Notes:
1. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
2. The case-to-ambient thermal resistance is measured in a JEDEC JESD51-6 standard environment; and may not accurately predict
thermal performance in production equipment environments. The operational case temperature must be maintained.
3. Modeled on standard JEDEC 2S2P card, 50x50mm
