Here is an image showing the pin diagram of this transistor.The 2SB709A transistor can have a current gain of 160 to 460. The gain of the 2SB709A-Q will be in the range from 160 to 460, for the 2SB709A-R it will be in the range from 160 to 460, for the 2SB709A-S it will be in the range from 160 to 460.Sometimes the "2S" prefix is not marked on the package - the 2SB709A might only be marked "B709A".The complementary NPN transistor to the 2SB709A is the 2SD601A.You can replace the 2SB709A with the 2SA1037, 2SA1366, 2SA1518, 2SA1519, 2SA1520, 2SA1521, 2SA812, BC807, BC856, BC857, BC860, BCW68, BCX17, FMMTA55, FMMTA56, KSA812, KST55, KST56, MMBT4354, MMBTA55, MMBTA56, PMBTA56, SMBTA55 or SMBTA56.
