High current high power solid state relay

A solid state relay (SSR) package comprising:

• a cover portion and a bottom case portion defining a hollow interior for receiving a solid state relay;
• the cover portion and the bottom case portion in thermal conductive contact with the solid state relay and configured to dissipate heat generated in an operation of the solid state relay;
• the solid state relay comprising:
• a source bus and a drain bus;
• a plurality of solid state switches arranged to switch power to the source bus from the drain bus;
• and a control circuit for controlling a gate terminal of the plurality of solid state switches;
• each solid state switch of the plurality of solid state switches comprising a source terminal, a drain terminal and a gate terminal, the plurality of solid state switches arranged in two rows;
• wherein all of the source terminals are conductively attached to the source bus and all of the drain terminals conductively attached to the drain bus;
• and the gate bus in electrical communication with the control circuit;
• the drain bus having a pair of side bus drain members including a left drain bus member and a right drain bus member, the side bus drain members extend parallel to left and right sides of source bus and are coplanar with the source bus, the side bus drain members connected with a drain bus connector member by a crossover member;
• the source bus and the drain bus are positioned in a single layer;
• the gate terminal operable to open and close a power flow through the plurality of solid state switches in response to a signal from the control circuit;
• and the source bus electrically isolated from the drain bus when the plurality of solid state switches is controlled by the gate terminal to an open state;
• the source bus in electrical communication with the drain bus when the plurality of solid state switches is controlled by the gate terminal to a closed state.
