Absolute maximum ratings
Thermal resistance
NOTES:
(a) For a device surface mounted on 25mm x 25mm FR4 PCB with high coverage of single sided 1oz copper, in still air
conditions.
(b) For a device surface mounted on FR4 PCB measured at t≤ 5 sec.
(c) Repetitive rating - 25mm x 25mm FR4 PCB, D=0.02, pulse width 300μs - pulse width limited by maximum junction
temperature.
(d) Thermal resistance from junction to solder-point (at end of drain lead).
