VUB120-16NO2

Bridge Rectifier Overview

The IXYS VUB120-16NO2 is a three-phase rectifier bridge module integrating IGBTs and fast recovery diodes for braking systems. It features a 1200V collector-emitter voltage (VCES) with a continuous collector current of 100A at 80°C case temperature. The integrated rectifier diode supports a maximum repetitive reverse voltage of 1600V and an average DC output current of 188A. Surge forward current reaches 1100A, while the fast recovery diode handles 200A surge current. The module provides 3600V isolation voltage and includes an optional NTC temperature sensor.

Bridge Rectifier Procurement Notes

Verify the specific ordering code against the required configuration, as the standard version differs from the variant with the integrated NTC sensor. Confirm that the 1600V rating aligns with system requirements, noting that a 1200V variant also exists within this product family. Ensure compatibility with the recommended replacement part number if sourcing alternatives.

Bridge Rectifier Selection Notes

Select this component when a combined rectifier and IGBT solution is required for braking applications. Consider the 1600V rating over the 1200V variant based on peak voltage stress. Evaluate the need for the optional NTC sensor for precise thermal management. Verify that the 188A average current capability meets the load demands under specified case temperature conditions.

Bridge Rectifier Part Context

This component belongs to the VUB120 series, which combines power switching and rectification capabilities. It is designed to simplify assembly by housing two distinct functions in one outline. The module utilizes a screw-mount design for secure attachment to heatsinks, facilitating efficient thermal dissipation in high-power environments.

Bridge Rectifier Replacement Considerations

The datasheet explicitly recommends the VUB120-16NOX(T) as the replacement part. Verify electrical parameters and pinout compatibility before substitution.
