SBR20M45D1Q-13

Introduction

The SBR20M45D1Q-13 is a single-phase bridge rectifier module with double diodes connected in an anti-parallel configuration. This module is rated at an average current of 45A and a peak current of 63A, with a maximum forward voltage drop of 1.75V (at 45A).

Application Field and Working Principle

The SBR20M45D1Q-13 is primarily used in power supplies and AC power conversion applications, such as AC-DC rectification, AC-DC inversion, and DC-DC conversion. This module is well suited for applications where high-current rectification is required, as it allows for a high amount of current to be rectified with a low amount of power dissipation.

The module is composed of two diodes that are connected in an anti-parallel configuration. This is to enable the device to both rectify current from AC to DC and also act as an unidirectional pass gate for AC to DC applications. The two diodes are connected in such a way that when the AC source voltage exceeds the junction forward voltage drop of the diodes, current passes through the diodes and is rectified to a DC voltage. The rectified DC voltage is then filtered to remove rippled ripple noise and smoothed to a constant output voltage.

The module is also capable of operating as a voltage doubler, by using two anti-parallel diodes to pass AC voltage through and rectify it to a DC voltage which is then passed between the two diodes to be divided into two separate DC outputs.

Advantages

The SBR20M45D1Q-13 offers a variety of advantages for applications which require high-current rectification. Its low voltage drop enables low power dissipation for the rectification process, resulting in improved energy efficiency. It also offers a wide temperature range of operation, allowing for efficient and reliable operation under various environment conditions. Additionally, the module can function as a voltage doubler, allowing for better regulation of output voltage when multiple outputs are required.

Conclusion

The SBR20M45D1Q-13 is a single-phase bridge rectifier module with double diodes connected in an anti-parallel configuration. This module is primarily used in power supplies and AC power conversion applications, such as rectification, inversion, and DC-DC conversion. The module offers a variety of advantages, including low voltage drop and wide operating temperature range.
