(1) 125°C operating junction temperature is used for power rating calculations
(2) The range of values indicates the effect of pc-board. These values are intended to give the system designer an indication of the best
and worst case conditions. In general, the system designer should attempt to use larger traces on the pc-board where possible in order
to spread the heat away form the device more effectively. For information on the PowerPAD™ package, refer to Technical Brief,
PowerPad Thermally Enhanced Package, Texas Instruments (SLMA002) and Application Brief, PowerPad Made Easy, Texas
Instruments (SLMA004).
(3) The PowerPAD™ is not directly connected to any leads of this package. However, it is electrically and thermally connected to the
substrate which is the ground of the device.

NOTE: The 10% and 90% thresholds depict the dynamics of the BiPolar output devices that dominate the power MOSFET
transition through the Miller regions of operation.
