US1NWF-7

Single Diodes Overview

The US1NWF-7 is a 1.0A surface-mount ultra-fast rectifier from Diodes Incorporated, housed in an SOD123F package. It features a peak repetitive reverse voltage of 1200V and a maximum forward current of 1A. The device exhibits an ultra-fast recovery time of 80ns at specified test conditions, with a typical thermal resistance junction-to-ambient of 82°C/W on standard FR-4 substrates. Operating temperature ranges from -55°C to +150°C.

Single Diodes Feature Summary

• Ultra-fast recovery time for high efficiency
• Low leakage current
• Glass passivate die construction
• Low-forward voltage for low power loss

Single Diodes Applications

• Boost diode in power factor correction circuitry
• Secondary rectification and freewheeling for AC-AC converters
• Freewheeling for DC-DC converters
• Flat panel displays
• Switching power supplies/chargers

Single Diodes Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the tape and reel packaging configuration containing 3,000 units per carrier. Confirm that the component meets RoHS 3 compliance standards and is halogen and antimony-free as defined by the manufacturer's green product specifications. Ensure the application environment remains within the specified operating temperature range of -55°C to +150°C.

Single Diodes Selection Notes

Select this component when designing circuits requiring high-voltage blocking capabilities up to 1200V combined with rapid switching speeds. The SOD123F package provides a small form factor suitable for space-constrained consumer applications. Consider the thermal characteristics and derating curves if the ambient temperature exceeds standard operating limits or if continuous current approaches the 1A rating.

Single Diodes Part Context

This part belongs to the US1NWF series of ultra-fast rectifiers manufactured by Diodes Incorporated. It is designed specifically for high-temperature conditions and high-reliability applications. An automotive-compliant variant, designated US1NWFQ, is available under a separate datasheet for customers requiring specific automotive qualification standards beyond standard JEDEC references.
