VVZ175-12IO7

SCRs - Modules Overview

The VVZ175-12IO7 is a silicon SCR module manufactured by IXYS, designed for high-power applications. It features a rated repetitive off-state voltage (VDRM) of 1.2 kV and an on-state RMS current (It RMS) of 89 A at Tc = 85°C. The device supports a non-repetitive on-state current of 1.6 kA and maintains an on-state voltage of 1.57 V. Key electrical parameters include a maximum holding current of 200 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 100 mA. The module operates within a junction temperature range of -40°C to +125°C and utilizes a PWS-E-2 screw-mount package.

SCRs - Modules Feature Summary

• Integrated three-phase AC controller configuration utilizing six SCRs per module.
• Planar passivated chip technology ensuring robust performance under high power density conditions.
• Metal base plate construction facilitating efficient thermal management and mechanical mounting via screws.

SCRs - Modules Applications

• Switching and control of three-phase AC circuits
• Soft-start controllers for AC motors
• Solid-state switches in industrial systems

SCRs - Modules Procurement Notes

Verify the specific suffix IO7 against official IXYS documentation to confirm pinout compatibility and isolation ratings. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration before integration. Ensure the procurement channel provides valid traceability for semiconductor components intended for critical infrastructure or industrial machinery applications.

SCRs - Modules Selection Notes

Select this component when a compact solution for three-phase AC control is required with a 1.2 kV blocking capability. The 89 A RMS rating suits moderate-to-high power industrial loads. Evaluate thermal resistance requirements relative to the PWS-E-2 package size. Compare against the VVZ175-16IO7 variant if higher voltage insulation is necessary for the specific circuit topology.

SCRs - Modules Part Context

This part belongs to the VVZ175 series of thyristor modules from IXYS, a subsidiary of Littelfuse. The series focuses on high-current silicon-controlled rectifiers packaged for industrial power electronics. These modules are engineered for reliability in demanding environments, serving as core switching elements in converters and motor drives.

SCRs - Modules Replacement Considerations

The VVZ175-16IO7 serves as a direct functional substitute within the same series, offering identical current ratings but with a higher 1.6 kV voltage rating. Verify that the increased voltage rating does not impact gate drive requirements or system insulation design when performing the swap.
