Thermal Resistance Junction to Lead 3/8" = 30.0ēC/W
RθJL = 30.0°C/W
NOTES:
1. This is the true inverse of the worst case thermal resistance value. All devices are capable of operating ≤ TJ
specified on this curve. Any parallel line to this curve will intersect the appropriate power for the desired
maximum TJ allowed.
2. This temperature-current derating curve varies with applied voltage.
