Here is an image showing the pin diagram of this transistor.The 2SB766A transistor can have a current gain of 85 to 340. The gain of the 2SB766A-Q will be in the range from 85 to 170, for the 2SB766A-R it will be in the range from 120 to 240, for the 2SB766A-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SB766A might only be marked "B766A".The complementary NPN transistor to the 2SB766A is the 2SD874A.
