ABSTRACT:
A field replaceable silicon controlled rectifier (SCR) heat sink with reliable thermal and electrical connection to the SCR or other electronic device for an electronic circuit forming part of a vehicle control. The SCR heat sink includes two discrete heat sink blocks having opposed parallel faces between which an SCR or other electronic device may be properly clamped. At least one insulator hold down bar and an associated spring overlie a flange on the lowr end of each block and facilitate clamping the blocks to a base plate. The blocks are clamped to the SCR by a force distributing spring and bolts for properly applying a clamping force to the SCR or other electronic device.
