A semiconductor switch device according to one or more embodiments may include a main switch that switches power supplied from a power supply, a driver that outputs a voltage lower than that of normal operation so that the main switch is in a constant voltage regulation state in case of a power short detection operation, a controller that controls a normal operation or a power short detection operation of the driver, a power short detector that detects if an output voltage has a sufficient potential difference with respect to a power supply voltage in the case of the power short detection operation, and a diagnostic circuit that diagnoses the power short and outputs a diagnostic result in response to detecting that the output voltage does not have a sufficient potential difference with respect to the power supply voltage in the case of the power short detection operation of the driver.
