Fig 3. Maximum Effective Transient Thermal Impedance, Junction-to-Case „
ƒ Surface mounted on 1 in. square Cu board, steady state.
„ TC measured with thermocouple incontact with top (Drain) of part.
ˆ Used double sided cooling, mounting pad with large heatsink.
Notes:
‰ Mounted on minimum footprint full size board with metalized
back and with small clip heatsink.
Š Rθ is measured at TJ of approximately 90°C.
