Electrical wiring device for providing variable power

A dimmer device with temperature compensation, comprising:

• a housing assembly including a line terminal configured to be attached to a mains input, and a load terminal configured to be attached to a load;
• a bridge rectifier, including a first input terminal and a second input terminal and a first output terminal and a second output terminal, wherein the first input terminal is electrically connected to the line terminal and the second input terminal is electrically connected to the load terminal;
• a field-effect transistor having a body diode, the field-effect transistor being connected between the first output terminal and the second output terminal such that the body diode blocks current between the first output terminal and the second output terminal except for when a sufficient voltage is applied to a gate of the field-effect transistor, wherein blocking current between the first output terminal and the second output terminal interrupts current to the load terminal;
• a thermally sensitive component disposed such that an electrical characteristic of the thermally sensitive component is representative of a temperature of the bridge rectifier;
• at least one variable control mechanism coupled to the housing assembly, the at least one variable control mechanism being configured to adjustably select a user adjustable load setting, the user adjustable load setting being adjustable between a minimum setting and a maximum setting;
• and
• a controller configured to apply a voltage to the gate of the field-effect transistor such that the field-effect transistor is on for an on-time occurring during at least a portion of each half cycle of the mains input, wherein the controller is configured to adjust the on-time of the field-effect transistor based, at least in part, on the user adjustable load setting, wherein the controller is further configured to reduce the on-time of the field-effect transistor when the electrical characteristic of the thermally sensitive component indicates that the temperature of the bridge rectifier exceeds a threshold.
