Introduction

The 1N4933RLG is a rectifier diode that acts as a two-way bridge between AC and DC power supplies. It has a peak reverse voltage of 1000V, a continuous forward current of 1A and a peak forward current of 3A. It is short-circuit protected and is suitable for both full-wave and half-wave rectification.

Applications

The 1N4933RLG is suitable for a wide range of applications, including AC to DC power supplies, solenoid/motor controls, voltage stabilization, and pulse generation. It is often used in power circuits, full-wave bridges, convirts, motor starter circuits, process controls, medical electronics, and electronic ballasts.

Working Principle

The 1N4933RLG is a monolithic bridge rectifier diode. It has two anode (positive) terminals and two cathode (negative) terminals. When a AC power supply is applied to the anode terminals, the diode will display a highly efficient non-linear conduction characteristics, and current can flow from the anode to the cathode. When the applied voltage reaches a peak voltage, the diode will become reverse biased and will no longer conduct current. This effect is known as full-wave rectification.

In the case of half-wave rectification, the applied voltage consists of only one half of an AC cycle, with the negative half of the wave blocked due to reverse biasing. This means that only one of the anode terminals is actually conducting. The 1N4933RLG is capable of withstanding the reverse bias generated by the blocked half-wave, thus allowing it to effectively block DC from crossing from one side to the other.
