MMO36-16IO1

Overview

The IXYS MMO36-16IO1 is a thyristor controller module designed for AC mains frequency applications. It features a maximum repetitive peak reverse voltage (VRRM) of 1600 V and an RMS on-state current (IRMS) of 39 A at a heatsink temperature of 85°C. The device utilizes direct copper bonded Al2O3 ceramic base plates with planar passivated chips, providing an isolation voltage of 3600 Vrms. Key electrical characteristics include a gate trigger current (IGT) of 65 mA at 25°C and a holding current (IH) of 100 mA. The module supports a maximum junction temperature (TVJM) of 125°C and operates within a storage temperature range of -40°C to +125°C.

Feature Summary

• Dual-gate configuration enabling independent control of two thyristors within a single compact module.
• Direct copper bonded aluminum oxide ceramic base plate for efficient thermal management and mechanical stability.
• Planar passivated chip technology ensuring robust performance and reliability under high power cycling conditions.
• UL registered component offering enhanced safety compliance for industrial and commercial equipment.

Applications

• Switching and control of single-phase and three-phase AC circuits
• Soft-start controllers for AC motors
• Solid-state switches and relays
• Light dimming and temperature control systems

Procurement Notes

Verify the specific suffix 'MMO' indicates the dual-gate variant when sourcing replacements for MLO series components. Confirm that the 1600V rating aligns with system voltage requirements. Ensure mounting torque specifications are strictly followed during installation to maintain thermal interface integrity and prevent mechanical failure. Cross-reference datasheet revision dates to ensure compatibility with existing design parameters.

Selection Notes

Select this module for applications requiring dual-thyristor control in a space-constrained environment. The 39A RMS rating suits moderate power AC control tasks. Consider the 125°C maximum junction temperature limit for thermal design calculations. The screw-mount package facilitates easy integration into standard heat sink assemblies. Evaluate the 3600V isolation voltage for safety-critical applications requiring galvanic separation.

Part Context

The MMO36 series belongs to IXYS's family of AC controller modules, specifically engineered for mains frequency operation. Unlike the single-gate MLO36 variant, the MMO36 incorporates two independent gates for versatile circuit configurations. These modules are part of a broader lineup including higher current ratings, serving as core switching elements in power electronics where reliable AC phase control is essential.

Replacement Considerations

The MLO36-16IO1 serves as a functional substitute if single-gate operation is sufficient. Verify that the replacement module meets the same 1600V blocking voltage and 39A current ratings. Ensure the pinout compatibility matches the PCB layout, particularly noting the additional gate lead on the MMO variant compared to the MLO version.

FAQ

What is the difference between the MLO36 and MMO36 modules?

The primary difference is the gate configuration. The MMO36 features two independent gates (G1 and G2) for controlling two internal thyristors, whereas the MLO36 has only one gate (G1).

What is the maximum isolation voltage of the MMO36-16IO1?

The module provides an isolation voltage of 3600 Vrms, tested for 1 second at 1 mA leakage current.

How does the gate trigger current vary with temperature?

The gate trigger current (IGT) increases as temperature decreases. It is specified as 65 mA at 25°C and rises to 120 mA at -40°C.
