(1) Refers to a case temperature at the measurement point described in Figure 3-1, below.

(2) Refers to steady-state thermal resistance between the junction of the built-in transistors and the case. For transient

thermal characteristics, see Section 15.1.

(3) Refers to steady-state thermal resistance between the junction of the built-in freewheeling diodes and the case.
