THERMAL CHARACTERISTICS
Table 32
JEDEC standards JESD51-2 and JESD51-6 and the junction-to-
board measurement complies with JESD51-8. Test board and
thermal via design comply with JEDEC standards JESD51-9
(mini-BGA) and JESD51-5 (integrated Heat Sink LQFP). The
junction-to-case measurement complies with MIL-STD-883.
All measurements use a 2S2P JEDEC test board.
Industrial applications using the mini-BGA package require
thermal vias, to an embedded ground plane, in the PCB. Refer to
JEDEC standard JESD51-9 for printed circuit board thermal
ball land and thermal via design information.
To determine the junction temperature of the device while on
the application PCB, use:
