Single Diodes Procurement Notes

Verify the manufacturer designation, as onsemi acquired Fairchild Semiconductor's discrete product line. Confirm that the specific part number corresponds to the original Fairchild specifications if legacy compliance is required. Ensure the DO-35 package and RoHS status match the design requirements. Cross-reference datasheets from both entities to confirm parameter consistency for critical applications.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with 30 V reverse voltage capability is needed. The DO-35 package suits designs requiring through-hole assembly. Consider the 500 mA forward current rating for load requirements. The wide operating temperature range makes it suitable for industrial environments where thermal stability is essential for circuit reliability.
