Diodes are electronic components that allow electrical current to flow in only one direction. Rectifiers are composed by several diodes that are used to convert alternating current into direct current. Single-phase rectifier bridges are made of four diodes connected in an Alternating Current (AC) to Direct Current (DC) circuit configuration. The BYS12-90HE3/TR is an example of a silicon bridge single-phase rectifier.

The BYS12-90HE3/TR rectifier bridges are designed to be used in low- and middle-power applications, such as Switch Mode Power Supplies (SMPS), Power Factor Correction (PFC) systems, and solar PV circuits. Besides, they can be used in variable-speed motor drives, battery-charging applications, and arc-welding machines.

The BYS12-90HE3/TR consists of four PowerMITE™ packages in a single compact surface mount case. This component is designed specifically for use in high-frequency switching applications as an alternate current to direct current converter. Its common features are:

• Forward voltage drop of 1.1 V at 10A;
• Repetitive peak forward voltage drop of 2.1 V at 10A;
• Low leakage current;
• High surge current capability.

The general working principle of all diodes, and therefore of rectifier bridges, is rather simple. The current flowing through a diode is determined by its voltage drop. In a single phase rectifier bridge, two opposite diodes switch simultaneously and the current direction is determined by the sign of the voltage at their common input terminal. The other two diodes remain reverse-biased and do not influence the current.

The BYS12-90HE3/TR rectifier bridge is ideal for applications when precise reverse voltage protection, such as motor control or solar energy storage, is required. It is ideal for environments where high voltage transients occur from time to time, such as isolated systems, telecom, and power supply applications. The reliable performance of the BYS12-90HE3/TR rectifier bridge will ensure long-term protection of sensitive electronics.

The BYS12-90HE3/TR is rated for continuous operation up to 90A at 100°C, and is capable of intermittent operation up to 150A. It is designed to be used in applications with a frequency range of up to 50 kHz, and can withstand a maximum peak reverse voltage of 800 V. The BYS12-90HE3/TR is also capable of high surge withstanding ratings, up to 146 A of peak forward current.

In summary, the BYS12-90HE3/TR silicon bridge single-phase rectifier bridge is appropriate for low- and middle-power applications that require precise reverse voltage protection. It is capable of operation at high frequencies, and withstands high surge withstanding ratings. It is highly reliable, durable, and simple to use.
