IRF230; 200V Single N-Channel Hi-Rel MOSFET in a TO-204AA package
2N6758 Maximum Drain Current vs Case Temperature
Use the graph to determine how to derate a 2N6758 based on Drain current and maximum case temperature. The chart is based on still air [free air]. With out forced air cooling the maximum drain current for the 2N6758 is 9 amps at 250C. Decrease the maximum drain current with increasing temperature as depicted in the chart. Never exceed a junction temperature of 150C or damage will result. Consult a data sheet for additional specifications.
2N6758 Maximum Ratings

FET Derating Compensation, Transistor Derating Guidelines
TO-204 Case mount. The 2N6758 uses a diamond shape flange to achieve thermal management of the case temperature, by providing a large metal surface to act as either a dissipator of heat or as an attachment point to a larger heat sink. The Drain is electrically connected to the case.
