![]() ![]() It just like screening eggs with different sizes. Stackexchange Nov27th, 2015įairchild Datasheet tells you all about BC54x family of transistorsīC546/547/548/549/550 is made from the same process (the same silicon die) but just different screening based on different parameters. The gain differences are not huge when comparing the 547 & 548. ![]() High voltage transistors tend to have lower gain and low voltage transistors tend to have higher gain. You will be fine with BC548, BC547 or 2N3904 your application is not demanding.Īccording to semiconductor physics gain and breakdown voltage are interchangeable. This is the project: Logic Gates with transistors Basical logic gates mae using transistors This project is about making logic gates (NOT, AND, OR) using npn transistors like bc547. There, I gave you a hands-on example! Navin Kumar Oct. Trans GP BJT NPN 45V 0.1A 500mW 3-Pin TO-92 T/R. I once used one BC547 and one BC548 for the basic astable multivibrator circuit and there were no problems. Download the BC547 datasheet from onsemi. Download schematic symbols, PCB footprints, 3D Models, pinout & datasheet for the BC547 by Onsemi. These types of bipolar transistors are made up of materials such as germanium, silicon, and gallium arsenide. ![]() It is a Bipolar Junction transistor that is commonly used to satisfy the need of quick switching. These are the most general purpose NPN silicon transistors and changing one with the other does not noticably (or otherwise) affect the circuit. The BC547 is a common NPN (Negative-Positive-Negative) transistor. BC547 and BC548 are essentially the same but BC547 has a higher breakdown voltage whereas BC548 has low noise. Can I use a Transistor BC547 instead of BC548? Quora ![]()
