Derating Curve

When the terminal temperature exceeds 140°C, power dissipation

must be adjusted according to the derating curves below.

When the ambient temperature exceeds 70°C, power dissipation

must be adjusted according to the derating curves below.

Design and specifications are subject to change without notice.

Carefully check the specification sheet supplied with the product before using or ordering it.
