Title: Part No. 2SC945
Introduction:
N channel silicon power transistor is doped between P regions used for various purpose in different circuits. It is a three-terminal semiconductor switching device that can be used for fast switching and for traction control with high efficiency in many types of electronic devices. These devices are mostly used in amplifiers for switching/processing and complex wave patters with pulse width modulation (PWM) scheme.
Features:
Operate in high voltage
Excellent Linearity
Trench gate and thin wafer technology
Emitter to collector at maximum value is 600 V
Working:
To understand and to learn about the working boundary condition of the N channel silicon transistor , let assume a voltage source VG connected to the positively to the Gate terminal with respect to the Emitter of the N channel silicon transistor present for testing. Consider other voltage source VCC connected across The Emitter and the Collector, where Collector is kept positive with respect to the Emitter of the transistor. Since J2 is in reverse bias there will not be any current flow inside the silicon transistor (from collector to emitter) that is transistor.Initially, or first consider that there is no voltage applied or present to the Gate terminal, at this stage the silicon transistor will be in zero charge stage. Now if we increase the applied gate voltage, due to the capacitance effect on the SiO2 layer the negative ions will get accumulated or stored on the upper side of the layer.
Applications:
Used in Small Electronic Devices
Motor drives both AC & DC
Uninterruptable power supplies
Plasmas display panels
Control of traction motors
Find Interface – UARTs (Universal Asynchronous Receiver Transmitter),Interface – Voice Record and Playback on Utsource
