Here is an image showing the pin diagram of this transistor.The 2SB709A-Q transistor can have a current gain of 160 to 460. The gain of the 2SB709A 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-Q might only be marked "B709A-Q".The complementary NPN transistor to the 2SB709A-Q is the 2SD601A-Q.You can replace the 2SB709A-Q 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.
