Notes :
a.Repetitive Rating : Pulse width limited by maximum junction temperature.
b.Surface Mounted on FR4 Board, t < 10 sec.
c.Pulse Test : Pulse Width < 300µs, Duty Cycle < 2%.
d.Guaranteed by design, not subject to production testing.
.
e.RθJA is the sum of junction-to-case-ambient thermal resistance where the case tmermal reference is defined
as the solder mounting surface of the drain pins. RθJc is guaranteed by design while RθJA is determined by
the user's board design
