WebThe JESD51-8 standard requires that the metric be measured on a 2s2p board defined in JESD51-7, 9, 10, or 11. Measurement of the board temperature very close to the edge of the package body is also intended to minimize the contribution from the board. Further details are available in JESD51-8. 4.2 Junction-to-case thermal resistance (θJCtop) Web2.1.2 K FACTOR CALIBRATION Once the proper value of IM is selected, the relationship between the temperature sensing diode forward voltage and junction temperature is …
