Procurement Notes
Verify compliance requirements as this specific tin/lead variant may not meet RoHS standards compared to lead-free alternatives. Confirm package integrity and marking accuracy upon receipt. Ensure storage conditions maintain component quality prior to assembly. Cross-reference datasheet specifications against design requirements to validate suitability for the intended operating environment.
Selection Notes
Select this component when a 15 V Zener reference is required in a DO-41 package. Consider the 1 W power rating and thermal constraints for the specific application. Tin/lead plating offers specific soldering characteristics distinct from lead-free options. Verify that the ±5% tolerance aligns with the circuit's precision requirements.
Part Context
This part belongs to the 1N4728A series of 1.0 Watt silicon Zener diodes produced by Central Semiconductor. The series covers a wide voltage range from 3.3 V to 100 V with 5% tolerance. These diodes are marketed for use in demanding industrial, commercial, entertainment, and computer applications requiring reliable voltage regulation.
Replacement Considerations
The 1N4744A BK PBFREE serves as the lead-free equivalent within the same manufacturer lineup. Other manufacturers produce standard 1N4744A variants compatible with these specifications.
