Provided is a circuit including a switching transistor having a control terminal configured to receive a control signal and having a current flow path therethrough. The switching transistor becomes conductive in response to the control signal having a first value. The current flow path through the switching transistor provides a current flow line between two nodes. In a non-conductive state, a voltage drop stress is across the switching transistor. The circuit comprises a sense transistor that is coupled to and a scaled replica of the switching transistor. The sense transistor has a sense current therethrough. The sense current is indicative of the current of the switching transistor. The circuit includes coupling circuitry configured to apply the voltage drop stress across the sense transistor in response to the switching transistor being non-conductive. In the non-conductive state, the voltage drop stress is replicated across both the switching transistor and the sense transistor.
