Product details
Overview
JANS1N4106-1/TR from Microsemi is a 500 mW, 12.0 V Zener voltage regulator diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±5% Zener tolerance, 9.2 mA maximum Zener current at 25 °C, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4106-1/TR datasheet, JANS1N4106-1/TR pinout, JANS1N4106-1/TR application, or JANS1N4106-1/TR equivalent, key selection criteria include its military-grade qualification, low noise density (1 µV/√Hz), stable temperature coefficient (+0.080 %/°C), and metallurgically bonded construction for radiation hardness and thermal reliability.
Technical Context
This axial-leaded Zener diode operates in reverse breakdown to maintain precise DC reference voltage under varying load and temperature conditions. Its internal metallurgical bond ensures mechanical robustness and low thermal resistance (RθJL = 250 °C/W), critical for sustained operation at elevated ambient temperatures.
The device exhibits a dynamic impedance of 200 Ω at 250 mA test current and maintains ≤0.05 µA reverse leakage at 9.2 V, enabling stable regulation in low-power analog references and precision bias networks where low drift and minimal capacitance (<2 pF typical) are required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4106-1 | Same electrical specs but qualified only to JANTXV level; lacks full JANS screening (e.g., burn-in, radiation testing) | Suitable for high-reliability ground-based systems where full space qualification is not mandated | Select when cost sensitivity outweighs requirement for full JANS radiation hardness and lot traceability |
| 1N4106US-TR | Commercial-grade DO-213AA surface-mount variant; same VZ, but RθJA = 400 °C/W and no military qualification | Used in non-military industrial controls where automated assembly and board space are prioritized over environmental ruggedness | Select only for commercial applications with no radiation, shock, or extended temperature requirements |
Compared with JANS1N4106-1/TR, JANTXV1N4106-1 offers reduced screening rigor and lower cost while retaining identical Zener characteristics, whereas 1N4106US-TR trades military reliability for SMT compatibility and RoHS compliance-neither is a drop-in replacement for JANS-level deployment.

FAQ
What is the Zener voltage tolerance for JANS1N4106-1/TR?
JANS1N4106-1/TR has a nominal Zener voltage of 12.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with 250 mA test current.
Is JANS1N4106-1/TR suitable for space applications?
Yes, JANS1N4106-1/TR is qualified to JANS level per MIL-PRF-19500/435, including radiation hardness per Microsemi MicroNote 050, full lot traceability, and extended temperature screening from –65 °C to +175 °C-making it suitable for low-earth orbit and deep-space missions where single-event effects and TID resilience are critical.
What is the maximum Zener current rating for JANS1N4106-1/TR?
The maximum Zener current IZM for JANS1N4106-1/TR is 9.2 mA at 25 °C, derived from its 500 mW power rating and 12.0 V Zener voltage. This value is linearly derated above 50 °C ambient per the power derating curve in Figure 2 of the datasheet.
Does JANS1N4106-1/TR have RoHS compliance?
No, JANS1N4106-1/TR is not RoHS compliant. Per the nomenclature guide on page 2, the "e3" suffix denotes RoHS compliance and is available only on commercial-grade versions (e.g., 1N4106-1e3). JANS-level parts retain tin-lead plating to meet MIL-STD-750 solderability requirements and do not carry the e3 designation.
What is the noise performance of JANS1N4106-1/TR?
JANS1N4106-1/TR has a maximum noise density of 1 µV/√Hz at 25 °C, measured using a 1 kHz–3 kHz bandpass filter and 250 mA Zener test current. This low noise enables use in precision analog references where spectral purity directly impacts measurement resolution.
