Claim 18:
19. A bi-directional electronic solid-state switch assembly, comprising:
a base plate including a thermally conductive, electrically insulating layer and a direct bonded substrate affixed to the base plate;
a first terminal and a second terminal;
a plurality of power transistors electrically connected in parallel between the first and second terminals;
a plurality of gate drivers arranged to control the plurality of power transistors;
a communication interface, a current sensor, and a snubber circuit; and
a controller, the controller being in communication with the plurality of gate drivers, the current sensor, and the communication interface;
a thermally conducting, electrically insulating layer affixed to a bottom portion of the base plate and a direct bonded substrate affixed to the base plate; and
a heat exchanger coupled to a posterior of the thermally conducting, electrically insulating layer;
wherein the controller is configured to control, via the plurality of gate drivers, the plurality of power transistors; and
wherein the heat exchanger includes a plurality of pin fins protruding from a bottom portion of the thermally conducting, electrically insulating layer.
