1N4003GP

Single Diodes Overview

The onsemi 1N4003GP is a silicon rectifier diode featuring a glass-passivated junction and DO-41 axial leaded package. It provides a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage rating of 200 V. The device supports a peak non-repetitive forward surge current of 30 A at 8.3 ms. Operating temperatures range from -65 °C to 175 °C, with a maximum instantaneous forward voltage of 1.1 V at 1 A.

Single Diodes Feature Summary

• Glass passivation protects the junction against mechanical stress and moisture
• High thermal stability enables operation up to 175 °C junction temperature
• Robust surge current capability handles transient overload conditions

Single Diodes Applications

• General purpose rectification in power supply circuits
• Reverse polarity protection for DC loads
• Freewheeling diodes in inductive switching applications

Single Diodes Procurement Notes

Verify the specific suffix 'GP' against the manufacturer's official datasheet to confirm the glass passivation feature and exact electrical tolerances. Ensure the component matches the required DO-41 package dimensions and lead specifications for your assembly process. Confirm RoHS compliance status if restricted substances are mandated for your application.

Single Diodes Selection Notes

Select this component when a standard recovery time is sufficient for low-frequency rectification tasks requiring 200 V blocking capability. The 1 A current rating suits moderate power applications where thermal management allows for natural convection cooling. Consider the DO-41 package size constraints and through-hole mounting requirements during PCB layout design.

Single Diodes Part Context

This part belongs to the widely used 1N400x series of general-purpose silicon rectifiers. The '3' designation specifically indicates a 200 V reverse voltage rating, distinguishing it from other variants in the family that offer different voltage levels such as 50 V or 400 V. The GP suffix denotes the glass passivation technology employed by onsemi for enhanced reliability.

Single Diodes Replacement Considerations

Compatible substitutes include Vishay 1N4003GPE/60, Taiwan Semiconductor 1N4003SGR0G, Fairchild 1N4003GPT50R, and MCC 1N4003. Verify that replacement parts maintain identical 1 A current, 200 V voltage, and DO-41 package compatibility.
