Notes:
1. R
θ
JA
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
θ
JC
is guaranteed by
design while R
θ
CA
is determined by the user's board design.
Scale 1 : 1 on letter size paper
2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%.
