BZV55C15 15V Zener Diode 500mW 5% Tolerance SOD80 Package MAX487 low-power RS-485/RS422 transceiver the rotor speed and gridThis is the BZV55C15 Zener diode. A Zener Diode is a semiconductor device that is used to conduct current either in the forward or reverse direction. The diode consists of a special, heavily doped p n junction, designed to conduct in the reverse direction when a certain specified voltage (Zener voltage) is reached. Every Zener diode has a well defined reverse breakdown voltage after which it starts conducting current in reverse bias mode without
