BC107 NPN Transistor

• BC107 is a 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.
• BC107 has a gain value h_fe of 50; this value determines the amplification capacity of the transistor.
• The maximum amount of current that could flow through the Collector pin is 100mA, hence we cannot connect loads that consume more than 100mA using this transistor. When this transistor is fully biased then it can allow a maximum of 100mA to flow across the collector and emitter. This stage is called Saturation Region. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.
• BC107 Equivalent BC549
• PNP Complementary for BC107 BC177�

Pin Configuration

• Pin 1(Emitter)Current Drains out through emitter, normally connected to ground
• Pin 2(Base) Controls the biasing of transistor, Used to turn ON or OFF the transistor
• Pin 3(Collector)Current flows in through collector, normally connected to load
