Microsoft RB238T100 is a bridge rectifier array integrated circuit, which is a type of diode that can convert alternating current (AC) to direct current (DC). It has four independent reverse-polarity rectifier diodes, connected in a bridge configuration, which allows it to handle AC power from a single or multi-phase source. The circuit is rated for an output current of 1A and a maximum reverse voltage of 250V AC or DC.

Application Field

Microsoft RB238T100 is a popular solution for power supply and battery charger applications, such as AC/DC power supplies and adapters, dimmers, automotive and industrial equipment. The 1A current rating is ideal for low-power applications. It can also be used in other applications where high peak director current ratings are required, such as solar panel charge controllers and motor drive controllers.

Working Principle

Microsoft RB238T100 is an AC-to-DC converter circuit, which uses four independent rectifier diodes connected in a bridge configuration. The diodes form a bridge that allows current to flow in a single direction, while blocking the back flow of current. When AC input voltage is applied to the two ends of the bridge, the diodes conduct current from the lower voltage side to the higher voltage side, thus converting AC to DC. The DC output voltage will be equal to the peak AC input voltage minus the forward voltage drop of the diodes.

The RB238T100 is designed for use in applications that do not require a surge protection circuit. Therefore, it will maintain its rated performance without additional components. The circuit also includes an integrated reverse-current protection mechanism to protect against damage due to external power sources, such as battery discharges.

Additionally, the circuit is designed to operate over a wide temperature range of -40°C to +105°C, making it suitable for use in extreme temperatures and environments. The circuit is also designed to withstand transients and overemphasized electrical stresses.

Conclusion

Microsoft RB238T100 is an integrated bridge rectifier array that offers a solution for AC-to-DC conversion in low-power applications. The circuit features four reverse-polarity rectifier diodes that allow it to accurately convert AC power to DC. Additionally, the circuit is designed to operate over a wide temperature range and has integrated reverse-current protection to protect against external sources. The circuit is rated for a maximum output current of 1A and a maximum reverse voltage of 250V AC/DC, making it suitable for power supplies, adapters, dimmers, and other low-power applications.
