VVZF70-16IO7 Equivalent & Substitute Parts

Part Overview

The VVZF70-16IO7 is a 3-phase SCR bridge rectifier module rated for 1.6 kV off-state voltage with a maximum on-state current of 70 A (average). Manufactured by IXYS, this thyristor module integrates three SCRs and three diodes in a chassis-mount configuration using the FO-T-A package. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VVZF70-16IO7 is determined by strict equivalence in the following electrical and mechanical parameters:

• Voltage Rating: Off-state voltage must equal 1.6 kV
• Bridge Configuration: 3-phase SCR/diode bridge structure required
• Gate Trigger Characteristics: Vgt (Max) 1.5 V and Igt (Max) 100 mA
• Hold Current: Ih (Max) 200 mA
• Operating Temperature: -40°C to 125°C (TJ)
• Mounting: Chassis mount configuration
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part VVZ175-16IO7 meets all these core electrical parameters while maintaining the same voltage class, gate trigger specifications, and thermal operating range. The primary difference is an increased on-state current rating (167 A average vs. 70 A), which represents a higher current capacity within the same voltage and control characteristic class.

Parameter Comparison

Engineering Selection Recommendations

The VVZ175-16IO7 is the direct substitute for the obsolete VVZF70-16IO7. Both components maintain identical voltage ratings, gate trigger specifications, and thermal operating ranges. The VVZ175-16IO7 is currently in active production status with higher inventory availability, ensuring supply chain continuity.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The VVZ175-16IO7 provides increased on-state current capacity (167 A vs. 70 A), which is compatible with applications originally designed for the VVZF70-16IO7 and offers enhanced performance margin in higher-current scenarios.

Frequently Asked Questions (FAQ)

Q: Can the VVZ175-16IO7 directly replace the VVZF70-16IO7?

A: Yes. Both components share identical voltage ratings (1.6 kV), gate trigger characteristics (Vgt 1.5 V max, Igt 100 mA max), hold current (200 mA max), and operating temperature range (-40°C to 125°C). The VVZ175-16IO7 has higher on-state current capacity, which is a compatible upgrade.

Q: What is the primary difference between these two parts?

A: The on-state current rating differs: VVZF70-16IO7 is rated for 70 A average, while VVZ175-16IO7 is rated for 167 A average. All other electrical and mechanical parameters are equivalent.

Q: Are there package compatibility considerations?

A: The VVZF70-16IO7 uses the FO-T-A package, while the VVZ175-16IO7 uses the PWS-E2 package. Both are chassis-mount configurations. Physical dimensions and mounting hole patterns may differ; mechanical fit must be verified for the specific application.

Q: Why is the VVZF70-16IO7 obsolete?

A: The VVZF70-16IO7 has been discontinued by IXYS. The VVZ175-16IO7 is the active production equivalent that maintains electrical compatibility while offering improved current capacity.

Q: Are both parts compliant with current regulations?

A: Yes. Both the VVZF70-16IO7 and VVZ175-16IO7 are ROHS3 compliant and REACH unaffected.
