This is an important characteristic. A diode can be thought of as a one way check valve. Meter Check Of A Diode Diodes And Rectifiers Electronics What Is A Protection Diode How Does A Diode And Led Work Eagle Blog If you give positive voltage to the p side and negative voltage to the n side the electrons in the n side will want to go to the positive voltage at the p side and the holes of the p side will want to go to the negative voltage at the n side. Diode negative and positive side . The positive side of the diode that is the lead attached to the p type semiconductor is called the anode. When the probes are reversed the zener diode will not conduct. The diode is an electronic component that only permits electricity to flow in one direction while preventing potentially harmful reversals from reaching the sensitive circuit. Function of a diod...
