Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through the latest product documentation before integration into regulated assemblies. Cross-reference the component marking code with the official identification guide to prevent counterfeit substitution during procurement.

Diode Arrays Selection Notes

Select this component when a quad-diode arrangement is required in a minimal footprint SOT-353-5 package. Ensure the 80 V reverse voltage rating exceeds the maximum circuit transient levels. Verify that the 80 mA forward current capacity meets the load requirements and that the 150 mW power dissipation limit accommodates the thermal environment without excessive heat sinking.

Diode Arrays Part Context

This part belongs to the UMP1N series of small signal switching diodes from ROHM Semiconductor. It is designed for general-purpose applications requiring fast switching speeds in compact surface-mount formats. The quad configuration allows designers to replace multiple discrete diodes with a single component, simplifying PCB layout and assembly processes.

Diode Arrays Replacement Considerations

Consult the official ROHM replacement list for verified substitutes. Ensure any alternative component matches the SOT-353-5 package dimensions and electrical ratings including 80 V reverse voltage and 4 ns recovery time.
