MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

ADEL2020 is limited by the associated rise in junction tempera-

ture. For the plastic packages, the maximum safe junction

temperature is 145

°C. If the maximum is exceeded momen-

tarily, proper circuit operation will be restored as soon as the

die temperature is reduced. Leaving the device in the over-

heated condition for an extended period can result in device

burnout. To ensure proper operation, it is important to observe

the derating curves in figure 4.

While the ADEL2020 is internally short circuit protected, this

may not be sufficient to guarantee that the maximum junction

temperature is not exceeded under all conditions.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although the

ADEL2020 features proprietary ESD protection circuitry, permanent damage may occur on devices

subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended

to avoid performance degradation or loss of functionality.
