• Chassis mount design for efficient heat dissipation
• Standard recovery time characteristics

Applications

• Industrial motor drives
• Power supply units
• Welding equipment

Procurement Notes

Verify the specific suffix 'KB' against the official Vishay datasheet to confirm exact electrical tolerances and marking codes, as suffixes often denote specific manufacturing lot or testing variations. Confirm that the MTK package dimensions match the mechanical constraints of the target chassis assembly. Ensure the procurement source provides valid traceability documentation for this obsolete or legacy part number.

Selection Notes

Select this component when high current capacity and three-phase input are required. The MTK package necessitates a compatible heatsink interface for proper thermal operation. Consider the 800V reverse voltage rating relative to the system's line voltage peaks. Evaluate the standard recovery speed against potential electromagnetic interference requirements in the specific application circuit.

Part Context

This device belongs to Vishay's MTK series of three-phase bridge rectifiers. These components are engineered for heavy-duty power conversion tasks. The MTK package type indicates a specific chassis-mount form factor distinct from surface-mount or through-hole alternatives, prioritizing high-power handling over compact footprint.

Replacement Considerations

Consult Vishay's official cross-reference guides for direct replacements. Verify that any substitute matches the 130A current rating, 800V voltage rating, and MTK package dimensions to ensure mechanical and electrical compatibility without redesigning the cooling infrastructure.
