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.
In many ways the Silicon Controlled Rectifier, or the Thyristor as it is more commonly known, is similar to the transistor. It is a multi-layer semiconductor device, hence the âsiliconâ part of its name.It requires a gate signal to turn it âONâ, the âcontrolledâ part of the name and once âONâ it behaves like a rectifying diode, the ârectifierâ part of the name.In fact the circuit symbol for the thyristor suggests that this device acts like a controlled rectifying diode.owever, unlike the diode which is a two layer (P-N) semiconductor device, or the transistor which is a three layer (P-N-P, or N-P-N) device, the Thyristor is a four layer (P-N-P-N) semiconductor device that contains three PN junctions in series, and is represented by the symbol as shown.
