MLO175-16IO7

Overview

The IXYS MLO175-16IO7 is a thyristor controller module designed for AC circuit applications. It features an RMS current rating of 175 A and supports voltage ratings from 800 V to 1600 V, with the -16 variant rated at 1600 V. The device utilizes planar glass passivated chips and offers an isolation voltage of 3000 V~. Key electrical parameters include a maximum average on-state current (ITAVM) of 80 A, a non-repetitive peak surge current (ITSM) of up to 1600 A, and a critical rate of rise of on-state current ((di/dt)cr) of 150 A/µs. The module operates within a junction temperature range of -40°C to +150°C.

Procurement Notes

Verify the specific voltage suffix matches the application requirement, as the series covers 800V, 1200V, and 1600V options. Confirm mounting torque specifications (1.5...2.0 Nm) during installation. Check datasheet for thermal resistance values relevant to the cooling method. Ensure gate trigger characteristics align with the driving circuit design. Validate compliance with IEC 60747 standards if required by the system specification.

Selection Notes

Select this module for high-power AC control applications requiring robust surge handling and high isolation. Consider the 175 A RMS rating and 1600 V blocking capability for mains frequency operations. Evaluate thermal management needs based on the specified junction temperature limits and thermal resistance data. Ensure the gate drive circuit can provide the necessary trigger current and voltage levels under varying temperature conditions.

Part Context

This component belongs to the MMO/MLO 175 series of AC controller modules manufactured by IXYS. The series is designed for mains frequency applications, offering high power density and space savings.
