Working Principle

The 1N2837RB is an electrically operated device consisting of a semiconductor PN junction. It works by connecting two opposite diodes together in parallel and utilizing the breakdown voltage. It consists of a cathode and an anode. The diode operates by allowing current to flow in one direction only. When the forward voltage applied to the anode is higher than its breakdown voltage, the current will be blocked and the diode will remain in a non-conductive state. However, when the reverse voltage is higher than the breakdown voltage, the diode will become forward biased and will allow current to flow in both directions. This allows the diode to regulate the voltage across itself, creating a constant voltage source.
