Product details
Overview
JANS1N6123AUS/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade silicon Zener diode rated for 12 V nominal breakdown voltage at 25 mA test current, with ±5% tolerance, 1.5 W power dissipation, and operating temperature range of −65 °C to +175 °C - used in precision voltage reference and overvoltage protection circuits in aerospace power conditioning systems.
For engineers reviewing the JANS1N6123AUS/TR datasheet, JANS1N6123AUS/TR pinout, JANS1N6123AUS/TR application, or JANS1N6123AUS/TR equivalent, key selection criteria include Zener voltage accuracy, high-temperature stability, hermetic package reliability, MIL-PRF-19500/418 qualification, and low dynamic impedance under transient load conditions.
Technical Context
This device operates as a two-terminal voltage-regulating element relying on controlled reverse-biased avalanche breakdown. Its Zener voltage is specified at 25 mA and exhibits <0.01 %/°C temperature coefficient over −55 °C to +125 °C, with dynamic impedance of 12 Ω max at 25 mA.
Designed to meet MIL-PRF-19500/418 Class H requirements, JANS1N6123AUS/TR features gold-plated leads, glass-passivated junction, and screening including burn-in, thermal cycling, and lot acceptance testing per MIL-STD-750.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6123AUS | Same Zener voltage and package, but qualified to MIL-PRF-19500/418 Class B (lower screening level) | Lacks full Class H burn-in and thermal cycling; suitable for non-critical subsystems | Select JANTX1N6123AUS only if mission-critical reliability is not required and cost reduction is prioritized |
| 1N6123US | Commercial-grade version; no MIL qualification, wider voltage tolerance (±10%), max temp +150 °C | Not approved for spaceflight or defense platforms; limited to industrial prototypes | Choose 1N6123US for lab validation where environmental robustness is secondary to procurement speed |
Compared with JANTX1N6123AUS and 1N6123US, JANS1N6123AUS/TR offers the highest assurance of parametric stability and survivability in extended-duration, high-radiation, or thermally cycled deployments - critical where field replacement is impossible.

FAQ
What is the Zener voltage tolerance for JANS1N6123AUS/TR?
JANS1N6123AUS/TR has a Zener voltage tolerance of ±5% at 25 mA test current, as verified per MIL-PRF-19500/418 Class H test requirements. This tight tolerance ensures predictable clamping behavior in safety-critical power monitoring circuits where deviation beyond ±0.6 V could trigger false fault detection.
Is JANS1N6123AUS/TR qualified for space applications?
Yes, JANS1N6123AUS/TR is screened to MIL-PRF-19500/418 Class H and commonly used in LEO satellite power subsystems. Its hermetic DO-41 package, gold-plated leads, and radiation-tolerant junction structure meet typical space-grade component requirements, though individual mission approval requires additional ESA ECSS-Q-ST-60-13C analysis.
What is the maximum operating temperature of JANS1N6123AUS/TR?
JANS1N6123AUS/TR is rated for continuous operation from −65 °C to +175 °C. This extended range is validated through thermal cycling and high-temperature life testing per MIL-STD-750 Method 1082, making it suitable for downhole oilfield tools and jet engine-mounted electronics where ambient temperatures exceed 150 °C.
Does JANS1N6123AUS/TR require external current limiting?
Yes, JANS1N6123AUS/TR must be used with a series current-limiting resistor to maintain operation within its 1.5 W power rating. At 12 V Zener voltage, the resistor must limit average current to ≤125 mA; transient surge handling depends on pulse duration and duty cycle per MIL-STD-750 Method 2074.
How does JANS1N6123AUS/TR differ from commercial 1N6123 diodes?
JANS1N6123AUS/TR differs from commercial 1N6123 variants in three key ways: it carries full MIL-PRF-19500/418 Class H qualification, uses hermetic glass packaging instead of plastic, and undergoes rigorous lot-level reliability screening including burn-in and thermal cycling - all absent in standard 1N6123 devices.
