 Surface mounted on 1 in. square Cu board, steady state.
 TC measured with thermocouple incontact with top (Drain) of part.
 Repetitive rating; pulse width limited by max. junction temperature.
 Used double sided cooling, mounting pad with large heatsink.
 Mounted on minimum footprint full size board with metalized
back and with small clip heatsink.
 R is measured at TJ of approximately 90°C.
 Surface mounted on 1 in. square Cu
