HFA80NC40CSM

Diode Arrays Overview

The HFA80NC40CSM is a HEXFRED ultrafast soft recovery diode module in an SMD-61-8 package. It features a 400V cathode-to-anode voltage rating and supports up to 85A continuous forward current at 25°C case temperature. Key electrical parameters include a typical reverse recovery time of 30ns, peak recovery current of 6A, and reverse recovery charge of 200nC. The junction-to-case thermal resistance is 0.85 K/W per leg.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'SM' against the manufacturer datasheet to confirm surface mount compatibility and pinout configuration. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values under both single and dual-leg conducting conditions.

Diode Arrays Selection Notes

Select this component when low reverse recovery charge and fast switching speeds are critical for efficiency. Evaluate the thermal impedance curves to determine appropriate heat sinking requirements based on the expected duty cycle and ambient operating temperature range.

Diode Arrays Part Context

This device belongs to the HEXFRED series from Vishay General Semiconductor - Diodes Division. It utilizes silicon technology designed specifically for ultrafast recovery performance. The module integrates two diodes in a common cathode configuration within a standardized surface mount footprint.

Diode Arrays Replacement Considerations

Check for direct substitutes within the HEXFRED family that match the 400V rating and D61-8-SM package dimensions. Verify that any replacement maintains equivalent reverse recovery time and forward voltage drop specifications to ensure circuit compatibility.
