HFA120EA60

Diode Arrays Overview

The HFA120EA60 is a HEXFRED antiparallel diode module in an electrically isolated SOT-227 package. It features a 600V cathode-to-anode voltage rating and supports a continuous forward current of 75A at 25°C case temperature, decreasing to 40A at 100°C. The device exhibits a typical reverse recovery time of 65ns at 25°C and a maximum junction temperature of 125°C. With a thermal resistance from junction to case of 0.70°C/W per leg, it provides robust performance for high-frequency switching applications.

Diode Arrays Procurement Notes

Verify the specific antiparallel configuration (HFA120EA60) against the parallel variant (HFA120FA60) to ensure correct terminal assignments for series rectifier circuits. Confirm that the SOT-227 mounting torque requirements are met during installation. Check datasheet revisions for any updates to absolute maximum ratings or thermal characteristics before finalizing design specifications.

Diode Arrays Selection Notes

Select this component when high voltage isolation and fast recovery are required in a single module. The antiparallel layout simplifies circuit topology for series rectification compared to discrete components. Ensure the cooling solution maintains the case temperature within limits to sustain the rated 75A continuous current. Evaluate the 600V breakdown voltage against peak transient voltages in the target application environment.
