MAT01GH

MAT01GH is a transistor array typically used for digital circuitry applications. It consists of four independent NPN transistors, each with a built-in dual collector for increased current capacity, and three independent complementary PNP transistors. The MAT01GH is manufactured using high-voltage semiconductor epitaxial chip technology, featuring two rows of complementary transistors with a total of 36 active elements. It also provides a wide range of performance parameters, including high gain (current gain hFE = 50 to 150), low saturation voltage (VCE(sat) = 0.2 V max), and a low collector-emitter saturation voltage.

Each of the four NPN transistors possess a dual collector design with two base terminals – the control base (CB) and the emitter base (EB). The control base is connected to the emitter terminal and works together with the emitter base to regulate and switch the current flow. The transfer response is optimized by adding a resistor between the CB and EB terminals. The PNP transistors each have one collector and two base terminals – the supply base (SB) and the emitter base (EB). The SB is a diode-connected terminal which helps reduce the voltage between the EB and collector during operation. Both the NPN and PNP transistors have an integrated diode to facilitate reverse polarity.

MAT01GH transistors can be used in various digital applications, such as logic circuits, signal switches, memory devices, and amplifiers. When used in logic circuits, the MAT01GH provides low current operation, low noise, and high switching speed. In signal switches, the fast transfer response combined with a wide variety of available output resistances allow fast and reliable switching. In memory devices, the MAT01GH transistor array is ideal for low-power and high-speed operations, while allowing efficient current flow.

The working principle of the MAT01GH transistor array is based on the current-voltage relationship of the NPN and PNP transistors. When the emitter-base junction of the NPN or PNP transistors is forward biased, electrons flow from the emitter to the collector, resulting in current flow. The amount of current flow depends on the applied base current. As the current increases, the voltage at the collector decreases, when the base current is removed, the collector voltage slowly increases until it reaches the voltage of the positive supply. Conversely, when the base-emitter junction of the NPN or PNP transistors is reverse biased, the current flowing between the collector and emitter ceases, resulting in a state called ‘cut-off’. When a voltage is applied across the collector-emitter terminals, the current will flow in the reverse direction, as long as the voltage is greater than the saturation voltage.

In summary, the MAT01GH transistor array is well-suited for digital applications due to its low voltage and high current capabilities, low noise and fast switching response, low saturation voltage, and wide range of output resistances. It is also ideal for memory devices and amplifiers. By understanding the working principles of the NPN and PNP transistors and their current-voltage relationship, the MAT01GH can easily be used in a variety of applications.
