Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

AD8051/AD8052/AD8054 is limited by the associated rise in

junction temperature. The maximum safe junction temperature

for plastic encapsulated devices is determined by the glass

transition temperature of the plastic, approximately 150°C.

Temporarily exceeding this limit can cause a shift in parametric

performance due to a change in the stresses exerted on the die

by the package. Exceeding a junction temperature of 175°C for

an extended period can result in device failure.

While the AD8051/AD8052/AD8054 are internally short-

circuit protected, this cannot be sufficient to guarantee that the

maximum junction temperature (150°C) is not exceeded under

all conditions. To ensure proper operation, it is necessary to

observe the maximum power derating curves.
