• Manufacturer: ON Semiconductor

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
Specific notes on thermal characterization conditions:
All boards are 0.062” thick FR4, 3” square, with varying amounts of copper heat spreader, in still air (free convection) conditions. Numerical
values are derived from an axisymmetric finite-element model where active die area, total die area, flag area, pad area, and board area are
equated to the actual corresponding areas.
1. 1 oz copper, 6 x 9 mm, 0.062” thick FR-4.
2. 1 oz copper, 645 mm
3. 1 oz copper, 17.2 mm
4. “board” is defined as center of exposed pad soldered to board; this is the recommended number to be used for thermal calculations, as it
