Product details
Overview
JANS1N823UR-1/TR from Microsemi is a hermetically sealed, surface-mount, temperature-compensated Zener reference diode in DO-213AA (MELF) package, delivering 6.2 V nominal Zener voltage ±5% at 7.5 mA test current, with 48 mV max voltage drift over –55 °C to +100 °C and 0.005 %/°C effective temperature coefficient - used in precision instrumentation voltage references requiring military-grade stability.
For engineers reviewing the JANS1N823UR-1/TR datasheet, JANS1N823UR-1/TR pinout, JANS1N823UR-1/TR application, or JANS1N823UR-1/TR equivalent, key selection criteria include Zener impedance (15 Ω), reverse leakage (≤2 µA @ 3 V), power dissipation (500 mW), junction temperature range (–55 °C to +175 °C), and MIL-PRF-19500/159 JANS qualification for high-reliability aerospace and defense systems.
Technical Context
The JANS1N823UR-1/TR implements a double-plug, metallurgically bonded Zener structure within a hermetic glass DO-213AA case, enabling stable regulation under thermal stress. Its temperature compensation is achieved via internal junction design rather than external circuitry, yielding low TC without auxiliary components.
It operates exclusively in reverse-bias breakdown mode with cathode-band polarity marking, requires 7.5 mA nominal bias for specified TC and VZ stability, and exhibits ≤100 pF typical capacitance - suitable for low-noise analog reference paths where parasitic coupling must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 5.89–6.51 V @ 7.5 mA - defines tight 6.2 V nominal reference with ±5% tolerance for calibration-critical circuits |
| Temp Coefficient | 0.005 %/°C - enables <48 mV total drift across –55 °C to +100 °C, meeting MIL-spec stability requirements |
| Zener Impedance | 15 Ω @ 7.5 mA - ensures minimal output voltage shift under load transients in precision reference designs |
| Max Reverse Leakage | ≤2 µA @ 3 V - guarantees negligible error contribution in high-impedance feedback or sensing nodes |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous operation at 7.5 mA (≤50 mW) with ample thermal margin |
| Junction Temp Range | –55 °C to +175 °C - qualified for extended environmental operation in avionics and space-qualified electronics |
Pinout & Package
DO-213AA (MELF) glass package: hermetically sealed, axial cylindrical form with tin-lead plating per MIL-STD-750 Method 2026; cathode identified by single black band; no discrete pins - two terminals only (anode and cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reference Output Terminal | Connected to regulated positive reference node; must be held at higher potential than anode during operation |
| Anode (unbanded end) | Return / Ground Reference | Serves as circuit common; reverse-bias current flows from cathode to anode in regulation mode |

|---|---|
| Hermetic DO-213AA construction | Eliminates moisture-induced parameter drift and long-term degradation in harsh environments |
| Double-plug metallurgical bond | Ensures mechanical robustness and thermal cycle reliability exceeding MIL-PRF-19500/159 JANS level |
| Temperature-compensated Zener junction | Delivers 0.005 %/°C TC without external compensation networks or trimming resistors |
| MIL-PRF-19500/159 JANS qualification | Validated for use in Class S (space) and Class H (high-reliability) applications per DoD requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N823UR-1 | Same electrical specs; JANTXV qualification (lower screening rigor than JANS, no burn-in required) | Approved for Class B (ground) and Class C (commercial) systems; not rated for spaceflight | Select when full JANS-level reliability testing is unnecessary but MIL-PRF-19500 compliance is required |
| 1N823UR-1 | Commercial-grade version; identical DO-213AA package and VZ/TC specs, but no MIL qualification or hermeticity verification | Restricted to non-safety-critical industrial instrumentation; RoHS-compliant plating available | Choose for cost-sensitive prototyping or terrestrial test equipment where long-term parametric stability is secondary to unit cost |
Compared with JANS1N823UR-1/TR, JANTXV1N823UR-1 offers reduced test coverage and lower lifecycle assurance, while 1N823UR-1 lacks military screening and hermetic validation - making JANS1N823UR-1/TR the only option qualified for mission-critical space and airborne platforms demanding zero parametric drift over 15+ years.

FAQ
What is the Zener voltage tolerance and test condition for JANS1N823UR-1/TR?
JANS1N823UR-1/TR has a Zener voltage range of 5.89 V to 6.51 V, corresponding to a nominal 6.2 V ±5% tolerance, measured at a Zener test current (IZT) of 7.5 mA per MIL-PRF-19500/159. This specification is verified during JANS-level screening and applies across the full qualified temperature range.
Does JANS1N823UR-1/TR require external temperature compensation?
No, JANS1N823UR-1/TR incorporates intrinsic temperature compensation via its double-plug metallurgical Zener junction design, achieving an effective temperature coefficient of 0.005 %/°C without any external components. This eliminates the need for thermistors, op-amps, or trimming networks in reference designs using JANS1N823UR-1/TR.
What is the maximum reverse leakage current for JANS1N823UR-1/TR?
JANS1N823UR-1/TR specifies a maximum reverse leakage current (IR) of 2 µA at 3 V reverse bias and 25 °C, per its MIL-PRF-19500/159 qualification. This low leakage ensures minimal loading error in high-impedance reference divider networks and precision ADC biasing circuits using JANS1N823UR-1/TR.
Is JANS1N823UR-1/TR compatible with lead-free reflow processes?
JANS1N823UR-1/TR uses traditional tin-lead plating per MIL-STD-750 Method 2026 and is qualified for soldering at 260 °C for 10 seconds, but it is not RoHS compliant. For lead-free assembly, JANS1N823UR-1/TR requires controlled thermal profiling to avoid glass-to-metal seal stress; Microsemi does not offer a RoHS-compliant JANS variant of JANS1N823UR-1/TR.
How is polarity marked on JANS1N823UR-1/TR?
JANS1N823UR-1/TR uses a single black cathode band on the DO-213AA glass body to indicate polarity. The banded end is the cathode and must be biased positively relative to the unbanded (anode) end during normal Zener regulation operation - correct orientation is essential to achieve specified VZ, TC, and impedance performance in circuits using JANS1N823UR-1/TR.
