130MT80KB Three Phase Bridge Rectifier - Equivalent & Substitute Parts

Part Overview

The 130MT80KB is a three-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 800 V peak reverse voltage with 130 A average rectified current. This component is designed for chassis mount applications using the MTK package. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance, repair, and redesign applications where this rectifier is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 130MT80KB is determined by strict equivalence across the following critical parameters:

• Diode Type: Three Phase configuration required
• Voltage Rating: 800 V peak reverse voltage (minimum requirement)
• Current Rating: Average rectified current of 127 A or higher (within acceptable tolerance for 130 A specification)
• Technology: Standard rectifier technology
• Operating Temperature: -40°C ~ 150°C range maintained
• Mounting Configuration: Chassis mount capability

The VUO110-08NO7 from IXYS meets these substitution criteria. While the package designation differs (PWS-E versus MTK), both are chassis mount configurations suitable for three-phase bridge rectifier applications at the specified voltage and current levels.

Parameter Comparison

Engineering Selection Recommendations

The VUO110-08NO7 is the qualified substitute for the 130MT80KB based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical 800 V peak reverse voltage ratings and operate within the same temperature range. The VUO110-08NO7 current rating of 127 A is within acceptable tolerance of the 130 A specification, with actual application requirements determining suitability.

Product Status and Availability: The 130MT80KB is obsolete, while the VUO110-08NO7 is active production. This ensures long-term availability and supply chain continuity for new designs and field replacements.

Compliance Advantage: The VUO110-08NO7 is ROHS3 compliant, whereas the 130MT80KB is non-compliant. For applications subject to RoHS regulations, the IXYS component provides regulatory alignment.

Reverse Leakage Characteristic: The VUO110-08NO7 exhibits lower reverse leakage current (100 µA @ 800 V versus 10 mA @ 800 V), which may provide improved performance in certain circuit topologies.

Frequently Asked Questions (FAQ)

Q: Can the VUO110-08NO7 directly replace the 130MT80KB in existing designs?

A: The VUO110-08NO7 meets the critical electrical parameters (800 V, 127 A, three-phase, standard technology, -40°C to 150°C). Physical mounting compatibility must be evaluated, as the package designations differ (PWS-E versus MTK). Both are chassis mount configurations; however, mechanical fit and thermal interface requirements should be confirmed for your specific application.

Q: What is the significance of the current rating difference (130 A versus 127 A)?

A: The 3 A difference represents approximately 2.3% variance. Whether this is acceptable depends on your circuit's actual current demand and thermal design margin. If the application requires the full 130 A capability, the VUO110-08NO7 may not be suitable without circuit redesign.

Q: Why is the reverse leakage current different between these parts?

A: Reverse leakage current is a function of semiconductor manufacturing process and die design. The VUO110-08NO7's lower leakage (100 µA versus 10 mA) reflects IXYS process technology. This difference is generally beneficial for circuit performance but should not be the primary substitution criterion.

Q: Is RoHS compliance a requirement for substitution?

A: RoHS compliance is a regulatory and supply chain consideration, not an electrical substitution criterion. If your application or market requires RoHS compliance, the VUO110-08NO7 provides this advantage. If not required, compliance status does not affect functional equivalence.

Q: Are there other substitute options available?

A: Based on the provided data, the VUO110-08NO7 is the identified substitute. Additional alternatives may exist in the market; however, any substitute must meet the core parameters: three-phase configuration, 800 V rating, minimum 127 A current capability, standard technology, and -40°C to 150°C operating range.
