SD103CWS-HG3-08

SD103CWS-HG3-08 is a diode rectifier single component, mainly element for AC-DC conversion, designed for the automotive industry. It is configured for use as a negative middle point diode in isolated DC-DC applications. This component is manufactured by Diodes Incorporated, utilizing advanced silicon-based technology for improved efficiency, low power losses, and supreme reliability.

General Characteristics

SD103CWS-HG3-08 is a single rectifier component, rated to 10 A with a maximum repetitive peak reverse voltage (VRRM) of 500 V. Its on-state voltage drop is 0.85 V, a surge (non-repetitive) forward current rating of 150 A, and an average forward current rating of 10 A. It has a junction temperature rating of 175°C, and its isolation rating is 4000 Vrms. Because of its soft recovery characteristic, the negative dV/dt at I/O = 10 A/175°C is minimized, resulting in low EMI noise. The single rectifier has an operating temperature range of -55°C to +175°C.

Application Field and Working Principle

The SD103CWS-HG3-08 is primarily used in various isolated DC-DC converters and bridges, particularly in automotive applications. In such a configuration, it is used as a negative middle point diode to provide an unbiased minimum voltage level and absorb the output current. The device has a high surge current capability and fast switching speed, allowing it to handle a high load during operation. During commutation, its soft recovery characteristic prevents high dV/dt from generating EMI noise.

The general operating principle of a single rectifier starts with an AC to DC power conversion, which is facilitated by positive and negative diodes. The positive diode is responsible for conducting the positive half-cycle of the sine wave, while the negative diode conducts the negative half-cycle. This allows the DC voltage to reach the load, thus facilitating the AC to DC power conversion.

SD103CWS-HG3-08 incorporates advanced silicon-based technology for improved performance and reliability. Utilizing the device in the automotive industry, it is proven to reduce power losses and enable fast switching speeds, hence enabling higher operating efficiency.

Conclusion

SD103CWS-HG3-08 is a single-diode rectifier component, specifically designed for use in the automotive industry and other isolated DC-DC applications. With its high surge capability and low power losses, the device enables higher power conversion efficiency and reliability. This diode rectifier single component effectively absorbs the output current and provides an unbiased minimum voltage level, without producing EMI noise due to its soft recovery characteristic.
