Electrical Characteristics
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 25˚C, the device must be derated based on a 150˚C maximum junction temperature and a thermal resistance of
Note 4: Human body model, 100 pF discharged through a 1.5 k
Note 5: Typicals are measured at 25˚C 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 V
