The PIMC31,115 is a pre-biased topologies array of bipolar junction transistors (BJT) enabling simultaneous high-current gain and low leakage current of the overall circuit. The device comprises a small series of transistors with the same polarity connected in a small space in the same package, with each individual transistor using the same base-emitter voltage. This unique feature of the PIMC31,115 means that it is able to achieve the same high level of efficiency as more traditional BJT arrays even when the current gain and leakage current requirements are higher. The working principle of the PIMC31, 115 can be understood by examining the transistor arrangement shown in Figure 1. In this arrangement, each transistor is connected in series with a single shared base-emitter voltage. This connection ensures that each transistor is exposed to the same collector to base voltage (Vcb) and bias voltage (Vbe). Moreover, the interconnection of the transistors enables the base-emitter voltage of each transistor to be different from that of the other transistors in the array. The PIMC31, 115 also features a built-in current-limited load - a diode-based device that limits the amount of current that can pass through the system. This is a necessary feature as the high level of current and the associated surge currents which may occur can be damaging to the individual transistors. The PIMC31, 115 array is an especially useful device for applications in which the current gain and leakage current must be strictly controlled. These applications include power amplifiers, linear regulators, DC-DC converters, and motor controls. In addition, the PIMC31,115 can be used as an AC switch, allowing switching between two different voltage values without any need for an external voltage control. The PIMC31, 115 also offers a wide range of options for customization and is therefore ideal for those who wish to design their own devices. For example, the base-emitter voltage can be changed from the standard 2V to as low as 0.1V, and the current at which the load starts to take effect can be set as low as 1mA. The PIMC31,115 has a wide range of applications, many of which could not easily be achieved without its unique properties. The device is capable of providing increased efficiency and accuracy in a wide range of applications, while also being strong enough to withstand a range of environmental and operating conditions. In conclusion, the PIMC31,115 is a highly reliable, efficient, and easy-to-use pre-biased transistor array.
