NHP620MFDT1G

Overview

The NHP620MFDT1G is a discontinued ultrafast power rectifier from onsemi, housed in a DFN8 (SO-8FL) package. It features two electrically independent diodes within a single dual-flag footprint, allowing flexible configurations such as common cathode, common anode, or series operation. The device supports a peak repetitive reverse voltage of 200 V and delivers a peak repetitive forward current of 6.0 A. Electrical characteristics include a maximum reverse recovery time of 50 ns at 50°C and a junction-to-case thermal resistance of 3.4°C/W.

Feature Summary

• Dual flag SO-8 flat lead package enables versatile board-level layout options including separate, common cathode, common anode, or series configurations.
• Exposed pad design provides low thermal resistance and efficient die size to board area ratio compared to traditional packages.
• Capable of inspection and probe testing after board mounting due to the new package structure.

Applications

• Output rectification in switching power supplies
• Freewheeling diode applications with inductive loads
• Space-constrained automotive electronics

Procurement Notes

This component is officially discontinued and not recommended for new designs. Verify availability through authorized channels only. Do not assume functional equivalence with other parts without consulting official documentation. Contact onsemi representatives for current product information or valid alternatives.

Selection Notes

Select this part only for legacy system maintenance where the specific DFN8 dual-flag form factor is required. Evaluate the 200V rating and 6A peak current against actual circuit demands. Consider the exposed pad thermal requirements and verify that the discontinuation status does not impact long-term supply chain stability.

Part Context

The NHP620MFD belongs to onsemi's ultrafast rectifier family designed for high-frequency switching applications. It utilizes a clip attach design to minimize height while maintaining performance comparable to larger packages like DPAK. The dual-diode architecture allows designers to save significant PCB real estate compared to using discrete components.
