Diodes & Rectifiers

P-Q1N53X Diode - Zener, 5 Watt, ±5% tolerance
5W zener diodes that are great for use in tube amps. These are commonly used to drop B+ voltages for tube modification compatibility or to create low power modes for the amp. A zener is 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.
