Inventor: TOPP RAINER DIPL ING
IPC: H03F3/343
Filed: 1989-08-16
Abstract: A Darlington transistor circuit comprises a power transistor T1 and a driver transistor T2 in a chip produced by planar technology. A metallized electrode coating (18) is provided on the space charge region formed in the region of the pn junction on the top surface of the chip between the base and the collector. A voltage distributor has a connection to the metallized electrode coating (18). The transistor turnover voltage UCE can be adjusted by means of the electric potential of the metallized electrode coating (18). This potential is governed by the setting of the voltage distributor. According to the invention, this adjustment potential, and hence the turnover voltage UCE, is controlled by an additional reference voltage. The turnover voltage is thereby stabilized and in particular essentially unaffected by temperature, long-term drift and assembly.
