FDS6990AS Datasheet, PDF (3/8 Pages) Fairchild Semiconductor – Dual 30V N-Channel PowerTrench SyncFET

Notes:
1. R_θJA 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 the drain pins.
R_θJC is guaranteed by design while R_θCA is determined by the user's board design.
a) 78°C/W when mounted
on a 0.5 in² pad of 2 oz
copper
b) 125°C/W when
mounted on a 0.02 in²
pad of 2 oz copper
c) 135°C/W when
mounted on a
minimum pad.
