MG1750S-BN4MM

Overview

The Littelfuse MG1750S-BN4MM is a 1700V, 50A IGBT power module utilizing IGBT3 Trench+Field Stop technology for the switch and EMCON 3 technology for the integrated free-wheeling diode. It features low turn-off losses with short tail current and a positive temperature coefficient for VCE(sat). The module supports high-frequency switching with an operating junction temperature range of -40°C to 125°C and a maximum rating of 150°C. Key electrical parameters include a collector-emitter saturation voltage of 2.45V typ at 25°C and 50A, and a gate-emitter threshold voltage of 5.8V typ. It provides 4000V AC insulation test voltage and weighs 160g.

Procurement Notes

Verify the specific assembly site indicated by the suffix against current manufacturing locations. Confirm that the bulk packing mode meets your handling requirements. Ensure the recommended torque values for module-to-sink and electrode connections are strictly followed during installation to maintain thermal performance and mechanical integrity.

Selection Notes

Select this module for applications requiring 1700V blocking capability and up to 50A continuous current at 80°C case temperature. Consider the integrated gate resistor value when designing the driver circuit to achieve desired switching speeds. Evaluate the thermal resistance specifications against your heatsink design to ensure junction temperatures remain within the 150°C absolute maximum limit under expected load conditions.

Part Context

This component belongs to Littelfuse's MG series of power modules, which are designed for industrial power conversion. The series utilizes advanced trench field-stop technologies to optimize efficiency in medium-power applications. These modules integrate both IGBT switches and anti-parallel diodes in a single package to simplify circuit design and reduce parasitic inductance compared to discrete solutions.

Replacement Considerations

Direct replacement requires matching the 1700V/50A rating and similar pinout configuration. Verify thermal resistance and package dimensions to ensure compatibility with existing heatsinks. Check if alternative modules offer comparable switching energy values to maintain system efficiency without redesigning the gate drive circuitry.
