Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Circuit designs demanding minimal voltage change over broad operating temperature ranges
• Military qualification applications via JAN, JANTX, or JANTXV prefixes

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application, as tighter voltage tolerances require hyphenated suffixes (e.g., -1%, -2%). Confirm military qualifications are requested if needed by adding JAN, JANTX, or JANTXV prefixes. Ensure the correct operating current selection matches the datasheet specifications for optimal stability. Check for tape and reel availability using the TR suffix if required for automated assembly processes.

Single Zener Diodes Selection Notes

Select the 1N4584 when a nominal 6.4 V reference with a low temperature coefficient of 0.0005%/°C is required. This component is suitable for applications needing operation at a 4.0 mA test current. Consider tighter tolerance suffixes if precision exceeds standard JEDEC limits. Verify that the DO-7 through-hole package aligns with your board layout constraints and thermal dissipation needs within the specified power rating.

Single Zener Diodes Part Context

The 1N4584 belongs to the 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microsemi (now Microchip Technology). These devices are designed to provide stable voltage references with minimal drift across wide temperature ranges. The series includes various temperature coefficients and operating currents, with the 1N4584 specifically offering the lowest coefficient in its group at 4.0 mA.

Single Zener Diodes Replacement Considerations
