Note: Complete Technical Details can be found at the BC transistor datasheet give at the end of this page. BC is a NPN transistor so 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. BC has a gain value of to , this value determines the amplification capacity of the transistor. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. When this transistor is fully biased, it can allow a maximum of mA to flow across the collector and emitter.

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. The BC is supplied in a standard TO 3-pin package. The assignment of transistor elements b,c,e to leads, i. As viewed in the top-right image, going from left to right, the pinout is as follows:.
