Working Principle of the ND471821

The ND471821 is an electronic switch composed of an anode, cathode and gate terminals. The anode is the positive terminal of the device, and the cathode is the negative terminal. The gate terminal is the control terminal and it is necessary to control the device. The operating principle is based on the PN junction of the device. When a positive voltage is applied at the gate terminal, the potential barrier between the anode and the cathode is lowered allowing the current to flow from the anode to the cathode. The current flow is then regulated by the voltage shown at the gate terminal. The ND471821 is able to withstand large currents and is the ideal switch device for high current applications.
