The "T3" suffix refers to an 8 mm, 13 inch reel. For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. FR-5 = 1.0 X 0.75 X 0.62 in. 2. Alumina = 0.4 X 0.3 X 0.024 in, 99.5% alumina. DEVICE MARKING INFORMATION See specific marking information in the device marking column of the Electrical Characteristics table on page 3 of this data sheet. Devices listed in bold, italic are ON Semiconductor Preferred devices. Preferred devices are recommended choices for future use and best overall value.
