Working Principle
IC 2SD1047 is a NPN epitaxial planar bipolar transistors. The major advantage of the epitaxial transistor is virtual elimination of the series resistance of the collector, switching frequency of the device is also improved due to the use of epitaxial technique. To use the transistor as switch it has to be operated cut-off and saturation region of the device, however to use the transistor as amplifier it has to be operated in the active region of the characteristics curve.
Applications
IC 2SD1047 high power NPN transistor is widely used in the following applications
● Power supply
● Power amplifiers
● Fast electronic switching applications
Resistive load switching circuit
Circuit diagram of resistive load switching circuit is shown in figure below. When input signal is applied to the base of the of the transistor, emitter current flows. In the absence of signal at the base collector current will be zero.
Power Supply – Current Pass Circuit
Power supply- current pass circuit using IC 2SD1047 is shown in the figure below. Current pass circuit is the heart of every power supply circuit. Its function is to maintain constant voltage at the output regardless of the size of the load. Active elements that are used in the circuit are 9041, 2SD882 and 2SD1047.
