BC548 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. The current supplies out through the emitter terminal It is denoted by “E”īC548 is a NPN transistor so the collector and emitter will be left open (Reverse biased) when the base pin is held at the ground and will be closed (Forward biased) when a signal is provided to the base pin. This pin controls the transistor biasing. The flow of current will be through the collector terminal.

Sometimes the middle pin is supplied bent to form a triangle of leads (as found in TO-18 case transistors and, for example, the ZTX108-L) to match the pinout of the BC108 more exactly.

lead 1 (left in diagram) is the collector,.

As viewed in the top-right image, going from left to right, the pinout is as follows: the "pinout", uses the same convention used by some - but not all - other TO-92 devices. The assignment of transistor elements (b,c,e) to leads, i.e. The BC548 is supplied in a standard TO-92 3-pin package.

We'll be glad to find that this blog can be useful for people who love electronic components. This blog gives you a basic overview of the BC548 transistor, including its pin descriptions, features, specifications, alternative products, etc., to help you quickly understand what BC548 is all about. The max collector dissipation of the device is 625 milliWatt, which is another good feature to use as a small amplifier. The BC548 is an NPN bipolar junction transistor.īC548 is another general-purpose widely used transistor that can be easily accessed from reputable electronic components store, this transistor also has lots of good features on the basis of which it can be used in their electronic circuit, it can handle a maximum current of 500mA which is sufficient to drive many other components such as ICS, other transistors, circuit portions, relays, LEDs, etc.
