M3P75A-120

Overview

The M3P75A-120 is a three-phase silicon standard recovery diode bridge rectifier manufactured by GeneSiC Semiconductor. It operates within a repetitive peak reverse voltage range of 800 V to 1600 V, with the specific M3P75A-120 variant rated at 1200 V. The module supports a continuous forward current of 75 A and features electrically isolated terminals and mounting plates. Packaged in a 5-SMD base-mount configuration, it utilizes six internal diode chips connected in a bridge circuit. Key electrical characteristics include a maximum forward voltage of 1.15 V at 75 A and a thermal resistance from junction to case of 0.25 °C/W.

Feature Summary

• Electrically isolated terminals and mounting plate for safe installation
• Glass zinc oxide coating on diode chips for environmental resistance
• Integrated six-diode three-phase bridge rectifying circuit
• Compatible with shared cooling fins to save installation space

Applications

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

Procurement Notes

Verify the exact voltage rating suffix against the datasheet table, as the series spans 800 V to 1600 V. Confirm the manufacturer designation, noting that GeneSiC Semiconductor products are often associated with Navitas Semiconductor. Ensure the package type matches the required board layout for the 5-SMD base-mount form factor before ordering.

Selection Notes

Select this component when a robust three-phase rectification solution is required for high-current applications up to 75 A. The low thermal resistance facilitates efficient heat dissipation when mounted on shared cooling infrastructure. Consider the operating temperature range and the specific voltage derating requirements for the target system environment.

Part Context

This part belongs to the M3P75A series of three-phase silicon standard recovery diodes. The series includes variants ranging from 800 V to 1600 V, all sharing the same 75 A current rating and physical package dimensions. This allows for design flexibility regarding voltage ratings without changing the mechanical footprint or thermal management strategy.

Replacement Considerations

Direct replacements must match the 75 A current rating, 1200 V minimum reverse voltage, and 5-SMD base-mount package. Verify that substitute components offer comparable thermal resistance and forward voltage characteristics to maintain system efficiency.
