HFA200MD40D

Diode Arrays Overview

The HFA200MD40D is a HEXFRED ultrafast, soft recovery diode module manufactured by Vishay General Semiconductor - Diodes Division. It features an isolated TO-244AB package with two silicon rectifier elements configured as a center-tapped arrangement. The device supports a maximum cathode-to-anode voltage of 400 V and delivers a continuous forward current of 172 A at a case temperature of 25°C. Key electrical characteristics include a typical reverse recovery time of 45 ns, a peak reverse recovery current of 8.1 A, and a junction-to-case thermal resistance of 0.45 °C/W per leg.

Diode Arrays Feature Summary

• Ultrafast soft recovery design optimized to reduce switching losses and electromagnetic interference in high-frequency power conditioning systems.
• Extensive characterization of recovery parameters across varying current, temperature, and di/dt conditions simplifies loss calculations.
• Soft recovery characteristic eliminates the need for snubber circuits in most applications.

Diode Arrays Applications

• Power converters
• Motor drives
• High frequency power conditioning systems

Diode Arrays Procurement Notes

Verify the manufacturer designation matches Vishay General Semiconductor - Diodes Division or its predecessor International Rectifier (Infineon). Confirm the specific suffix 'D' corresponds to the standard TO-244AB isolated package configuration. Ensure the procurement documentation references the correct datasheet revision PD-2.510 rev. A for accurate thermal and electrical specifications.

Diode Arrays Selection Notes

Select this component when designing circuits requiring ultrafast recovery characteristics to minimize reverse recovery charge and associated switching losses. Evaluate the thermal management requirements based on the specified junction-to-case thermal resistance values for single and dual-leg conducting scenarios. Consider the 400 V rating and 172 A current capacity relative to the expected operating load and ambient cooling conditions.

Diode Arrays Part Context

This component belongs to the HEXFRED family of ultrafast recovery diodes designed for high-efficiency power electronics. The module integrates two discrete silicon rectifier elements within a single flange-mount housing. The isolated base configuration allows for direct mounting to heatsinks without electrical isolation components, facilitating compact thermal designs in industrial power applications.
