The G2SBA60-M3/51 is a bridge rectifier diode commonly used in power supply circuits. This diode bridge is rated at 600V with a 50A peak forward surge current (IFSM). Its package has size of 32mm x 25mm and contains four 1N4007 diodes that are internally connected to form the bridge rectifier circuit.

Bridge rectifier diodes, such as the G2SBA60-M3/51, are used to transform an alternating current (AC) input into direct current (DC). Rectifier diodes are also used in inverters, which convert DC current back into AC. The G2SBA60-M3/51 bridge rectifier consists of two or four diodes connected in a bridge configuration which allows for bi-directional current flow and increases the peak inverse voltage (PIV) rating. This diode bridge is best suited for systems which require high surge current, such as motor-control circuits and uninterruptible power supplies.

The working principle of the G2SBA60-M3/51 bridge rectifier is simple. When connected to an AC source, the diodes will conduct current only when the voltage polarity across it is positive. This alternating action of conducting and non-conducting states translates to the output of a DC voltage. As the AC input alternates, the diodes alternate between conducting and non-conducting, producing a controlled pulse of current that accumulates to form a DC output. The output from this rectifier can then be regulated with a DC power supply or a DC-DC converter. Without a regulator, the output voltage would be a full-wave rectified version of the AC input voltage, ~1.4 times greater than the peak voltage of the AC source. In order to bridge the gap between the varying input AC voltage and the desired DC output, an AC-DC transformer and filter capacitor are often included as part of the power supply circuitry. The G2SBA60-M3/51 bridge rectifier can be used in a wide range of application areas such as aerospace, military and industrial. Its high surge current means it can be used in power supplies that draw significant amounts of current during start-up. As the surge current requirement decreases, other bridge rectifier diodes such as the G2LBA10 Series with a 40A surge current can be used.
