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 our testing, we could not find a Zener diode that would protect a laser diode. We even tried Transient Voltage Suppressor (TVS) devices whose function is similar to a Zener diode, but are made specially to protect electronic devices from power surges. However, we did not find any TVS devices that were effective at protecting laser diodes either.
