Procurement Notes
Verify that the ordering suffix matches the required configuration, as suffixes may indicate specific packaging or compliance variations without altering electrical function. Confirm the manufacturer designation is Microchip Technology. Ensure the package type corresponds to DO-41 and check for RoHS compliance status if required by assembly specifications. Cross-reference datasheet parameters against application requirements.
Selection Notes
Select this component when a stable 3.3V reference is needed in high-reliability environments. The DO-41 package suits through-hole mounting processes. Consider the 1W power rating for thermal management needs. Verify the 5% tolerance meets circuit precision requirements. The extended temperature range supports operation in demanding industrial conditions.
Part Context
This part belongs to the 1N47xxA series of one-watt Zener diodes manufactured by Microchip Technology. The series offers a wide voltage range from 3.3V to 100V. These diodes are characterized by their glass passivation and double-slug construction, providing consistent performance across various industrial and commercial applications requiring reliable voltage regulation.
Replacement Considerations
Equivalent parts include the 1N4728A and 1N4728AG from other manufacturers such as NXP or Microsemi. Ensure replacement components match the 3.3V Zener voltage, 1W power rating, and DO-41 package dimensions. Verify electrical characteristics like knee impedance and temperature coefficients align with original design specifications.
