Product details
Overview
1N4569AUR-1/TR from Microsemi is a hermetically sealed, temperature-compensated Zener reference diode in DO-213AA (MELF) glass package, rated for 5.6 V nominal zener voltage at 0.5 mA test current, with ±0.0005 %/°C temperature coefficient and 5 mV max voltage stability over −55°C to +100°C. It serves as a precision voltage reference in aerospace-grade analog measurement and calibration circuits.
For engineers reviewing the 1N4569AUR-1/TR datasheet, 1N4569AUR-1/TR pinout, 1N4569AUR-1/TR application, or 1N4569AUR-1/TR equivalent, key selection criteria include its ultra-low tempco, hermetic MELF construction, MIL-PRF-19500/452 JANTXV qualification, and operation in low-current (0.5 mA) precision biasing networks.
Technical Context
This device belongs to Microsemi's CDLL4565–CDLL4584A family of metallurgically bonded, double-plug Zener diodes optimized for high-stability voltage referencing. Its compensated structure minimizes drift across −55°C to +100°C, achieving 5 mV max total voltage variation per JEDEC Std. 5.
The 1N4569AUR-1/TR operates at 0.5 mA zener test current with 200 Ω dynamic impedance, exhibits 2 µA reverse leakage at 3 V, and maintains DC power dissipation up to 500 mW at +50°C with 4 mW/°C derating above that ambient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CDLL4569A | Same electrical specs and JANTXV qualification; identical DO-213AA package; differs only in part numbering convention (Microsemi internal vs. JAN-style) | No functional difference; used interchangeably in same schematics and BOMs | Select CDLL4569A when sourcing from legacy Microsemi catalogs or distributor stock aligned with CDLL prefix |
| 1N4569AUR-1 | Same die, same specs, same JANTXV screening; differs only in tape-and-reel packaging (TR suffix denotes reel; no suffix = bulk) | Identical performance; TR version supports automated SMT placement | Choose 1N4569AUR-1/TR for production line compatibility; choose non-TR for prototyping or manual assembly |

FAQ
What is the zener voltage tolerance and test condition for 1N4569AUR-1/TR?
The 1N4569AUR-1/TR has a nominal zener voltage of 5.6 V with ±1% tolerance, measured at a test current of 0.5 mA and ambient temperature of 25°C. This specification is guaranteed under MIL-PRF-19500/452 JANTXV screening and applies across the full qualified temperature range of −55°C to +100°C per JEDEC Std. 5.
Is 1N4569AUR-1/TR compatible with surface-mount reflow processes?
Yes, the 1N4569AUR-1/TR uses a DO-213AA (MELF) glass package qualified for standard SnPb and Pb-free reflow profiles. Its hermetic construction and +6 ppm/°C coefficient of expansion require matching to appropriate PCB substrate materials to prevent mechanical stress-induced parameter shift after soldering.
How does the temperature coefficient of 1N4569AUR-1/TR compare to standard Zener diodes?
The 1N4569AUR-1/TR achieves ±0.0005 %/°C temperature coefficient - over 100× tighter than typical 5.6 V Zeners (which range from ±0.05 %/°C to ±0.1 %/°C). This ultra-low drift is enabled by its double-plug compensated structure and is verified across −55°C to +100°C in JANTXV-tested units.
What is the maximum power dissipation rating for 1N4569AUR-1/TR?
The 1N4569AUR-1/TR is rated for 500 mW DC power dissipation at +50°C ambient, with linear derating of 4 mW/°C above that temperature. At maximum operating ambient of +100°C, usable power drops to 300 mW. This rating assumes proper PCB thermal coupling and applies under JANTXV-qualified conditions.
Does 1N4569AUR-1/TR require external heat sinking in typical applications?
No, the 1N4569AUR-1/TR operates at only 0.5 mA test current, resulting in ~2.8 mW nominal power dissipation at 5.6 V - well below its 500 mW rating. Heat sinking is unnecessary unless used in high-current configurations beyond datasheet-specified conditions, which would void its precision reference performance guarantees.
