Procurement Notes

This component is officially marked as obsolete with no alternate part available from the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct procurement from Diodes Incorporated. Confirm specific packaging suffixes and manufacturing dates when sourcing from third-party distributors.

Selection Notes

Designers must account for the discontinued status when selecting this component for new products. Verify that existing inventory meets long-term supply requirements. Consider evaluating alternative manufacturers offering similar specifications if future production continuity is required.

Part Context

The 1N4755A belongs to the 1N4728A through 1N4761A series of 1.0W Zener diodes produced by Diodes Incorporated. This series covers a wide voltage range from 3.3V to 75V. The -T suffix indicates tape and reel packaging, typically supplied in quantities of 5,000 units per reel.

Replacement Considerations

Diodes Incorporated has designated this part as obsolete with no official alternate provided. Cross-referencing with other manufacturers may be necessary, but electrical parameters such as impedance and leakage must be verified against original datasheet specifications.
