• Industrial equipment operating under extreme thermal conditions

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as JAN, JANTX, or JANTXV denote different quality levels and tolerance grades under the MIL-PRF-19500/115 specification. Confirm that the required package type matches the DO-41 axial lead configuration. Ensure that procurement channels provide traceability documentation consistent with military-grade component sourcing requirements.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference is needed in a ruggedized axial package. The 1 W power rating allows for significant current handling compared to lower-power equivalents. Consider the wide temperature capability for applications where standard commercial parts would fail. Verify that the system design accommodates the physical dimensions of the DO-41 glass envelope.

Single Zener Diodes Part Context

This part belongs to the 1N3821A-1 through 1N3828A-1 series of silicon voltage regulators manufactured by Microchip Technology. The series offers various Zener voltages while maintaining consistent mechanical and electrical characteristics defined by the MIL-PRF-19500/115 standard. These components are engineered for high-reliability applications where long-term stability and environmental resistance are critical.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' parts conforming to MIL-PRF-19500/115 with identical 5.1 V Zener voltage and DO-41 packaging. Equivalent commercial alternatives may exist but must be evaluated for temperature range and hermetic sealing requirements.
