Here is an image showing the pin diagram of this transistor.The 2SA624-E transistor can have a current gain of 150 to 300. The gain of the 2SA624 will be in the range from 55 to 300, for the 2SA624-C it will be in the range from 55 to 110, for the 2SA624-D it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA624-E might only be marked "A624-E".The complementary NPN transistor to the 2SA624-E is the 2SC1014-E.The 2SB1115 (SOT-89), 2SB1115-YM (SOT-89), 2SB1122 (SOT-89), 2SB1122-S (SOT-89), 2SB766A (SOT-89), BCW68 (SOT-23) and MMBT2907 (SOT-23) is the SMD version of the 2SA624-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
