VHF28-08IO5

SCRs - Modules Overview

The IXYS VHF28-08IO5 is a silicon-controlled rectifier (SCR) module designed for high-power industrial applications. It features an insulated baseplate and screw-mount installation within the ECO-PAC 1 package. The device supports a rated repetitive off-state voltage of 800V and an RMS on-state current of 28A. Key electrical characteristics include a non-repetitive peak on-state current of 210A, a maximum holding current of 50mA, and a gate trigger voltage of 1.5V with a gate trigger current of 25mA. The module operates reliably within a temperature range of -40°C to +125°C.

SCRs - Modules Feature Summary

SCRs - Modules Procurement Notes

Verify the specific suffix IO5 against official datasheets to confirm insulation class and terminal configuration. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Cross-reference the part number with Littelfuse records, as IXYS power semiconductor assets are managed under this entity. Confirm compliance with RoHS directives if required by your assembly specifications.

SCRs - Modules Selection Notes

Select this component when an insulated SCR module is required for moderate current levels around 28A. The 800V rating suits applications with standard AC line voltages or lower DC bus requirements. Consider the ECO-PAC 1 footprint for board space constraints. Verify that the gate drive circuit can supply at least 25mA to ensure reliable triggering under all operating conditions.

SCRs - Modules Part Context

This device belongs to the VHF series of simple mounting thyristors from IXYS. The series is characterized by its ease of installation and robust construction for industrial power electronics. These modules are engineered to handle significant power densities while maintaining electrical isolation between the terminals and the mounting surface.

SCRs - Modules Replacement Considerations

Check for equivalent models in the VHF series with matching voltage and current ratings. Consult official substitution guides from Littelfuse/IXYS for direct pin-compatible alternatives. Verify that any replacement maintains the same package type and thermal resistance characteristics.
