Single Diodes Procurement Notes

Verify the specific marking code T4 on the component case to confirm alignment with the original MDD specification sheet. Ensure that the procurement documentation explicitly references the NextGen Components specification sheet N0729-SOD1234148WST4 Rev A0. Confirm RoHS compliance status matches the required environmental standards for your manufacturing process before finalizing orders.

Single Diodes Selection Notes

Select this component when a compact SOD-123 footprint is required for general-purpose switching tasks. The 150mA current rating and 100V reverse voltage provide adequate margins for standard low-power digital logic interfaces. Consider the 4ns recovery time for applications requiring rapid signal transitions without significant delay.

Single Diodes Part Context

This part belongs to the SMD Fast Switching Diodes SOD-123 series manufactured by MDD. It serves as a surface-mount alternative to traditional through-hole switching diodes, offering reduced board space requirements while maintaining comparable electrical performance metrics for general electronic circuit designs.

Single Diodes Replacement Considerations

Cross-reference with other SOD-123 packaged 1N4148 variants. Verify pinout compatibility and ensure equivalent reverse voltage and current ratings are met by potential substitute components.
