Procurement Notes

This component is officially marked as obsolete and discontinued by Diodes Incorporated. No alternate part numbers are provided by the manufacturer. Verification of current availability requires checking distributor channels for remaining stock or qualified cross-references from other manufacturers, as direct procurement from Diodes is no longer possible.

Selection Notes

Designers should note that this specific part number is discontinued. Selection of an alternative requires matching the 16V nominal voltage, 1W power rating, and DO-41 axial package dimensions. Verify thermal resistance characteristics and impedance specifications against the new component datasheet to ensure circuit performance compatibility.

Part Context

The 1N4745A belongs to the 1N4728A through 1N4761A series of silicon planar power Zener diodes. This series covers a voltage range from 3.3V to 75V. The -T suffix indicates tape and reel packaging containing 5,000 units per reel.

Replacement Considerations

Diodes Incorporated lists no official alternate part number for this obsolete device. Engineers must source equivalent components from other manufacturers that meet the 16V, 1W, and DO-41 specifications.
