The BD242C is a 3A 100V PNP Bipolar Power Transistor designed for use in general purpose amplifier and switching applications. BD241C (NPN), BD242B (PNP) and BD242C (PNP) are complementary devices.
The BC558 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.
The BD243C is a 6A, 100V NPN Bipolar Power Transistor is designed for use in general purpose amplifier and switching applications. BD243B, BD243C (NPN); BD244B, BD244C (PNP) are complementary devices.
