(2) The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard, High-K board, as specified in JESD51-7, in an environment described in JESD51-2a. (3) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8. (4) The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDEC- standard test exists, but a close description can be found in the ANSI SEMI standard G30-88. (5) The junction-to-top characterization parameter, ΨJT, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining θJA, using a procedure described in JESD51-2a (sections 6 and 7). (6) The junction-to-board characterization parameter, ΨJB estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining θJA, using a procedure described in JESD51-2a (sections 6 and 7). 7.4 Thermal Information THERMAL METRIC(1) TEST CONDITIONS TCAN1042 UNIT D (SOIC) 8 Pins RθJA Junction-to-air thermal resistance High-K thermal resistance(2) 105.8 °C/W RθJB Junction-to-board thermal resistance(3) 46.8 °C/W RθJC(TOP) Junction-to-case (top) thermal resistance (4) 48.3 °C/W ΨJT Junction-to-top characterization parameter(5) 8.7 °C/W ΨJB Junction-to-board characterization parameter(6) 46.2 °C/W PD Average power dissipation VCC = 5 V, VIO = 5 V (if applicable), TJ = 27°C, RL = 60 Ω, STB at 0 V, Input to TXD at 250 kHz, CL_RXD = 15 pF.
