Product details
Overview
1N4569A-1E3/TR from Microsemi is a 6.4 V temperature-compensated Zener reference diode in DO-7 (DO-204AA) glass axial-leaded package, rated for 0.5 mA test current, ±0.0005%/°C temperature coefficient, and 200 Ω dynamic impedance at 25°C. It delivers ultra-stable voltage reference performance for precision instrumentation and aerospace-grade analog circuits.
For engineers reviewing the 1N4569A-1E3/TR datasheet, 1N4569A-1E3/TR pinout, 1N4569A-1E3/TR application, or 1N4569A-1E3/TR equivalent, key selection criteria include its 6.4 V nominal Zener voltage with ±5% tolerance, hermetically sealed DO-7 package, -65°C to +175°C operating range, and military qualification readiness via JAN/JANTX/JANTXV prefixes.
Technical Context
This device belongs to Microsemi's zero-temperature-coefficient Zener family optimized for minimal voltage drift across temperature. Its 0.0005%/°C TC and 6.4 V nominal Zener voltage result from dual-junction temperature compensation architecture, validated over -55°C to +100°C operating range.
The 1N4569A-1E3/TR is specified at IZT = 0.5 mA, with 200 Ω dynamic impedance and ≤2.0 µA reverse leakage at 3 V. It operates within 500 mW maximum power dissipation at 25°C ambient, though optimal stability is achieved below 30 mW per design guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.4 V ±5% at IZT = 0.5 mA - defines primary reference accuracy under standard test conditions |
| Temperature Coefficient | ±0.0005%/°C - enables sub-0.1 mV/°C drift over -55°C to +100°C for high-precision systems |
| Dynamic Impedance (ZZT) | 200 Ω at IZT = 0.5 mA - determines AC noise rejection and load regulation sensitivity |
| Reverse Leakage (IR) | ≤2.0 µA at 3 V - ensures low error contribution in high-impedance bias networks |
| Operating Temperature | -65°C to +175°C - supports extended-range operation in aerospace, downhole, and military environments |
| Package | DO-7 (DO-204AA) glass axial-leaded - hermetically sealed, MIL-STD-750 compliant, tin-lead solderable leads |
| Power Dissipation | 500 mW @ TL = 25°C - sets thermal derating limits for PCB layout and heatsinking |
Pinout & Package
DO-7 (DO-204AA) hermetically sealed glass package with axial leads; cathode identified by band on glass body. Leads are tin-lead plated and solderable per MIL-STD-750 Method 2026. Polarity requires banded end to be positive relative to unbanded end during operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground reference node | Connected to circuit common; establishes reference potential for Zener conduction path |
| Cathode (banded end) | Positive reference output node | Provides stable 6.4 V output when reverse-biased; must be held at higher potential than anode |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low temperature coefficient | ±0.0005%/°C enables <0.03 mV/°C drift over full military temperature range |
| Hermetic glass sealing | DO-7 package ensures long-term parameter stability and moisture resistance in harsh environments |
| MIL-PRF-19500/452 qualification path | Add JAN/JANTX/JANTXV prefix + "-1" suffix (e.g., JANTX1N4569A-1) for screened military-grade versions |
| Tape-and-reel packaging | "TR" suffix indicates EIA-296 compliant tape-and-reel format for automated SMT placement compatibility |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - eliminates need for special handling in assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4574A-1E3/TR | Same 6.4 V / 0.0005%/°C spec but rated at 1.0 mA IZT; 100 Ω ZZT | Better dynamic impedance at higher bias current; requires 2× drive current | Select when circuit can supply 1.0 mA and lower ZZT improves noise rejection |
| 1N4579A-1E3/TR | Same 6.4 V / 0.0005%/°C spec but rated at 2.0 mA IZT; 50 Ω ZZT | Lower impedance and tighter thermal stability at 2.0 mA; higher power draw | Choose when system bias network supports 2.0 mA and lowest possible ZZT is critical |
Compared with 1N4569A-1E3/TR, the 1N4574A-1E3/TR offers lower dynamic impedance at double the test current, while the 1N4579A-1E3/TR further reduces ZZT to 50 Ω but demands 4× more bias current-trade-offs directly impact power budget and noise performance in precision analog designs.

FAQ
What is the Zener test current for 1N4569A-1E3/TR?
The 1N4569A-1E3/TR is specified at a Zener test current (IZT) of 0.5 mA. This current level is used to measure its 6.4 V nominal Zener voltage and 200 Ω dynamic impedance. Operating the 1N4569A-1E3/TR significantly above or below this value may increase temperature coefficient deviation and dynamic impedance, affecting reference stability in precision circuits.
Does 1N4569A-1E3/TR have military qualification options?
Yes, the 1N4569A-1E3/TR can be ordered in qualified military versions by adding appropriate prefixes and suffixes: JANTX1N4569A-1 meets MIL-PRF-19500/452 Class B requirements, while JANTXV1N4569A-1 satisfies Class S screening. These variants retain identical electrical specs but undergo additional environmental and reliability testing per military standards.
What is the maximum operating temperature for 1N4569A-1E3/TR?
The 1N4569A-1E3/TR has a maximum operating temperature of +175°C and a minimum of -65°C. Its DO-7 glass package and internal metallurgical bonding enable this extended range. For optimal voltage-temperature stability, however, the datasheet recommends limiting power dissipation to <30 mW-achievable by biasing near its 0.5 mA IZT.
How does the temperature coefficient of 1N4569A-1E3/TR compare to standard Zeners?
The 1N4569A-1E3/TR achieves ±0.0005%/°C, which is up to 20× lower than typical 6.2 V Zeners (≈0.01%/°C). This ultra-low coefficient results from dual-junction compensation and enables <0.03 mV/°C drift over -55°C to +100°C-critical for uncalibrated systems where thermal drift must remain below ADC LSB thresholds.
Is 1N4569A-1E3/TR compatible with automated assembly processes?
Yes, the "TR" suffix in 1N4569A-1E3/TR denotes EIA-296 compliant tape-and-reel packaging, enabling direct use in pick-and-place machines. Its DO-7 axial leads are tin-lead plated per MIL-STD-750 Method 2026, supporting standard reflow profiles up to 260°C for 10 seconds. The device is also ESD-nonsensitive per MIL-STD-750 Method 1020.
