THERMAL CHARACTERISTICS
Table 38
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. All measure-
ments use a 2S2P JEDEC test board.
To determine the junction temperature of the device while on
the application PCB, use
