DF150AB80

Bridge Rectifier Overview

The SanRex DF150AB80 is a three-phase diode bridge rectifier module designed for high-power industrial applications. It features an isolated package with a height of 22 mm and utilizes unique glass passivation for high reliability. The device supports a repetitive peak reverse voltage of 800 V and delivers a DC output current of 150 A at a case temperature of 100 °C. Key electrical characteristics include a maximum forward voltage drop of 1.20 V at 150 A, a surge forward current capacity of 1100 A (50 Hz), and a junction-to-case thermal impedance of 0.14 °C/W. The module operates within a junction temperature range of -40 °C to +150 °C and provides an isolation breakdown voltage of 2500 Vrms.

Bridge Rectifier Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm technical specifications and compliance status. Ensure that the procurement channel is authorized by SanRex Corporation to guarantee product authenticity and access to valid datasheets. Cross-reference the component details with the latest available public data before finalizing acquisition decisions.

Bridge Rectifier Selection Notes

Select this component based on its 800 V reverse voltage rating and 150 A continuous current capability. Consider the 0.14 °C/W thermal impedance for heat sink design requirements. Verify that the application environment falls within the specified operating junction temperature range of -40 °C to +150 °C and requires an isolated package structure.

Bridge Rectifier Part Context

This component belongs to the SanRex DF series of three-phase diode modules. It shares the same physical dimensions and general structural design with the DF150AB160 variant, which offers a higher 1600 V reverse voltage rating while maintaining identical current handling and thermal characteristics.

Bridge Rectifier Replacement Considerations

The DF150AB160 serves as a direct functional substitute within the same series, offering identical mechanical and thermal properties with a higher voltage rating of 1600 V.
