Working Principle

N-Channel BJT arrays, such as the DMG264050R, are composed of two transistors, a pnp and an npn transistor, with a common collector connection. The two transistors are connected in a complimentary manner, with the collector of the npn transistor connected to the collector of the pnp transistor. When a current is passed through the base of the npn transistor, it will activate, allowing for current to pass from the collector to the emitter, thus allowing for current flow. It is this principle which allows for the DMG264050R to be used in a wide range of applications.

Conclusion

The DMG264050R is a high power BJT array from ROHM, which can be used across a variety of applications, due to its wide operating range. The device is composed of two transistors, which act in complimentary manner, allowing for current flow to the emitter. This makes the DMG264050R a suitable choice for radios, amplifiers, power supplies and general power switching applications.
