maximum is ±16V.
3. For a device surface mounted on 50mm x 50mm x 1.6mm FR4 PCB with high coverage of single sided 2oz copper, in still air conditions; the device is
measured when operating in a steady-state condition.
4. Same as note 3, except the device is measured at t ≤ 10 sec.
5. Same as note 3, except the device is pulsed with D = 0.02 and pulse width 300µs. The pulse current is limited by the maximum junction temperature.
6. 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.
7. Thermal resistance from junction to solder-point (at the end of the drain lead).
