![]() To bias a transistor, we have to supply current to base pin, this current (I B) should be limited to 5mA. ![]() 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. This is where a PNP transistor differs from a NPN transistor, a Logic state (blue colour) is used to toggle between Ground and Signal Voltage (Emitter-Base Voltage V BE) as shown belowīC557 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. Note: Complete Technical Details can be found at the BC557 datasheet given at the end of this page.īC157, BC558, 2N3906, 2SA1943, BD140, S8550, TIP127, TIP42īC557 is a PNP transistor hence the collector and emitter will be closed (Forward biased) when the base pin is held at ground and will be opened (Reverse biased) when a signal is provided to base pin. Continuous Collector current (I C) is 100mA.
