The 26MT120, manufactured by International Rectifier (now Infineon Technologies), is a three-phase bridge rectifier. Bridge rectifiers like the 26MT120 are used to convert AC (Alternating Current) voltage to DC (Direct Current) voltage. These are commonly used in power supplies and various industrial applications where a reliable DC power source is needed from an AC input.

Applications:

• Power Supplies: Converts AC input to DC output in power supplies for various electronic devices.
• Motor Drives: Supplies DC power to motor drive circuits for controlling motors in industrial equipment.
• Battery Chargers: Rectifies AC voltage for charging batteries in various applications.
• Welding Equipment: Converts AC power to DC power for arc welding applications.
• Uninterruptible Power Supplies (UPS): Provides DC power to inverters in UPS systems.

Features:

• Three-Phase Bridge Rectifier: Converts three-phase AC voltage to DC voltage.
• High Voltage Rating: Can handle high input AC voltages.
• High Current Rating: Capable of handling significant DC output current.
• Isolated Base: Provides electrical isolation between the terminals and the mounting base.
• High Surge Current Capability: Can withstand high surge currents during startup or fault conditions.
• Compact Package: Available in a compact package for easy integration into various equipment.

Benefits:

• Efficient AC-DC Conversion: Provides efficient conversion of AC voltage to DC voltage.
• Reliable Performance: Delivers reliable performance in demanding industrial applications.
• Simplified Design: Simplifies the design of power supplies and other equipment requiring DC power.
• Enhanced Safety: Isolated base provides electrical isolation for enhanced safety.
• Rugged Construction: Withstands harsh environmental conditions in industrial settings.

Additional Details:

Typical specifications for the 26MT120 include:

• Maximum Repetitive Peak Reverse Voltage (Vrrm): 1200V (This is likely what the '120' in the part number refers to, i.e., 120 x 10 = 1200V).
• Maximum Average Forward Rectified Current (If(AV)): 26 Amperes
• Maximum Surge Current (Ifsm): Significantly higher than the average forward current, providing robustness against transient events.
• Operating Temperature Range: Typically spans a wide range suitable for industrial environments.

The 26MT120 is typically packaged in a module with screw terminals for easy and secure connections. The isolated base allows it to be mounted directly to a heatsink for efficient thermal management.
