1N4003B-G

Single Diodes Overview

The Comchip Technology 1N4003B-G is a general-purpose silicon rectifier diode designed for AC-to-DC conversion applications. It features a maximum average forward rectified current of 1.0 ampere and a peak repetitive reverse voltage rating of 200 volts. The device utilizes a DO-201AD axial leaded package, providing robust mechanical stability for through-hole mounting. Key electrical characteristics include a maximum RMS rectifying voltage of 140 volts and a non-repetitive peak forward surge current capability of 30 amperes at 60 Hz. These specifications ensure reliable operation in standard power supply circuits requiring moderate voltage blocking capabilities.

Single Diodes Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm RoHS compliance status and exact pinout configuration. Ensure the DO-201AD package dimensions match your board layout requirements. Cross-reference the part number with authorized distributors to validate authenticity and traceability documentation before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 200V reverse voltage rating is required alongside a 1A continuous forward current capacity. Consider the thermal resistance characteristics of the DO-201AD package for heat dissipation needs. Evaluate the reverse recovery time specifications if high-frequency switching applications are involved, ensuring compatibility with the circuit's operational frequency constraints.

Single Diodes Part Context

This diode belongs to the standard 1N400x series of general-purpose rectifiers, widely used in low-power electronic devices. The 'B' designation typically indicates a specific manufacturing batch or minor variant within the Comchip portfolio, while 'G' often denotes environmental compliance. This series serves as a fundamental component in consumer electronics and industrial control systems requiring basic rectification functions.

Single Diodes Replacement Considerations

Direct replacements include the 1N4003 from other manufacturers such as Vishay or ON Semiconductor, provided they meet the same 200V PIV and 1A IF ratings. Verify that substitute components utilize compatible DO-201AD packages and maintain identical electrical parameters to ensure seamless integration without circuit modification.
