1N4007B-G

Single Diodes Overview

The Comchip Technology 1N4007B-G is a standard recovery rectifier diode designed for general-purpose applications. It features a maximum repetitive peak reverse voltage of 1 kV and an average forward rectified current of 1 A. The device utilizes a DO-41-2 through-hole package, ensuring robust mechanical stability. Key electrical specifications include a maximum forward voltage of 1.1 V at 1 A and a low reverse leakage current of 5 uA at 1000 V. It supports a maximum surge current of 30 A and operates within a junction temperature range from -55 °C to +150 °C.

Single Diodes Feature Summary

• High voltage capability with 1 kV reverse voltage rating
• Standard silicon rectification for general power conversion
• Through-hole mounting for reliable PCB integration

Single Diodes Applications

• AC to DC power supply rectification
• Polarity protection in DC circuits
• Freewheeling diodes in inductive load switching

Single Diodes Procurement Notes

Verify the specific suffix 'B' against the manufacturer's datasheet to confirm any distinct manufacturing lot or marking variations compared to the standard 1N4007. Ensure the DO-41-2 package footprint matches the design requirements. Confirm RoHS compliance status directly with the supplier documentation prior to final procurement decisions.

Single Diodes Selection Notes

Select this component when a standard 1 A, 1 kV rectifier is required for through-hole assembly. The DO-41-2 package offers higher thermal dissipation than surface-mount alternatives. Consider the 1.1 V forward voltage drop for efficiency calculations in low-voltage output stages. Verify that the 30 A surge rating meets the inrush current demands of the target circuit.

Single Diodes Part Context

This part belongs to the widely used 1N400x series of silicon rectifiers, which are industry-standard components for low-frequency power applications. Comchip Technology manufactures this variant to meet general-purpose reliability standards. The 1N4007 designation specifically indicates the 1000 V reverse voltage rating within this family.

Single Diodes Replacement Considerations

Direct pin-compatible substitutes include the 1N4007 from other manufacturers such as ON Semiconductor or Vishay. Ensure replacement parts maintain the same DO-41 package and 1 A/1 kV ratings. Verify that alternative sources offer equivalent reverse leakage and forward voltage characteristics.
