VHF125-16IO7

SCRs - Modules Overview

The IXYS VHF125-16IO7 is a half-controlled single-phase rectifier bridge (B2HKF) with an integrated freewheeling diode. It features screw terminals and planar passivated chips within an isolated package rated for 3000 V~ isolation voltage. The module supports a maximum repetitive off-state voltage of 1600 V and an average forward current of 123 A at 85°C case temperature. Key electrical parameters include a surge current capacity of up to 1600 A, a gate trigger voltage under 1.5 V, and a junction temperature range from -40°C to +125°C.

SCRs - Modules Feature Summary

• Half-controlled single-phase rectifier bridge configuration with built-in freewheeling diode
• Isolated package design with screw terminal mounting for secure installation
• Planar passivated chip technology for enhanced reliability

SCRs - Modules Applications

• DC motor control systems

SCRs - Modules Procurement Notes

Verify the specific voltage rating suffix against the datasheet table, as the VHF125 series includes variants for 1200V, 1400V, and 1600V. Confirm that the component is sourced from authorized distributors or the manufacturer, as the provided documentation indicates this model may be phase-out status. Ensure compatibility with existing thermal management solutions given the specified thermal resistance values.

SCRs - Modules Selection Notes

Select this module when a compact, high-current single-phase rectification solution with freewheeling capability is required. The choice depends on matching the 1600V blocking voltage to the circuit's peak reverse voltage requirements. Evaluate the thermal performance using the provided RthJC values and ensure the cooling system can maintain the case temperature below 85°C to sustain the 123 A average current rating.

SCRs - Modules Part Context

This component belongs to the IXYS VHF series of silicon controlled rectifier modules. These modules are designed for industrial power applications requiring robust thyristor-based rectification. The VHF125 variant specifically targets higher current densities compared to the VHF85 counterpart, offering improved space and weight savings through its integrated bridge and diode architecture.

SCRs - Modules Replacement Considerations

Direct replacements should be sought from the same VHF125 series with identical voltage ratings (e.g., VHF125-12IO7 or VHF125-14IO7 if lower voltage is acceptable). Verify pinout compatibility and mounting dimensions before substitution.
