Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. TA = 25°C, unless otherwise specified.

Notes:
5. Non-repetitive rating: Pulse width is limited by maximum junction temperature.
6. L = 51mH, starting TJ = 25°C.
Thermal Impedance
TA = 25°C, unless otherwise specified. All items are tested with the standards JESD 51-2 and 51-10 (DIP).
