Product details
Overview
1N827AUR/TR from Microsemi is a surface-mount, temperature-compensated Zener reference diode in DO-213AA (MELF) glass package, delivering 6.2 V nominal Zener voltage ±5% at 7.5 mA test current, with 10 Ω dynamic impedance and 0.001 %/°C temperature coefficient over –55 °C to +100 °C. It serves as a precision voltage reference in high-stability analog instrumentation and military-grade power regulation circuits.
For engineers reviewing the 1N827AUR/TR datasheet, 1N827AUR/TR pinout, 1N827AUR/TR application, or 1N827AUR/TR equivalent, key selection criteria include its MIL-PRF-19500/159 qualification level (JANTXV), hermetic glass construction, RoHS-compliant matte-tin plating, and tight thermal drift performance under varying load and temperature conditions.
Technical Context
This device belongs to Microsemi's bonded-Zener family optimized for minimal voltage drift across wide temperature ranges. Its double-plug metallurgical bond and internal compensation structure enable ultra-low temperature coefficients down to 0.001 %/°C - achieved only at the specified 7.5 mA operating current and validated over –55 °C to +100 °C.
The 1N827AUR/TR uses a cathode-banded polarity configuration and requires forward-bias orientation (banded end positive) for proper regulation. Its 100 pF typical junction capacitance and non-ESD-sensitive design per MIL-STD-750 Method 1020 support use in low-noise, high-reliability analog signal chains without external shielding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 5.89–6.51 V at 7.5 mA - ensures stable 6.2 V reference within ±5% tolerance for precision biasing |
| Temp Coefficient | 0.001 %/°C - limits voltage drift to ±9 mV over –55 °C to +100 °C |
| Zener Impedance | 10 Ω at 7.5 mA - maintains regulation accuracy under small-signal load variations |
| Max Reverse Current | 2 µA at 3 V - guarantees low leakage in high-impedance reference nodes |
| Power Dissipation | 500 mW - supports continuous operation at 7.5 mA with <50 mW actual dissipation |

Pinout & Package
DO-213AA (MELF) glass package: hermetically sealed, axial cylindrical form factor with tin-lead or RoHS-compliant matte-tin plating; cathode identified by single black band; polarity requires banded end to be positive during operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-side return path; reverse-biased during regulation |
| Cathode | Regulated output node | Banded end supplies stable 6.2 V reference; must be held at higher potential than anode |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N827UR/TR | Same 6.2 V nominal, same DO-213AA package, but 15 Ω ZZT instead of 10 Ω | Suitable where tighter impedance is not required; lower cost commercial variant | Select when 15 Ω ZZT meets system regulation spec and RoHS compliance is not mandatory |
| 1N829AUR/TR | Identical construction and RoHS compliance, but 6.55 V nominal and 0.0005 %/°C TC | Used where higher reference voltage and ultra-low drift are needed, e.g., metrology-grade instruments | Choose for applications demanding <5 mV total drift over temperature - requires revalidation of bias network gain |
Compared with 1N827UR/TR, the 1N827AUR/TR offers lower impedance for improved load regulation; compared with 1N829AUR/TR, it provides a lower nominal voltage with slightly relaxed TC - enabling direct substitution in 6.2 V designs without circuit recalibration.

FAQ
What is the Zener voltage tolerance of the 1N827AUR/TR?
The 1N827AUR/TR has a Zener voltage range of 5.89 V to 6.51 V at 7.5 mA test current, corresponding to a ±5% tolerance around the nominal 6.2 V rating. This tolerance is guaranteed per the Electrical Characteristics table in Microsemi's T4-LDS-0220-1 datasheet and applies to all units meeting JANTXV qualification.
Is the 1N827AUR/TR RoHS compliant?
Yes, the 1N827AUR/TR is RoHS compliant, indicated by the "e3" suffix in its nomenclature. It features annealed matte-tin plating per MIL-STD-750 Method 2026 and is qualified for commercial applications only - RoHS compliance is not offered for JAN/JANTX/JANTXV/JANS military grades of this device.
What does the "TR" suffix mean in 1N827AUR/TR?
The "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape. This format supports automated SMT placement and is the standard shipping configuration for volume orders of the 1N827AUR/TR at Aetrix Electronics.
What is the maximum operating temperature for the 1N827AUR/TR?
The 1N827AUR/TR has a junction and storage temperature range of –55 °C to +175 °C. Its voltage stability specification (±9 mV ∆VZT) is validated over –55 °C to +100 °C, making it suitable for high-reliability applications including avionics and downhole industrial electronics.
How does the 1N827AUR/TR differ from the 1N827UR/TR?
The 1N827AUR/TR differs from the 1N827UR/TR primarily in Zener impedance (10 Ω vs. 15 Ω) and RoHS compliance (e3 plating vs. tin-lead). Both share identical 6.2 V nominal voltage, DO-213AA package, and JANTXV qualification - the "A" in 1N827AUR/TR explicitly denotes the 10 Ω ZZT option and RoHS-compliant termination.
