Overview
The IXYS VUO82-18NO7 is a three-phase rectifier bridge module from the VUO 82 series. It features a maximum repetitive reverse voltage (VRRM) of 1800 V and an average forward current (IdAV) of 88 A at a case temperature of 110°C. The non-repetitive peak surge current (IFSM) reaches 820 A for an 8.3 ms sine wave pulse. The module exhibits a typical forward voltage drop (VF) of 1.6 V at 150 A and a maximum reverse leakage current of 0.3 mA at 25°C. Operating junction temperatures range from -40°C to +150°C, with thermal resistance values specified per diode and per module.
Feature Summary
- Planar passivated chips designed for high blocking voltages up to 1800 V
- Low forward voltage drop characteristics for improved efficiency
- High isolation voltage capability of 3000 Vrms
Applications
- Input rectifiers for PWM inverters
- Supplies for DC power equipment
- Battery DC power supplies
- Field supply for DC motors
Procurement Notes
Verify the specific part number against official manufacturer documentation before procurement. Confirm that the suffix NO7 corresponds to the exact pinout and mounting configuration required for your application. Ensure compliance with RoHS directives if applicable to your project specifications.
Selection Notes
Select this component based on the 1800 V reverse voltage rating and 88 A continuous current capacity. Evaluate the thermal resistance parameters to ensure adequate heat sinking for the intended operating environment. Consider the physical dimensions and mounting torque requirements for mechanical integration.
Part Context
This device belongs to the VUO 82 series of three-phase rectifier bridges manufactured by IXYS. The series offers various voltage ratings from 800 V to 1800 V, sharing common package styles and mounting interfaces. The VUO82-18NO7 represents the highest voltage variant in this specific current-rated lineup.
Replacement Considerations
Cross-reference with other VUO 82 series variants such as VUO82-16NO7 or VUO82-14NO7 if lower voltage ratings are acceptable. Verify compatibility with alternative manufacturers' three-phase bridge modules offering similar current and voltage specifications.
