Symbol Parameter Typical Value Unit θ JC Junction-to-Case Resistance (Note 4) TO-263-5 TO-252-4/TO-252-5 4 5 oC/W Note 3 : θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air. The sizes of the rectangular plane, where the devices are mounted, are shown in the table. Note 4: The case temperature is measured on the TAB of the device mounted on the test board described in Note 3 except the package TO-220-5. The case temperature of the TO-220-5 is measured on the bottom of the case directly below the die. APL1581 Symbol Parameter Test Conditions Min. Typ. Max.
