Having one of the most common ratings in the industry, the Fairchild FR306G B0G rectifier diode is one of the best-known and trusted components when process maintenance or new system construction requiring a single rectifier diode is necessary. With performances renowned for both dependability and consistency even in extreme conditions, the FR306G B0G rectifier diode is a key component in countless applications.

The FR306G B0G rectifier diode falls into the category of thermally-protected, single step, dual common anode Fast Recovery Rectifiers. It is designed for general-purpose use, with ratings of 600V, 3A, and approximately 0.6°C/W thermal resistance from junction to case. This makes it optimal for power supplies and other circuitry that require large current and low-losses, such as power rectifiers, polarity inverters, AC-DC power supply, large AC reactive power compensation, diode bridges, personal computers, etc.

The FR306G B0G rectifier diode may be one of Fairchild’s most widely used products, but its most significant advantage over other available rectifiers is its innovative design to ensure maximum protection against excessive temperature. Thermally Protected components protect circuits against thermal runaway, and are specifically designed to improve component longevity and reduce costly repairs of faulty components.

The FR306G B0G rectifier diode also inherently has a very low reverse current due to its fast recovery time, so it is able to recover quickly from any momentary over current as a result of a fault condition or surge voltage. The component’s high current rating, low thermal resistance, and fast recovery capabilities when combined make it an ideal choice for systems that carry large current loads or are susceptible to overvoltage conditions.

Knowing how it works is key to understanding the success of the FR306G B0G rectifier diode: in the forward direction, the diode conducts a large current and acts as a low-loss bridge between the anode and the cathode. In the reverse direction, minority carriers stored in the PN junction are subsequently depleted, generating a small reverse current. Due to its fast recovery time, the stored minority carriers cross from the cathode to the anode almost instantaneously and the reverse leakage current quickly decreases, allowing the component to operate with minimal loss.

The FR306G B0G rectifier diode is an integral part of secure, low-loss and long-term successful projects. Its advanced design to accommodate high currents and its ability to prevent thermal runaway make it the best choice for electronic systems in the power supply industry.
