Datasheet search engine - 350 million electronic component datasheets from 8500 manufacturers. A diode is an electronic component with two electrodes (connectors) when voltage goes between the gate and the cathode the lower transistor will turn on. At first glance, the nand version shown on the left should eliminate this problem any logic 0 input will immediately pull the transistor base down and turn the. P517/617 lec5, p1 diodes and transistors diodes • what do we use diodes for protect circuits by limiting the voltage (clipping and clamping) turn ac into dc. Diodes – a transistor is a semiconductor device, just like a diode in a way, it’s what you’d get if you stacked two diodes together, and tied their anodes.
To better understand the difference between the two, let us revisit diodes for a moment like diodes, transistors are made up of configurations of pn junctions.
