VBO22-12NO8

Bridge Rectifier Overview

The IXYS VBO22-12NO8 is a single-phase rectifier bridge module featuring planar passivated chips and fast-on terminals. It provides a peak repetitive reverse voltage (VRRM) of 1200 V and supports an average forward current (IdAV) of 21 A at a case temperature of 63°C, or 17 A at 85°C. The device withstands a non-repetitive surge current (IFSM) of 440 A for 8.3 ms. Key electrical parameters include a maximum reverse leakage current of 5.0 mA at TVJM, a forward voltage drop of 2.2 V at 150 A, and thermal resistances of 9.40 K/W per diode and 2.35 K/W per module.

Bridge Rectifier Feature Summary

• Utilizes planar passivated chip technology for improved reliability
• Features ¼" fast-on terminals for simplified mounting with a single screw
• Provides 3000 V~ isolation voltage between terminals and base
• Offers low forward voltage drop to enhance efficiency

Bridge Rectifier Applications

• Supplies for DC power equipment
• Input rectifiers for PWM inverters
• Battery DC power supplies
• Field supply for DC motors

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix NO8 against official IXYS documentation to confirm terminal type and package configuration. Ensure that the required blocking voltage matches the 1200 V rating, as other variants in the VBO22 series offer different voltage levels. Confirm compliance with UL registration E 72873 if required for the target application.

Bridge Rectifier Selection Notes

Select this component when a single-phase bridge with 1200 V blocking capability and approximately 21 A continuous current is needed. Consider the thermal resistance values for heatsinking requirements. Verify that the operating case temperature remains within limits to sustain the rated current, noting the derating curve from 21 A at 63°C to 17 A at 85°C.

Bridge Rectifier Part Context

This part belongs to the VBO22 series of single-phase rectifier bridges manufactured by IXYS. The series includes variants with blocking voltages ranging from 800 V to 1800 V. All models in this family share the same physical package dimensions and terminal configuration, differing primarily in their voltage ratings and associated surge current capabilities.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 1200 V rating, 21 A current capacity, and SOT-227-like footprint with fast-on terminals. Check datasheets for equivalent thermal resistance and forward voltage characteristics to ensure circuit compatibility without modification.
