Diode Arrays datasheet and documents for HFA240NJ40D

HFA240NJ40D

Diode Arrays Overview

The HFA240NJ40D is a HEXFRED ultrafast, soft recovery diode module in a TO-244AB package. It features two series-connected legs rated for 400V reverse voltage and 240A average forward current per leg. Key electrical parameters include a typical reverse recovery time of 50ns, peak recovery current of 7.5A, and reverse recovery charge of 290nC at 25°C. The device operates within a junction temperature range of -55°C to +150°C.

Diode Arrays Feature Summary

Optimized for high-frequency power conditioning systems to reduce switching losses and EMI/RFI.
Soft recovery characteristics eliminate the need for snubbers in most applications.
Extensive characterization of recovery parameters simplifies loss calculations across varying currents, temperatures, and di/dt values.

Diode Arrays Applications

Power converters
Motor drives
High-frequency full hybrid and mild hybrid vehicle systems

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact configuration and compliance status. Ensure that the thermal interface material application matches the datasheet requirements for mounting torque and surface flatness to maintain specified thermal resistance values during installation.

Diode Arrays Selection Notes

Select this component when designing circuits requiring low reverse recovery charge and fast switching speeds to minimize energy loss. Consider the thermal impedance characteristics and the requirement for smooth, flat mounting surfaces with thermal grease to ensure reliable operation under high continuous or pulsed current loads.

Diode Arrays Part Context

This part belongs to Vishay's HEXFRED family of ultrafast rectifiers designed for efficiency in high-frequency applications. It utilizes silicon technology in a modified TO-244AB flange mount package, providing robust performance for general-purpose rectification where switching speed and soft recovery are critical design factors.
