VHFD16-14IO1

SCRs - Modules Overview

The VHFD16-14IO1 is a half-controlled single-phase rectifier bridge manufactured by IXYS. It utilizes silicon planar passivated chips mounted on a DCB ceramic base plate within a V1-A-Pack screw-mount housing. The module supports a repetitive peak reverse voltage of 1400V and an average forward current of 21A. Key electrical characteristics include a maximum isolation voltage of 3600Vrms between terminals and the base plate, ensuring safe operation in high-voltage industrial environments.

SCRs - Modules Feature Summary

• Constructs a half-controlled single-phase rectifier bridge using planar passivated silicon chips for reliable switching performance.
• Integrates a Direct Bonded Copper (DCB) ceramic base plate to provide robust thermal management and electrical isolation.
• Features a screw-mount design compatible with standard PC board leads, facilitating easy mechanical installation and space-efficient mounting.

SCRs - Modules Applications

• Power supply units for DC equipment
• DC motor control systems

SCRs - Modules Procurement Notes

Verify component authenticity through authorized IXYS distributors or certified partners. Confirm that the specific suffix IO1 matches the required pinout and insulation class for your application. Check for RoHS compliance status and ensure storage conditions adhere to semiconductor handling standards to prevent moisture sensitivity damage prior to assembly.

SCRs - Modules Selection Notes

Select this module when a compact half-controlled bridge is required for 1400V applications. The 21A rating suits moderate power levels where thermal dissipation via a heatsink is feasible. Consider the V1-A-Pack package dimensions for PCB layout constraints. Ensure the gate drive circuitry aligns with the SCR characteristics of the controlled legs within the bridge configuration.

SCRs - Modules Part Context

This component belongs to the VHFD16 series of half-controlled rectifier bridges from IXYS. The series offers various voltage ratings, including 800V, 1200V, 1400V, and 1600V options. These modules are designed for industrial power conversion, combining high blocking voltages with efficient thermal transfer capabilities in a standardized screw-mount form factor.

SCRs - Modules Replacement Considerations

Cross-reference with other IXYS VHFD16 variants such as VHFD16-12IO1 or VHFD16-16IO1 if voltage ratings differ. Verify that substitute parts maintain the same V1-A-Pack footprint and pin configuration to ensure mechanical compatibility without redesigning the mounting structure.
