The working principle of the PEMH4,115 power transistor arrays is based on the basic principle of operation of bipolar junction transistors (BJTs). It consists of four transistors connected in common-base current gain configuration. It is operated in such a way that the current in the emitter-collector paths remains constant and only the collector current is modified to obtain higher gain. The device is pre-biased to be operated in the saturation region thus allowing for linear current amplification. The voltage applied to the base controls the current flow between the emitter and collector terminals. As the base current is increased, the current in the collector-emitter path is increased thereby increasing the output power.

In conclusion, the PEMH4,115 is a pre-biased, bipolar junction transistor (BJT) array which offers excellent performance characteristics and cost-effective operation in a wide range of applications. It has a high speed switching capability, superior thermal stability, smaller footprint and built-in protection features which make it ideal for use in various automotive, telecoms and industrial applications.
