Diode Operating in Oil

For a diode operating in oil, the heat generated in the diode will mostly be dissipated to the oil through the leads of the diode. A small percentage of the heat will also be dissipated to the oil through the body of the diode.

The zero lead length thermal impedance, as specified in the catalog pages for the diode, can be used as a maximum thermal impedance from the diode to the oil. The diode junction temperature rise over the oil temperature will be equal to the power dissipated in the diode multiplied by the thermal resistance of the diode to the oil.

Typically, oil operation provides a very good method of removing the heat from the diode.
