TIP2955G is a PNP power transistor formed by using a high cell density HBT technology. It is used as a switch to turn one drive voltage or current component on or off. The device changes an input signal into a power signal for on/off control. It features high gain, low collector-emitter saturation voltage and excellent thermal stability.

TIP2955G is an ideal choice for driving loads such as lamps, relays, motors and solenoids. The key parameters to be considered when selecting TIP2955G transistors are its Collector to Emitter Voltage (Vce), Collector Cutoff Current (Ic), Collector Saturation Voltage (Vcc) and Collector Switching Frequency (fT).

Working Principle:

TIP2955G transistors operate on the basic principles of bipolar junction transistor (BJT) operation. In order to switch on or off, the device uses the voltage or current supplied to the base connector to control the current flow from the collector to the emitter.

When an input signal is applied to the base connector, a small electric current is generated inside the transistor. This electric current then controls the flow of current from the collector to the emitter by raising or reducing the potential barrier between them.

When the potential barrier between the collector and the emitter is low, the current flow between them becomes larger. This allows the device to turn on and draw current from the collector. When the potential barrier is high, the current flow between them becomes smaller and the device turns off.

In addition to the control of current, TIP2955G transistors also feature high gain and low collector-emitter saturation voltage, making them suitable for applications where high accuracy is required. Moreover, they are also mechanically robust and feature excellent thermal stability, making them an ideal choice for driving loads such as lamps, relays, motors and solenoids.
