provided for package comparison and printed circuit board
design considerations. Airflow measurements in
ply with JEDEC standards JESD51-2 and JESD51-6, and the
junction-to-board measurement complies with JESD51-8. The
junction-to-case measurement complies with MIL-STD-883
(Method 1012.1). All measurements use a 2S2P JEDEC
testboard.
