VUO82-14NO7

Overview

The IXYS VUO82-14NO7 is a three-phase rectifier bridge module featuring screw terminals and planar passivated chips. It offers a peak repetitive reverse voltage (VRRM) of 1400 V and a maximum average forward current (IdAV) of 88 A at a case temperature of 110°C. The device supports a non-repetitive peak surge current (IFSM) of up to 820 A for an 8.3 ms sine wave at 60 Hz. Key electrical characteristics include a forward voltage drop (VF) of 1.6 V at 150 A, a reverse leakage current (IR) of 0.3 mA at 25°C, and a thermal resistance from junction to case (RthJC) of 1.1 K/W per diode. The module operates within a junction temperature range of -40°C to +150°C.

Feature Summary

• Features screw terminals for easy mounting with two screws
• Provides isolation voltage of 3000 V~
• Utilizes planar passivated chips for improved temperature and power cycling performance

Applications

• Supplies for DC power equipment
• Input rectifiers for PWM inverters

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm voltage ratings and package compatibility. Confirm thermal management requirements align with the specified RthJC values. Ensure mounting torque specifications are strictly followed to maintain mechanical integrity and electrical isolation standards during installation.

Selection Notes

Select this component when a robust three-phase rectification solution with high surge current capability is required. Consider the 1400 V rating for medium-voltage industrial applications. Evaluate the thermal resistance parameters against the system's cooling strategy to ensure the junction temperature remains within the specified operational limits under continuous load conditions.

Part Context

This part belongs to the VUO82 series of three-phase rectifier bridges manufactured by IXYS. The series is characterized by its use of planar passivated chips and screw-terminal packaging, designed for space and weight savings in industrial power electronics. It serves as a standard solution for converting AC input to DC output in various heavy-duty power conversion systems.

Replacement Considerations

Cross-reference with other VUO82 variants such as VUO82-16NO7 or VUO82-12NO7 if different voltage ratings are needed. Verify pinout and dimensional compatibility before substituting with modules from other manufacturers to ensure proper mechanical fit and electrical performance equivalence.
