Transistors - Bipolar (BJT) - Arrays

The MMDT3906V-7 is a special-type of bipolar transistor array, with the specific arrangement of pairs of transferred emitters. It is designed for application in low voltage, medium-power, integrated circuits and other sub-circuits which require a low-power configuration.

Application Field

The MMDT3906V-7 is particularly suited for use in switching and amplifier circuits. Since it operates in low voltage, it is suitable for use in a wide range of equipment and systems, including industrial, telecom, automotive and power electronics. Since it is composed of a pair of emitter-coupled transistors, it has excellent thermal performance and is extremely reliable.

The MMDT3906V-7 is particularly adaptable in a wide range of cellular, telecom, and automotive applications. It is quite useful in implementations with high frequency switching as it offers good performance in high current applications even with high voltage disturbances. Its ability to work with low voltages also makes it well-suited for low power requirements, such as for low power amplifiers.

Working Principle

The MMDT3906V-7 is a two stage bipolar transistor array, with a pair of transferred emitters. It consists of two bipolar NPN transistors placed back to back. Each internal transistor consists of a pair of emitters, a collector-emitter path, and a base-emitter path.

The MMDT3906V-7 functions in a manner similar to that of a conventional NPN bipolar junction transistor (BJT). In operation, current passes through the base-emitter path, which causes a voltage drop between the base and the emitter. When this voltage reaches a certain level, the transistor “turns on” and allows current to pass from the collector to the emitter.

The MMDT3906V-7’s pair of transferred emitters is a unique feature which makes it especially efficient in applications that require a low power configuration. The two emitters are connected in parallel, with each emitter capable of supplying a unique current to the corresponding collector. This allows a greater current to pass through the circuit than could be achieved with a single emitter.

Additionally, since each of the two transistors is connected internally, they can be used to amplify or switch signals at high speeds. This is especially useful in applications that require low voltage devices, such as radiofrequency circuits or logic circuits.

Conclusion

The MMDT3906V-7 is a special type of bipolar transistor array with a pair of transferred emitters. It is designed specifically for low voltage, medium-power integrated circuits and other sub-circuits, allowing for efficient and reliable operation. Its pair of transferred emitters allows for greater current flow through the device, and it can be used in high speed, low voltage applications such as radiofrequency circuits and logic circuits.
