<p>In a circuit for the discharge protection of a passive current source (7) a load (4, 5) is fed via the emitter collector circuit of a transistor (13), the basis of said transistor (13) being connected to a zener diode (15) via a resistor (16), the joint point of the resistor (16) and the zener diode (15) being connected to the current source (7) via a resistor (14). Thus a simple and effective cutting out of the load (4, 5) is achieved, when the voltage of the current source (7) falls below a threshold value determined by the zener diode (15). </p> |
