Single Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against datasheet specifications. Confirm RoHS compliance status via the E3 suffix designation. Validate that the DO-41 package dimensions match design requirements. Ensure procurement channels are authorized to prevent counterfeit components.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating is required alongside a 1.0 A continuous current capacity. The glass-passivated construction provides enhanced environmental stability compared to non-passivated alternatives. Verify thermal management capabilities align with the specified junction temperature limits during operation.

Single Diodes Part Context

This part belongs to the 1N4245GP through 1N4249GP series, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 200 V to 1000 V. All variants share identical forward current, surge capability, and packaging characteristics. The series utilizes the Superectifier technology for improved reliability in standard rectification tasks.

Single Diodes Replacement Considerations

Direct substitutes include other 400 V, 1 A glass-passivated rectifiers in the DO-41 package. Verify electrical parameters such as forward voltage and leakage current match or exceed original specifications. Ensure mechanical compatibility with existing PCB layouts and lead spacing.
