OUTPUT STAGE FEATURING ZENER VOLTAGE BALANCING

摘要

The invention relates to an output stage, especially a switching output stage (10) for switching inductive loads (4), comprising several individual output stages that are connected in parallel and are provided with degenerative transistors (1), in the degenerative path of which one respective Zener diode (2) is supplied. The electric power during a switching-off process can be distributed in a particularly equal manner to the individual output stages or transistors (1) by disposing the Zener diodes (2) near the associated transistors (1a, 1b) such that the individual output stages are thermally coupled to the respectively associated transistor (1a, 1b) while the Zener voltage thereof increases as the temperature rises.
