Bc558 Pnp Transistor charging cable Long Power Cord: Easily reachBC558 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. This is where a PNP transistor differs from a NPN transistor. BC558 has a gain value of 110 to 800; this value determines the amplification capacity of the transistor. The peak current that could flow through the Collector pin is 200mA, this combined
