Notes:
This section provides thermal management data for the 603R. This information is based on a
typical desktop configuration using a 240 lead, 32 mm x 32 mm, wire-bond CERQUAD package
with the cavity up (the silicon die is attached to the bottom of the package). This configuration
enables dissipation through the PCB.
The thermal characteristics for a wire-bond CERQUAD package are as follows:
Configuration
With 2328B heat sink
Characteristic
Junction-to-bottom of balls
Junction-to-ambient thermal resistance natural convection,
four-layer (2s2p) board
Junction to board thermal resistance
• Thermal resistance (junction to bottom of the case) (typical) = R
• Thermal resistance (junction to top of the case) is typically 16°C/W
Rsa (°C/W)
1. Simulation, no convection air flow.
2. Per JEDEC JESD51-2 with the board horizontal.
3. Per JEDEC JESD51-8 with the board horizontal.
