The Turbochef TBC100481 High Voltage Diode is an electrical component used in compatible commercial microwave cooking equipment. During operation, the diode permits current to travel primarily in one direction within the high-voltage circuit, supporting the voltage-conversion process associated with microwave generation. It works with other high-voltage components, including the transformer and capacitor, as part of the microwave power circuit. The diode is installed inside the oven’s electrical compartment and connects to the high-voltage circuit through its designated terminals.
