How to make negative 6V, 12 amp power supply using BD711 transistor |LM7906

5v fixed 12A negative power supply regulator.

It is a -6V Negative Voltage Regulator power supply. This is the circuit diagram. In this circuit, an input negative voltage of -12V is used with an output negative voltage of -6V. This power supply can drive negative 6v, 12amp(max), and 75-watt(max) devices. It can be used as a 75-watt (max) device. This power supply uses a voltage regulator LM7906 and BD711 NPN Transistor. DC to DC voltage can be converted through this circuit. This is called a stop-down negative power supply.

  1. BD711 Transistor
  2. NPN transistor

    Transistors are electronic parts. this component amplifies or modifies electrical signals or power in circuits. It is made of semiconductor material. two sorts of transistors of n-type or p-type. It works relying upon the electric flow. Transistors have three terminals: emitter, collector, and base (or source, drain, and gate). By applying a little voltage or current to the base (or gate), the transistor has some control over the progression of current between the emitter(or source) and collector (or drain).

    BD711 transistor

    NPN transistors are made of silicon or germanium semiconductor materials. When a p-type semiconductor element comprises two n-type semiconductor elements, it is called an NPN transistor. Shows an NPN transistor consisting of a layer of p-type material sandwiched between two layers of n-type material. NPN transistor has three terminals: emitter, base, and collector.

    BD711 pinout Transistor

    The BD711 is an NPN Transistor. When the base pin is grounded, the collector and emitter pins are open (reverse biased). When a positive voltage is applied to the base pin, the collector and emitter pins will be closed (forward-biased). It is a bi-polar NPN transistor. This component has a maximum collector current (IC) of 12A, an emitter-base voltage (VBE) of 100V, a base current (IB) of a maximum of 5A, and a maximum of 75 watts, and a Collector peak current of 18amp.
