A mounting clamp including heat sinks for a compression mounted type power semiconductor device such as an SCR, rectifier diode, or the like. Diamond shaped, tapered springs distribute the stresses equally throughout their lengths to afford greater deflection that reduces tolerances and facilitates staying within the allowable pressure range. A unitary spring subassembly also holds the pressure bearing and the load indicator. The construction is such that if the various parts become tilted on the pressure points, the line of force will still be through the center of the silicon disc inside the SCR. A pressure plate provides an enlarged base to afford low unit pressure on the insulation. Insulated parts afford the required electrical clearances. A dust-tight insulating cover or "boot" performs sealing, positioning and insulating functions during use and may also serve as a cushioned packing during shipment.
