What is 2N4403?
2N4403 is a general purpose PNP transistor used for low power switching and amplifier applications. The NPN complementary for the device is 2N4400, 2N4401.
How do transistors work as a switch?
One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, the switch is off. When base voltage is present, the switch is on.
How do I convert PNP to NPN?
If you have the exact NPN equivalent you only need to mount the circuit as it is drawn, so that the base, collector and emitter terminals of the NPN are connected where base, collector and emitter of the PNP should go, and then reverse the power supply polarity.
What kind of transistor is 2n4403 NPN complementary?
2N4403 is a general purpose PNP transistor used for low power switching and amplifier applications. The NPN complementary for the device is 2N4400, 2N4401. 2N4403 has three pins like any other transistor namely EMITTER, BASE and COLLECTOR.
