VBO25-16AO2

Bridge Rectifier Overview

The IXYS VBO25-16AO2 is a single-phase rectifier bridge module from the VBO40 series, rated for a repetitive peak reverse voltage (VRRM) of 1600 V. It features an average forward current (IdAV) of 31 A at a case temperature of 85°C and supports a maximum junction temperature of 150°C. The device utilizes planar passivated silicon chips within a screw-mount package designed for panel installation. Key electrical parameters include a peak forward voltage of 1.36 V at 55 A and a non-repetitive surge current capacity of 370 A for 10 ms at 50 Hz. The module provides an isolation voltage of 3600 Vrms and incorporates avalanche-rated characteristics.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm the voltage rating and avalanche capability. Ensure mounting hardware matches the specified M5 or 10-32 UNF torque requirements. Confirm that the application environment stays within the -40°C to +150°C operating range. Check for any regional compliance certifications required for the end product.

Bridge Rectifier Selection Notes

Select this component when a single-phase rectification solution with high voltage blocking capability is required. The 1600 V rating suits industrial applications with significant line transients. Consider the thermal resistance values for heatsink design. Verify that the physical dimensions of the SOT-227 compatible package fit the available board space.

Bridge Rectifier Part Context

This part belongs to the IXYS VBO series of single-phase rectifier bridges. The series offers various voltage ratings from 800 V to 1600 V. The 'AO' suffix typically denotes the avalanche-rated variant within the standard VBO lineup. These modules are designed for general purpose power conversion in industrial settings.

Bridge Rectifier Replacement Considerations

Cross-reference with other IXYS VBO25 variants such as VBO25-16NO2 for non-avalanche options. Compare thermal impedance curves with competitors like Semikron or Mitsubishi for equivalent performance in similar packages.
