M3P75A-140

Overview

The M3P75A-140 is a three-phase standard silicon rectifier bridge manufactured by GeneSiC Semiconductor. It features a 5-SMD module package designed for base mounting. The device supports a repetitive peak reverse voltage (VRRM) of 1400 V and handles a continuous forward current (IF) of 75 A. Key electrical characteristics include a maximum non-repetitive peak reverse voltage of 1500 V, an I2t rating of 1000 A²s, and a surge forward current capability of 1700 A. The junction-to-case thermal resistance is 0.25 °C/W. Operating temperature ranges from -40°C to 150°C, with storage limits between -40°C and 125°C.

Feature Summary

• Terminals and the mounting plate are electrically isolated within the three-phase package structure.
• Diode chips are coated with zinc oxide glass to provide high resistance against temperature and humidity variations.
• Six diode chips are internally connected in a three-phase bridge circuit configuration.
• Modules can be installed on the same cooling fin as other units to save installation space.

Applications

• Inverters for AC motors
• Power supply units for DC motors
• DC power supply units for battery chargers

Procurement Notes

Verify the specific part number suffix against official GeneSiC Semiconductor documentation to confirm exact voltage ratings and packaging specifications. Ensure that procurement channels source directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference datasheet revisions to align with current manufacturing standards before finalizing orders.

Selection Notes

Select this component based on its 1400 V reverse voltage rating and 75 A continuous current capacity. Evaluate the 0.25 °C/W thermal resistance for heat sink design requirements. Confirm compatibility with the 5-SMD base-mount footprint and verify that the operating temperature range meets the application's environmental constraints.

Part Context

This component belongs to the M3P75A series of three-phase rectifiers, which covers voltage ratings from 800 V to 1600 V. All variants in this series share the same 75 A current rating and 5-SMD module form factor. The M3P75A-140 specifically addresses applications requiring higher voltage blocking capabilities compared to lower-rated siblings like the M3P75A-80.

Replacement Considerations

Direct replacements must match the 75 A current rating, 1400 V minimum reverse voltage, and 5-SMD base-mount package. Verify thermal resistance and pinout compatibility. Consult official substitution lists from GeneSiC Semiconductor for confirmed equivalent part numbers within the M3P75A series.
