The 2SA708O is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The 2SA708O transistor can have a current gain of 70 to 140. The gain of the 2SA708 will be in the range from 40 to 400, for the 2SA708R it will be in the range from 40 to 80, for the 2SA708Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA708O might only be marked "A708O".The complementary NPN transistor to the 2SA708O is the 2SC1008O.The KSA708O, KTA708-O is the TO-92 version of the 2SA708O.You can replace the 2SA708O with the BC527, BC527-10, BC528, BC528-10, KSA708, KSA708O, MPS4354, MPS4356, NTE159, ZTX551, ZTX552, ZTX553 or ZTX554.
