The BC528-25 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 BC528-25 transistor can have a current gain of 160 to 400. The gain of the BC528 will be in the range from 40 to 400, for the BC528-10 it will be in the range from 63 to 160, for the BC528-16 it will be in the range from 100 to 250, for the BC528-6 it will be in the range from 40 to 100.The complementary NPN transistor to the BC528-25 is the BC538-25.The 2SB805 (SOT-89), 2SD1006 (SOT-89), FMMTA56 (SOT-23), KST56 (SOT-23), MMBTA56 (SOT-23), PMBTA56 (SOT-23), PZTA56 (SOT-223) and SMBTA56 (SOT-23) is the SMD version of the BC528-25 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
