Diode Zener ZMM8.2V 0.5W MINIMELF
A Diode Zener ZMM8.2V 0.5W MINIMELF is a particular type of diode that, unlike a normal one, allows current to flow not only from its anode to its cathode, but also in the inverse direction, when the Zener voltage is reached. Zener diodes have a highly doped p-n junction. Normal diodes will also break down with a inverse 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.
Silicon Planar Zener Diodes
In Mini-MELF case especially for automatic insertion.
The Zener voltages are graded according to the international E 24 standard. Smaller voltage tolerances and other Zener voltages are available upon request.
These diodes are also available in DO-35 case with the type designation ZPD1 … ZPD51.
