Product details
Overview
JANS1N4106D-1/TR from Microsemi is a 12 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, low noise density (1 µV/√Hz), and operates across –65 °C to +175 °C junction temperature.
For engineers reviewing the JANS1N4106D-1/TR datasheet, JANS1N4106D-1/TR pinout, JANS1N4106D-1/TR application, or JANS1N4106D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), radiation hardness, hermetic DO-35 packaging, MIL-qualified reliability level, and thermal derating behavior from 500 mW at 25 °C to zero at 175 °C.
Technical Context
This device functions as a precision shunt voltage regulator in feedback loops and reference circuits where long-term stability under extreme environmental stress is required. Its internal metallurgical bond ensures mechanical robustness and low parameter drift, while its 1% voltage tolerance and +0.080 %/°C temperature coefficient enable predictable performance across wide temperature excursions.
The JANS1N4106D-1/TR exhibits minimal capacitance (typical <2 pF at 12 V), supports low-noise analog references due to 1 µV/√Hz noise density at IZT, and maintains ≤0.05 µA reverse leakage at 9.2 V - critical for low-power biasing and sensing in radiation-hardened systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4106D-1 | Same 12 V ±1%, DO-35, but qualified only to JANTXV level (not JANS); no Class S screening. | Lacks full space-level burn-in and radiation testing; unsuitable for flight-critical avionics. | Select when cost sensitivity outweighs requirement for Class S qualification and extended radiation assurance. |
| 1N4106UR-1 | Same electrical specs, but in DO-213AA surface-mount package; RoHS-compliant plating. | Enables automated assembly and higher board density; not hermetically sealed like DO-35. | Select for commercial or industrial systems requiring SMT compatibility and no hermeticity mandate. |
Compared with JANS1N4106D-1/TR, JANTXV1N4106D-1 offers identical regulation performance but reduced reliability screening, while 1N4106UR-1 trades hermetic axial packaging for SMT manufacturability - choice depends on qualification depth and assembly method requirements.

FAQ
What is the Zener voltage and tolerance of JANS1N4106D-1/TR?
JANS1N4106D-1/TR has a nominal Zener voltage of 12.0 V with a tight ±1% tolerance at 250 mA test current, as specified in the Microsemi T4-LDS-0245-2 datasheet. This tolerance is achieved through precision sorting and is maintained across the full –65 °C to +175 °C junction temperature range, making JANS1N4106D-1/TR suitable for high-accuracy reference applications in harsh environments.
Is JANS1N4106D-1/TR qualified to JANS level per MIL-PRF-19500/435?
Yes, JANS1N4106D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including Class S (space) screening requirements such as extended burn-in, radiation testing, and lot traceability. The "JANS" prefix in the part number explicitly denotes this highest military reliability level, distinguishing it from JAN, JANTX, or JANTXV variants of the same base device.
What package type does JANS1N4106D-1/TR use, and what are its key mechanical features?
JANS1N4106D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with tin-lead plating. Key mechanical features include a 0.2 g mass, 25.4–38.1 mm lead length, cathode band marking, and compliance with MIL-STD-750 solderability testing. Its hermetic seal ensures long-term stability in high-humidity and corrosive environments typical of aerospace and marine deployments.
What is the maximum reverse leakage current for JANS1N4106D-1/TR, and at what voltage is it specified?
JANS1N4106D-1/TR has a maximum reverse leakage current (IR) of 0.05 µA, specified at a reverse voltage (VR) of 9.2 V - which is 77% of its 12 V Zener voltage. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision voltage divider circuits used in telemetry and sensor signal conditioning.
How does the temperature coefficient of JANS1N4106D-1/TR affect its voltage regulation stability?
JANS1N4106D-1/TR has a temperature coefficient (αVZ) of +0.080 %/°C, meaning its Zener voltage increases by approximately 9.6 mV per 10 °C rise above 25 °C. This predictable positive drift allows system designers to compensate in firmware or analog circuitry, and contributes to JANS1N4106D-1/TR's suitability for applications requiring stable references across wide operational temperature ranges, such as missile guidance electronics.
