<p>PURPOSE:To miniaturize a module with easier parallel connection by housing two power transistor composites into a common container in such as specified arrangement that electrode terminals are led out to the top thereof. CONSTITUTION:For example, two composites composed of power transistor chip connected to a feedback diode and a resistance and a diode chip in a Darlington connection are housed in a package 15 having a metal base plate 13 by way of insulating plates 11a and 11b. Electrode terminals of the composites are led to a fixed position at the top of a container through a printed board 14 supported by collector lead terminals 1a and 1b. Collector terminals 1a and 1b with the tip bent and emitter terminals 9a and 9b are arranged at a specified space on the top of the this module 100 sealed with a resin 16. Base terminals 10a and 10b and emitter auxiliary terminals 18a and 18b are at the end thereof. Thus, the use of the bars 19-22 facilitates the parallel connection of a pluality of modules while enabling smaller size configuration because of easier assembly.</p> |
