Diode - 1N4742A, 12V, Zener, 1W, 5% Tolerance
1N4742A 12V zener diode in a DO-41 package. A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.
