1. For a device surface mounted on 25mm x 25mm x 1.6mm FR4 PCB with high coverage of single sided 1oz copper, in still air conditions; the device is
measured when operating in a steady-state condition.
2. Same as note (1), except the device is measured at t
≤
10 sec.
3. Same as note (1), except the device is pulsed with D= 0.02 and pulse width 300 µs. The pulse current is limited by the maximum junction temperature.
4. Thermal resistance from junction to solder-point (at the end of the drain lead).
