1N4007

Single Diodes Overview

The onsemi 1N4007 is an axial-lead, glass-passivated standard recovery rectifier designed for general-purpose low-power applications. It features a single diffused junction silicon construction housed in a DO-41 (CASE 59-10) epoxy molded package with corrosion-resistant terminal leads. The device supports a maximum average rectified forward current of 1.0 A and withstands a peak repetitive reverse voltage of 1000 V. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 1.0 A and a non-repetitive peak surge current rating of 30 A. Operating temperatures range from -65°C to +150°C.

Single Diodes Feature Summary

• Glass-passivated p-n junction construction provides high reliability and ruggedness under various operating conditions.
• Epoxy molding compound meets UL flammability classification 94V-0 for enhanced safety.
• Cathode polarity is clearly indicated by a visible band on the component body.
• Terminal leads are readily solderable and resistant to external surface corrosion.

Single Diodes Applications

• General-purpose rectification in low-power electronic circuits
• AC-to-DC conversion in power supply input stages
• Reverse polarity protection in DC circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing, as it determines the shipping format such as bulk bags or tape and reel quantities. Confirm that the part number matches the required voltage rating within the 1N400x series. Check for Pb-Free status if environmental compliance is mandatory for the assembly process. Ensure the manufacturer source is authorized to guarantee datasheet accuracy and traceability.

Single Diodes Selection Notes

Select this component for applications requiring robust standard recovery performance with a 1000 V blocking capability. Consider the thermal resistance values provided for different mounting methods when designing heat dissipation strategies. Verify that the 1.0 A continuous current rating aligns with the circuit's load requirements. Evaluate the package dimensions against available PCB real estate before finalizing the design.

Single Diodes Part Context

This device belongs to the 1N400x family of axial-lead rectifiers manufactured by onsemi. The family includes variants with lower reverse voltage ratings, ranging from 50 V to 800 V, sharing identical mechanical and thermal characteristics. The 1N4007 specifically represents the highest voltage option in this standard series, offering 1000 V blocking capability while maintaining the same 1 A current handling capacity.

Single Diodes Replacement Considerations

Cross-reference other manufacturers' 1N4007 equivalents to ensure pinout compatibility and matching electrical specifications. Verify that substitute components meet the same thermal and mechanical standards for direct replacement.
