VUO84-16NO7

Overview

The VUO84-16NO7 is a three-phase rectifier bridge from the IXYS VUO84 series, designed for high-power industrial applications. It features a peak repetitive reverse voltage (Vrrm) of 1600 V and an average forward current (If) of 84 A at a case temperature of 110°C. The module utilizes planar passivated chips to ensure low leakage current and improved thermal cycling reliability. Key electrical parameters include a maximum forward voltage drop (Vf) of approximately 1.5 V and a peak non-repetitive surge current (Ifsm) of 900 A. The device operates within a junction temperature range of -40°C to +150°C and is housed in a PWS-E-5 screw-mount package.
