resulting in the IC’s junction temperature to rise above
150°C, thus cutting off the PNP’s base current. This
action will limit the PNP’s junction temperature to some
temperature well above 150°C. The temperature
depends on how well the IC and PNP are thermally
connected and on the transistor’s θ

. See the External
PNP Transistor section for information on protecting the
transistor from overheating.
