JAN1N4954C

Single Zener Diodes Overview

The JAN1N4954C is a military-grade Zener diode manufactured by Microchip Technology. It provides a nominal voltage regulation of 6.8V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 5W and operates within an extended temperature range from -65°C to +175°C. Designed for through-hole mounting, it utilizes an axial lead configuration housed in the DO-201AE (E) package. This component is specifically engineered for high-reliability applications requiring stable voltage reference under extreme environmental conditions.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required ±2% tolerance variant against the official datasheet. Confirm RoHS exemption status as military parts often fall outside standard compliance. Validate that the DO-201AE package dimensions match your PCB footprint requirements. Ensure the supplier provides traceability documentation consistent with military procurement standards.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and wide thermal stability are critical. Compare the 5W power rating against your circuit's thermal management capabilities. Consider the axial package constraints for board layout. Verify that the 6.8V breakdown voltage aligns with your system's reference needs without excessive series resistance losses.

Single Zener Diodes Part Context

This part belongs to the JAN1N49xx series of hermetically sealed Zener diodes. It shares the same physical package and general electrical characteristics as commercial variants but meets stricter military screening and quality assurance standards. The series covers various voltage ratings, with the JAN1N4954C specifically targeting the 6.8V regulation niche.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JAN1N4954C equivalents from qualified manufacturers. Commercial 1N4954B or 1N4954 may serve if military grade is not required. Verify pinout compatibility and ensure thermal performance matches the original design specifications.
