Notes:
1. R
is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
θJA
the drain pins. R
a.) 170°C/W when mounted on a 1 in2 pad of 2 oz. copper.
b.) 260°C/W when mounted on a minimum pad.
2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%
is guaranteed by design while R
θJC
is determined by the user's board design.
