1N3823A-1

Single Zener Diodes Overview

The 1N3823A-1 is a silicon voltage regulator diode manufactured by Microchip Technology, designed for high-reliability applications. It operates within the MIL-PRF-19500/115 specification series and features a hermetically sealed axial-leaded glass DO-41 package. The device provides a nominal Zener voltage of 3.9 V at a test current of 64 mA, with a maximum dynamic impedance of 9 ohms. It supports a power handling capability of 1 W and is available in JAN, JANTX, and JANTXV quality levels to meet stringent military standards.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-leaded glass DO-41 package construction
• Qualified per MIL-PRF-19500/115 for high reliability
• Available in JAN, JANTX, and JANTXV military grades

Single Zener Diodes Applications

• Military aerospace voltage regulation circuits
• High-reliability industrial power supplies
• Spacecraft electronic subsystems requiring strict environmental sealing

Single Zener Diodes Procurement Notes

Verify the specific suffix (JAN, JANTX, or JANTXV) against the purchase order, as these denote different quality assurance levels under MIL-PRF-19500/115. Confirm that the DO-41 axial leaded package matches the PCB footprint requirements. Ensure the supplier provides traceability documentation consistent with military procurement standards for this component type.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V reference is required in harsh environments. The DO-41 glass package offers superior hermeticity compared to plastic alternatives. Consider the JANTXV grade if the application demands the highest level of screening and reliability defined by the military specification, ensuring compatibility with existing circuit designs utilizing standard Zener regulators.

Single Zener Diodes Part Context

This part belongs to the 1N3821A-1 through 1N3828A-1 series of silicon voltage regulator diodes. The series shares common electrical characteristics and packaging styles but varies in nominal Zener voltage. The 1N3823A-1 specifically targets the 3.9 V range, fitting into the broader portfolio of high-reliability discrete semiconductors produced for defense and aerospace markets.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' parts qualified to MIL-PRF-19500/115 with identical 3.9 V Zener voltage and DO-41 package. Verify that any replacement maintains the same hermetic seal and meets the required leakage and impedance specifications.
