Frequently Asked Questions:
Q: What is the pinout for the BC547 TO-92 package?
A: The TO-92 package for BC547 typically has a pinout of Emitter-Base-Collector (EBC) when viewed from the flat face with leads pointing down.
Q: Can the BC547 replace a 2N3904 in general applications?
A: The BC547 has similar characteristics to the 2N3904, including NPN polarity, 100mA collector current, and TO-92 package. However, specific circuit requirements should be verified due to potential differences in gain or frequency response.
Q: What is the maximum voltage the BC547 can handle?
A: The maximum Collector-Emitter Voltage (VCEO) for the BC547 is 45VDC. The Collector-Base Voltage (VCBO) is 50VDC.
