Twenty Rows' 2012 Cabernet Sauvignon was harvested in mid-to-late October from appelations across Napa Valley including Mt. Veeder, Coombsville, and Oak Knoll. The Cabernet Sauvignon fruit also includes 4% Petite Verdot, 4% Cabernet Franc, and 2% Malbec.
Zener diode is a diode which is used in its break down region. The diode is kept reverse biased in a circuit, and so it does not allow current to pass until the voltage is greater than the breakdown voltage of the zener.
Zener diodes have many of the same basic properties of ordinary semiconductor diodes. They conduct in the forward direction and have the same turn on voltage as ordinary diodes. For silicon this is about 0.6 volts. In the reverse direction, the operation of a Zener diode is quite different to an ordinary diode.For low voltages the diodes do not conduct as would be expected. However, once a certain voltage is reached the diode breaks down and current flows.iode Tutorial Includes: Diode types PN junction diode LED PIN diode Schottky barrier diode Varactor / varicap Zener diode. Zener diodes are a form of semiconductor diode that are widely used in electronics circuits as voltage references.
