PACKAGE DESCRIPTIO
and resulting in the IC’s junction temperature to rise
above 150°C, thus cutting off the base current to the PNP
transistor. This action will limit the transistor junction
temperature to a temperature well above 150°C. The
temperature depends on how well the IC and PNP are
thermally connected and on the transistor’s θ
JA
. See the
External PNP Transistor section for information on pro-
tecting the transistor from overheating.
