Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To mount power semiconductor elements on a module substrate in the manner in which both the thermal balance and the heat dispersion of two power transistors are satisfied. SOLUTION: When power transistors 42, 43 are operated, heat is generated from the power transistors 42, 43. Since they are sufficiently small as compared with a module substrate 41, the heat diffuses in thermal diffusion regions 44, 45 at an angle 45 deg. to the surface of the module substrate 41 on which the power transistors 42, 43 are mounted. In this case, the mounting interval of the power transistors 42, 43 is (a), and the thickness of the module substrate 41 is (d). When the power transistors 42, 43 are mounted at an interval which satisfies a relation a=2×d, the thermal diffusion regions 44, 45 of the power transistors 42, 43 come into contact with each other, on the back of the module substrate 41 on which the power transistor 42, 43 are not mounted. Thereby the heat dispersion of the power transistors 42, 43 can be optimized while the thermal balance is maintained.
