(Pack of 5) 2N4403 PNP General Purpose Transistor 40V 600mA TO-92 Package

(Pack of 5) 2N4403 PNP General Purpose Transistor 40V 600mA TO-92 Package

The 2N4403 is a high-reliability PNP general-purpose transistor designed for switching and low to medium-power amplification applications. Each transistor in this pack can handle a collector-emitter voltage of 40V and a collector current of 600mA, making it ideal for analog and digital circuits that require efficient PNP operation.

Housed in a compact TO-92 plastic package, the 2N4403 is easy to mount on PCBs and provides stable performance, low leakage current, and reliable long-term operation. Its moderate gain and low saturation voltage make it suitable for driver circuits, relay control, LED switching, and small-signal amplification.

This pack of 5 transistors is perfect for hobbyists, students, and engineers, providing spare components for prototyping, repairs, and general electronics projects.
