VS-HFA04TB60PBF

Single Diodes Overview

The VS-HFA04TB60PBF is a HEXFRED ultrafast soft recovery diode manufactured by Vishay Semiconductors. It features a single die configuration in a TO-220AC package with a base cathode design. The device provides a maximum repetitive reverse voltage of 600 V and supports a continuous forward current of 4 A at 100 °C case temperature. Typical electrical characteristics include a forward voltage of 1.5 V at 4 A, a peak reverse leakage current of 3.0 μA at rated voltage, and a typical reverse recovery time of 17 ns under specified test conditions.

Single Diodes Feature Summary

• Ultrafast and ultrasoft recovery characteristics designed to minimize switching noise
• Extremely low peak reverse recovery current (IRRM) and stored charge (Qrr)
• No tendency to snap-off during the tb portion of recovery
• Qualified according to JEDEC JESD47 standards for industrial level reliability

Single Diodes Applications

• Companion diodes for IGBTs and MOSFETs
• High frequency power supplies and power conversion systems such as inverters
• Motor drives requiring high speed and high efficiency

Single Diodes Procurement Notes

Verify that the ordering suffix matches the required environmental compliance. The PbF suffix indicates lead-free and RoHS-compliant construction. The -N3 suffix denotes halogen-free, RoHS-compliant, and totally lead-free materials. Confirm the specific variant aligns with project material restrictions before procurement.

Single Diodes Selection Notes

Select this component when low electromagnetic interference and reduced snubbing requirements are critical. The ultrafast recovery profile minimizes power loss in both the diode and the associated switching transistor. Ensure thermal management accommodates the junction-to-case thermal resistance of 5.0 K/W for optimal performance at elevated temperatures.
