What are the different types of semiconductor products, and how are they used?
A1 The main semiconductor products are classified by function as follows. At NEC Electronics, we call communication devices and display/image processing devices “ASSP” (Application Specific Standard Product), and distinguish them from semi-custom ASIC (Application Specific IC). (1) Diode A diode is a rectifying device that lets the current flow only in one direction. However, if the rated voltage (breakdown voltage) is exceeded even in the opposite direction, the device changes to a conductive state and current flows through. For the operation of diodes, refer to the operating principles of semiconductor devices. (a) Rectifying diode A rectifying diode uses a rectifying function to obtain a direct current from an alternating current power supply. Here, in the case of one diode, for half-wave rectification not output on the minus side, a pulsating flow is output, and even if a smoothing capacitor is installed, the DC voltage fed to the load becomes lower.
