The TIP112G Power NPN Darlington Transistor is manufactured by ON Semiconductor and is a bipolar power transistor in a Darlington configuration. The device has a maximum current rating of 2 Amps, and maximum breakdown voltage of 100V. It is designed for various medium to high power switching and amplifier applications. It is a complete monolithic design that includes the NPN transistors and built-in resistors. Additionally, the device has a low saturation voltage, high hFE, robust and reliable construction, and can be used at frequencies up to 5 MHz. This device can also be used to replace a pair of discrete NPN transistors in a Darlington configuration.
