BC547 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. It just like screening eggs with different sizes. BC547 is an NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 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. There, I gave you a hands-on example!

I once used one BC547 and one BC548 for the basic astable multivibrator circuit and there were no problems. The sensitivity of the circuit is adjustable and can be adjusted by a variable resistor of 300K ohms. The sensor is very sensitive to raindrops. These are the most general purpose NPN silicon transistors and changing one with the other does not noticably (or otherwise) affect the circuit. The main component of this circuit is a BC547B transistor that is working as a switch in this circuit. Availability: In stock SKU: 768885 Add to Wishlist IC type: BC547 SMD Storage temperature: -65 to 150 degree celsius Total Power Dissipation: Max 250 mW VCBO (collector-base voltage): Max. 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?
