VBO22-08NO8

Bridge Rectifier Overview

The IXYS VBO22-08NO8 is a single-phase rectifier bridge module featuring planar passivated chips and ¼" fast-on terminals. It provides a peak repetitive reverse voltage (VRRM) of 800 V and supports an average forward current (IdAV) of 17 A at a case temperature of 85°C, or 21 A at 63°C. The device withstands surge currents up to 380 A for 10 ms at 50 Hz. Key electrical parameters include a maximum reverse leakage current of 0.3 mA at 25°C and a forward voltage drop of 2.2 V at 150 A. Thermal resistance from junction to case is 8.20 K/W per diode. The unit operates within a temperature range of -40°C to +150°C and offers an isolation voltage of 3000 V~.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix NO8 against official IXYS documentation to confirm terminal type and package configuration. Ensure thermal management solutions align with the specified junction-to-case thermal resistance values under expected operating conditions. Cross-reference datasheet revision dates to confirm parameter stability before finalizing component selection.

Bridge Rectifier Selection Notes

Select this component when a single-phase bridge with 800 V blocking capability and approximately 20 A continuous current rating is required. Consider the ¼" fast-on terminal style for assembly compatibility. Evaluate thermal dissipation requirements based on the 8.20 K/W junction-to-case resistance and ensure the application environment stays within the -40°C to +150°C operating range.

Bridge Rectifier Part Context

This part belongs to the VBO 22 series of single-phase rectifier bridges from IXYS. The series includes variants with different voltage ratings, such as 1200 V, 1400 V, 1600 V, and 1800 V, sharing similar physical dimensions and terminal configurations. The VBO22-08NO8 specifically addresses applications requiring 800 V reverse blocking voltage.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same family include VBO22-12NO8 (1200 V), VBO22-14NO8 (1400 V), VBO22-16NO8 (1600 V), and VBO22-18NO8 (1800 V). Verify that the higher voltage ratings do not impact cost or availability constraints if substituting upwards.
