What is a BC548 transistor?
BC548 transistor. The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment. It is notably often the first type of bipolar transistor hobbyists encounter and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required.
What is the pinout of the BC548?
The BC548 is supplied in a standard TO-92 3-pin package. The assignment of transistor elements (b,c,e) to leads, i.e. the “pinout”, uses the same convention used by some – but not all – other TO-92 devices. As viewed in the top-right image, going from left to right, the pinout is as follows: lead 3 is the e mitter.
What are the different gain groups of the BC548?
The BC548 is available in three different gain groups:. “A” indicates low gain (110 to 220, typically 180) at 2 mA collector current, “B” indicates medium gain (200 to 450) “C” indicates high gain (420 to 800)
What is the maximum collector current for a BC547?
Some manufacturers specify their parts with higher ratings, for example the Fairchild 1997 datasheet (547ABC, Rev B) for the BC547, sourced from Process 10 gave 500mA as the maximum collector current, while their datasheets dated 2002 have dropped the current rating to the standard 100mA.

Which of these are the leads on a BC548 transistor?
BC548 is general purpose silicon, NPN, bipolar junction transistor. It is used for amplification and switching purposes. The current gain may vary between 110 and 800. The maximum DC current gain is 800.
Does transistor increase current or voltage?
Transistor is a current controlled current device. So it amplifies current and not voltage.
