The TIP127G by ON Semiconductor is a power PNP Darlington transistor with a bipolar arrangement, rated for 5A and 100V. This Darlington configuration offers higher gain over a wide bandwidth, allowing for easier control of switching speeds. Moreover, its low saturation voltage and high peak current capability makes it ideal for power switching applications. Moreover, it is temperature compensated for lower switching losses due to its built-in temperature compensation circuitry. This part is especially useful for driver circuits, relay and solenoid control, and high-current switching.
