SB806, 2SD1006 or 2SD1007.
