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 zener must be added to the gate of a MOSFET if the gate voltage comes from a supply that is above 20v. A normal transistor is a current amplifying device. For a load current of 100mA, the base current for a BC547 will need to be about 1mA. This means it has a current gain of about 100.
