VBO125-16NO7

Bridge Rectifier Overview

The IXYS VBO125-16NO7 is a single-phase bridge rectifier module from the VBO series, designed for high-power industrial applications. It features a peak repetitive reverse voltage (Vrrm) of 1600 V and an average forward current (If) of 125 A. The device utilizes a PWS-E screw-mount package with four terminals, measuring 94 mm in length, 54 mm in width, and 30 mm in height. Key electrical parameters include a maximum forward voltage drop (Vf) of 1.43 V at 300 A and a peak non-repetitive forward surge current (Ifsm) of 1.8 kA. The module operates within a junction temperature range of -40°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the specific suffix NO7 against official IXYS documentation to confirm pinout configuration and terminal type. Ensure the ordering part number matches the required voltage and current ratings for your circuit design. Cross-reference datasheet revisions to confirm mechanical dimensions and thermal characteristics before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component when a 1600 V rating and 125 A continuous current are required in a compact screw-mount form factor. Compare the 1.43 V forward voltage drop against system efficiency targets. Verify that the PWS-E package dimensions fit the available heatsink or chassis space. Confirm compatibility with the intended operating temperature range up to 150°C.

Bridge Rectifier Part Context

This module belongs to the IXYS VBO series of single-phase rectifier bridges. The series is characterized by robust construction using DCB technology and planar passivation. These modules are engineered for demanding environments requiring high current handling and reliable blocking voltage performance in industrial power conversion systems.

Bridge Rectifier Replacement Considerations

Direct substitutes may include other IXYS VBO series parts with matching 1600 V and 125 A ratings, such as VBO125-12NO7, provided the voltage rating meets or exceeds requirements. Verify mechanical footprint compatibility with the PWS-E package before substitution.
