摘要： In a power module (111), a free-wheeling diode (1A), an IGBT (1B), and a capacitor (20) for smoothing direct current are disposed directly on a surface (2BS) of a conductive heat sink (2B) with through holes (2BH). The rear electrodes of the free wheeling diode (1A), the IGBT (1B), and the capacitor (20) are bonded to the heat sink (2B) for example with solder, whereby the diode (1A), the IGBT (1B), and the capacitor (20) are electrically connected with the heat sink (2B). The front electrodes of the diode (1A), the IGBT (1B), and the capacitor (20) are connected with each other for example by wires (7). In the heat sink (2B), a cooling medium flows through the through holes (2BH). Such a configuration allows miniaturization of the power module and improves the cooling performance and reliability of the power module.

摘要： In a circuit board having four-layered conductive pattern on which a control circuit is arranged, wiring sub-patterns 133a in the first layer are divided into four areas A1-A3 and A8, for respective sets of circuit parts having same power potentials. Respective sub-patterns belonging to the areas A1-A3 are partially or fully surrounded by wiring sub-patterns PEa1 PEa3 connected to negative power potentials of circuit parts belonging to respective areas, respectively. Similarly, at least part of a wiring patten Pa2 for transmitting an input signal to a semiconductor active element is surrounded by a wiring pattern PEa4. Penetration of electric noises to the wiring patterns for the control circuit, in particular to the wiring pattern for transmitting the input signal to semiconductor element, is decreased to thereby prevent misoperation due to electric noises.

摘要： Respective side ends (20s, 1s) of a T.sub.1 electrode (20) and a gate electrode (1) of a TRIAC (70) are mutually adjacent and located on a P.sub.1 layer (13). The side ends (20s, 1s) are connected electrically by a resistance area (13a) which is made of the same material as a semiconductor material used to make the P.sub.1 layer (13). A gate current branches into first and second branch currents (I.sub.GT1, I.sub.GT2). Because the second branch current does not contribute to the turn on of the TRIAC, undesirable (dv/dt) turn on is prevented.
