Procurement Notes
Verify the manufacturer origin, as this component has been produced by multiple entities including Microsemi and Microchip Technology. Confirm the specific datasheet revision and package marking to ensure compatibility with existing designs. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a stable 12.8V reference with minimal temperature drift is required. The DO-35 package is suitable for through-hole mounting. Consider the ±5% voltage tolerance and the specific temperature coefficient range during circuit design. This part is ideal for applications demanding low noise performance alongside thermal stability.
Part Context
The 1N4896A belongs to the JEDEC registered 1N4896 through 1N4915 series of temperature-compensated Zener diodes. These components are designed to provide highly stable voltage references over a wide temperature range. The series is widely used in instrumentation and measurement equipment where accuracy and reliability are critical.
Replacement Considerations
Direct substitutes within the same series include other 1N48xx temperature-compensated Zener diodes with similar voltage ratings. Verify pinout compatibility and power dissipation limits before substitution. Cross-reference with Microsemi or Microchip Technology official cross-reference lists for confirmed equivalents.
