MR750

MR750 Description

The MR750 from onsemi is a general-purpose diode designed for high-current rectification in demanding electronic circuits. Housed in a Microde Button package with an axial configuration, this through-hole mounted diode offers a 50V maximum reverse voltage (Vr) and a 6A average rectified current (Io), making it suitable for medium-power applications. Its standard recovery time (>500ns) ensures reliable switching performance, while the low forward voltage drop (900mV @ 6A) minimizes power dissipation. The MR750 is classified under EAR99 ECCN and is REACH unaffected, ensuring compliance with environmental regulations. Though marked as obsolete, it remains a robust choice for legacy designs requiring dependable rectification.

MR750 Features

• High Current Handling: Supports up to 6A average rectified current (Io) for power applications.
• Low Forward Voltage: 900mV @ 6A reduces energy loss and heat generation.
• Standard Recovery Time: >500ns ensures efficient switching in rectifier circuits.
• Robust Construction: Microde Button (axial) package provides mechanical durability.
• Compliance: EAR99, REACH Unaffected, and HTSUS 8541.10.0080 certified.
• Low Leakage Current: 25µA @ 50V enhances efficiency in blocking reverse current.

MR750 Applications

The MR750 is ideal for:

• Power Supplies: Used in AC-DC converters and bridge rectifiers due to its high current capability.
• Motor Drives: Provides reliable rectification in H-bridge circuits for brushed DC motors.
• Industrial Equipment: Suitable for welding machines, UPS systems, and other high-power electronics.
• Legacy Systems: A dependable choice for maintenance and repairs of older electronic designs.

Conclusion of MR750

The MR750 is a versatile, high-current diode with a balance of efficiency and durability, making it well-suited for medium-power rectification tasks. While obsolete, its low Vf, robust packaging, and compliance with industry standards ensure continued relevance in industrial, power, and legacy applications. Engineers seeking a cost-effective, reliable rectifier for demanding environments will find the MR750 a practical solution.
