The BC527-25 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 BC527-25 transistor can have a current gain of 160 to 400. The gain of the BC527 will be in the range from 40 to 400, for the BC527-10 it will be in the range from 63 to 160, for the BC527-16 it will be in the range from 100 to 250, for the BC527-6 it will be in the range from 40 to 100.The complementary NPN transistor to the BC527-25 is the BC537-25.The FMMTA55 (SOT-23), KST55 (SOT-23), MMBT4354 (SOT-23), MMBT4355 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the BC527-25 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC527-25 with the BC528, BC528-25, MPS4354, MPS4355, MPS751 or MPS751G.
