The 2SA708Y 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 2SA708Y transistor can have a current gain of 120 to 240. The gain of the 2SA708 will be in the range from 40 to 400, for the 2SA708O it will be in the range from 70 to 140, for the 2SA708R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA708Y might only be marked "A708Y".The complementary NPN transistor to the 2SA708Y is the 2SC1008Y.The KSA708Y, KTA708-Y is the TO-92 version of the 2SA708Y.You can replace the 2SA708Y with the BC527, BC527-16, BC528, BC528-16, KSA708, KSA708Y, MPS4354, MPS4355, MPS4356, MPS751, MPS751G, NTE159, PN2907A, ZTX554, ZTX951 or ZTX953.
