Abstract: A power array includes a plurality of FET power assemblies and each FET power assembly has at least one field effect transistor mounted to a ciruit board. The circuit boards are arranged atop each other. A power supply pin extends through the circuit boards and is connected to a power input of each field effect transistor. A power output of each FET power assembly is connected to a power output pin which extends through each of the circuit boards. A heat sink is mounted to the power array beneath the lowest FET power assembly and is thermally connected to the field effect transistors of each FET power assembly. A method of assembling a power array including a plurality of FET power assemblies with at least one field effect transistor.
