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
Scale 1 : 1 on letter size paper
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.
