Zener Diode 6 Volt 0.25Watt
diode allows current to flow from its anode to its cathode like a
normal semiconductor diode, but it also permits current to flow in the
reverse direction when its "Zener voltage" is reached. Zener diodes have
a highly doped p-n junction. Normal diodes will also break down with a
reverse voltage but the voltage and sharpness of the knee are not as
well defined as for a Zener diode. Also normal diodes are not designed
to operate in the breakdown region, but Zener diodes can reliably
operate in this region.
This is a 6 Volts 0.25 Watt Through Hole Zener diode.
