Single Diodes Procurement Notes

Verify the specific manufacturer designation as SMC Diode Solutions may utilize different suffixes or internal part numbers compared to standard JEDEC designations. Confirm RoHS compliance status and packaging options directly with authorized distributors. Ensure the datasheet matches the exact lot code and revision required for your application specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with 200 V blocking voltage and 1 A continuous current rating is required. The DO-41 package offers robust mechanical stability for through-hole assembly. Consider thermal management requirements given the 175°C junction temperature limit. Verify that the 2 µs typical reverse recovery time meets the switching speed requirements of the target circuit.

Single Diodes Part Context

The 1N4003G belongs to the widely recognized 1N400x series of general-purpose silicon rectifier diodes. This series is standardized across multiple manufacturers, ensuring interchangeability based on JEDEC specifications. The 'G' suffix typically denotes a green (RoHS compliant) variant or specific packaging configuration depending on the manufacturer's coding system. It serves as a fundamental component in AC-to-DC conversion stages.

Single Diodes Replacement Considerations

Direct replacements include 1N4003 from other major manufacturers such as Vishay, Diodes Incorporated, and Taiwan Semiconductor. Ensure substitute parts maintain the same DO-41 package dimensions and electrical ratings. Verify that alternative sources offer equivalent surge current capabilities and reverse leakage specifications.
