Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the SM4004 part number is utilized by multiple semiconductor manufacturers including Micro Commercial Components (MCC) and Diotec Semiconductor. Confirm that the component matches the required SOD-123FL package dimensions and electrical specifications from the official datasheet before integration into the design.

Single Diodes Selection Notes

Select this component for applications requiring a 1 A current rating and 400 V blocking voltage in a small form factor. Ensure the circuit design accounts for the 3 µs reverse recovery time, as it is classified as a standard recovery diode rather than a fast or ultra-fast type. Verify compatibility with the target PCB footprint for the SOD-123FL package.

Single Diodes Part Context

The SM4004 belongs to the broader family of 1 A silicon rectifier diodes. It serves as a surface-mount alternative to through-hole packages like DO-41, offering similar electrical performance in a reduced physical profile. This series is commonly used in consumer electronics and industrial equipment where space constraints necessitate compact packaging solutions.
