Absolute maximum ratings

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

Յ5 sec.

(c) Repetitive rating - 25mm x 25mm FR4 PCB, D=0.02, pulse width 300

␮s - pulse width limited by maximum junction

temperature.
