Product details
Overview
1N823AUR from Microsemi is a surface-mount, temperature-compensated Zener reference diode with nominal 6.2 V output, ±5% tolerance, 0.005%/°C temperature coefficient, 10 Ω zener impedance at 7.5 mA, and DO-213AA (MELF) glass package-used in precision voltage references for instrumentation and analog signal conditioning.
For engineers reviewing the 1N823AUR datasheet, 1N823AUR pinout, 1N823AUR application, or 1N823AUR equivalent, key selection criteria include its ultra-low TC (0.005%/°C), tight thermal stability over –65°C to +175°C, low 2.0 µA reverse leakage at 3 V, and suitability for high-reliability analog reference designs requiring minimal drift.
Technical Context
The 1N823AUR operates as a two-terminal, cathode-banded, forward-polarity reference diode-biased with the banded end positive-optimized for 7.5 mA test current to achieve specified TC and impedance. Its hermetically sealed DO-213AA glass construction ensures stable operation across military-grade temperature extremes.
It delivers 6.2 V nominal regulation with ≤48 mV total voltage drift from –55°C to +100°C and exhibits typical capacitance ≤100 pF, supporting low-noise analog referencing without parasitic coupling. The device is RoHS-compliant (e3 suffix) and ESD-nonsensitive per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 5.9–6.5 V @ 7.5 mA - defines usable reference range under standard bias; center nominal 6.15 V supports precision calibration. |
| Temp Coefficient | 0.005 %/°C - enables <±0.5 mV/°C drift in critical analog circuits operating across wide ambient ranges. |
| Zener Impedance | 10 Ω @ 7.5 mA - ensures minimal output voltage shift (<75 mV) under ±7.5 mA load variation. |
| Reverse Leakage | 2.0 µA @ 3 V - guarantees negligible error contribution in high-impedance reference divider networks. |
| Operating Temp | –65°C to +175°C - supports deployment in aerospace, downhole, and industrial control environments. |
| Power Dissipation | 500 mW @ TL = 25°C - allows safe operation at full rating with adequate board-level thermal relief. |
| Capacitance | ≤100 pF - minimizes high-frequency noise injection into sensitive ADC reference inputs. |
Pinout & Package
DO-213AA (MELF) glass package: cylindrical, hermetically sealed, axial-leaded surface-mount form factor with cathode band marking; 1.60–1.70 mm diameter, 3.30–3.70 mm length; weight 0.04 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased operation requires cathode at higher potential. |
| Cathode | Reference output node | Banded end; supplies stable 6.2 V when biased at 7.5 mA; polarity must be observed to avoid damage. |
Key Features
| Feature | Design Value |
|---|---|
| Temperature compensation | 0.005%/°C TC enables sub-millivolt drift over –55°C to +100°C, critical for metrology-grade references. |
| Hermetic DO-213AA packaging | Eliminates moisture-induced parameter shift and supports long-term stability in harsh environments. |
| Low 2.0 µA IR at 3 V | Reduces loading error in high-Z feedback networks and improves accuracy of buffered reference outputs. |
| Nonsensitive to ESD | MIL-STD-750 Method 1020 compliance removes need for handling precautions during SMT assembly. |
| RoHS-compliant (e3) | Tin-plated terminals meet environmental regulations without sacrificing solderability or reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 | 6.2 V ±5%, 40 Ω ZT, 0.02%/°C TC, SOT-23 package | Higher TC and impedance; unsuitable for metrology or extended-temp use | Lower-cost option for commercial-grade 6.2 V reference where drift <±2 mV/°C is acceptable |
| 1N829AUR | 6.2 V ±5%, 10 Ω ZT, 0.0005%/°C TC, same DO-213AA package | Superior TC performance but higher cost; tighter spec for ultra-stable applications | Select when <±5 mV total drift over –55°C to +100°C is required-e.g., calibration standards or satellite payloads |
Compared with BZX84-C6V2 and 1N829AUR, the 1N823AUR offers balanced performance: lower TC than standard Zeners yet more cost-effective than ultra-stable variants, making it optimal for industrial and aerospace analog references needing verified 0.005%/°C stability in DO-213AA form.

FAQ
What is the nominal Zener voltage and tolerance of the 1N823AUR?
The 1N823AUR has a nominal Zener voltage of 6.2 V with a tolerance of ±5% (5.9–6.5 V range) when tested at 7.5 mA. This specification is defined per JEDEC registration and confirmed in Microsemi's official datasheet Rev B. The 1N823AUR achieves this voltage with minimal drift due to its temperature-compensated design and hermetic DO-213AA packaging.
What is the temperature coefficient (TC) of the 1N823AUR, and over what range is it specified?
The 1N823AUR has an effective temperature coefficient of 0.005 %/°C, specified over the –55°C to +100°C operating range. This value reflects the maximum TC measured per JEDEC testing methodology and is validated by the 48 mV maximum ΔVZ over that interval. The 1N823AUR maintains this TC performance due to its internal temperature-compensation structure.
What package type and marking does the 1N823AUR use?
The 1N823AUR uses the DO-213AA (MELF) glass surface-mount package with a cathode band marking on the banded end. It is hermetically sealed, weighs 0.04 g, and conforms to dimensions A = 1.60–1.70 mm and B = 3.30–3.70 mm. The 1N823AUR marking includes the cathode band only-no alphanumeric laser marking-as confirmed in Microsemi's mechanical drawings.
Is the 1N823AUR RoHS-compliant, and what plating is used on its terminals?
Yes, the 1N823AUR is RoHS-compliant when ordered with the e3 suffix, using annealed matte tin plating on terminals per MIL-STD-750 Method 2026. This plating ensures reliable solderability and corrosion resistance. The 1N823AUR e3 variant meets EU RoHS Directive 2011/65/EU requirements without compromising electrical or thermal performance.
What is the maximum reverse leakage current for the 1N823AUR, and at what test condition?
The 1N823AUR has a maximum reverse leakage current (IR) of 2.0 µA at 3 V reverse bias, measured at 25°C. This low leakage ensures minimal error in high-impedance reference networks and contributes to the 1N823AUR's suitability for precision analog applications such as data acquisition and sensor signal conditioning.
