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.
1 In vacuum tubes (including cathode ray tubes) it is the negative terminal where electrons enter the device from the external circuit and proceed into the tube's near vacuum, constituting a positive current flowing out of the device.he flow of electrons is almost always from anode to cathode outside of the cell or device, regardless of the cell or device type and operating mode. An exception is when a diode reverse-conducts, either by accident (breakdown of a normal diode) or by design (breakdown of a Zener diode, photo-current of a photodiode).
