Note 1: All voltages are measured with respect to the GND pin (4), unless otherwise specified.
Note 2:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits.
Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guar-
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is
given, however, the typical value is a good indication of device performance.
Note 3: For operating at case temperatures above 25C, the device must be derated based on a 150C maximum junction temperature and a thermal resistance of
θJC = 2C/W (junction to case). Refer to the section Determining the Maximum Power Dissipation in the Application Information section for more information.
Note 4: Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 5: Typicals are measured at 25C and represent the parametric norm.
Note 6: Limits are guarantees that all parts are tested in production to meet the stated values.
Note 7: The TO-263 Package is not recommended for VS > 16V due to impractical heatsinking limitations.
