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.
A real voltage regulatorwill have a finite source resistance. In the case of a Zener diode shunt regulator theeffective source resistance isÜ´ à¯ =Ü¸ à¯ @Ü« à¯à¯à¯à¯à¯ âÜ¸ à¯ @Ü« à¯à¯à¯¢à¯ª Ü« à¯à¯à¯à¯à¯ âÜ« à¯à¯à¯¢à¯ª (1)where I Zhigh and I Zlow are two distinct current levels within the operating region of theZener diode.ener Diode Voltage Regulators 2The forward bias region of a Zener diode is identical to that of a regular diode. In thereverse bias condition the Zener diode is an open circuit and there is only a small leakagecurrent in the microampere range.
