Product details
Overview
JAN1N4106-1 from Microsemi is a 500 mW, 12.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JAN1N4106-1 datasheet, JAN1N4106-1 pinout, JAN1N4106-1 application, or JAN1N4106-1 equivalent, key selection criteria include its 12.0 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.05 µA maximum reverse leakage at 9.2 V, and +0.080 %/°C temperature coefficient - all critical for precision reference and overvoltage protection design.
Technical Context
This device operates as a two-terminal shunt voltage regulator with cathode-banded polarity, requiring reverse bias for Zener conduction. Its metallurgical bond construction ensures stable junction characteristics across -65 °C to +175 °C operating range and inherent radiation hardness per MicroNote 050.
It delivers 12.0 V regulation with 5% tolerance at IZT = 250 mA, exhibits 200 Ω dynamic impedance (ZZT) at that current, and maintains ≤0.05 µA reverse leakage (IR) at VR = 9.2 V - enabling stable reference generation under varying load and thermal conditions without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.0 V ±5% at 250 mA - defines precise regulation point for feedback loops and reference rails. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - sets maximum continuous thermal load on PCB layout. |
| Dynamic Impedance ZZT | 200 Ω max at 250 mA - determines output voltage variation under load transients. |
| Reverse Leakage IR | ≤0.05 µA at 9.2 V - ensures minimal quiescent current in standby or low-power monitoring circuits. |
| Temp. Coefficient αVZ | +0.080 %/°C - quantifies voltage drift per degree, critical for wide-temperature-range instrumentation. |
| Noise Density ND | 1 µV/√Hz (typical) - supports low-noise analog references where spectral purity matters. |
| Junction Temp. Range | -65 °C to +175 °C - enables operation in extreme environmental conditions without derating penalties. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node when used in shunt regulation configuration. |
| Cathode | Zener breakdown terminal / regulated output node | Banded end; connected to unregulated input rail; supplies stable 12.0 V to load or error amplifier input. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JAN qualification | Guarantees screening, testing, and traceability for defense/aerospace programs requiring Class S reliability. |
| Metallurgical bond construction | Ensures long-term parameter stability and resistance to thermal cycling-induced degradation. |
| Low noise density (1 µV/√Hz) | Enables use in precision analog references where broadband noise would corrupt ADC or op-amp inputs. |
| Hermetic glass sealing | Prevents moisture ingress and parametric shift in humid or corrosive environments over decades of service. |
| Radiation hardness (per MicroNote 050) | Supports deployment in space or nuclear systems without additional shielding or derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4106US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair. | Select when board space constraints or production line requirements mandate SMT packaging. |
| JANTX1N4106-1 | Identical electrical and mechanical specs; differs only in screening level (JANTX vs JAN). | JANTX includes extended burn-in and parametric testing beyond JAN baseline; required for higher-tier defense contracts. | Select when procurement specification mandates JANTX-level reliability screening. |
Compared with JAN1N4106-1, the 1N4106US-1 offers identical regulation performance in a compact SMT form factor, while JANTX1N4106-1 adds enhanced screening for mission-critical deployments - both preserve the 12.0 V ±5%, 200 Ω ZZT, and -65 °C to +175 °C operational envelope.

FAQ
What is the Zener voltage tolerance for JAN1N4106-1?
JAN1N4106-1 has a nominal Zener voltage of 12.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered electrical characteristics table. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Is JAN1N4106-1 RoHS compliant?
No, JAN1N4106-1 is not RoHS compliant. RoHS-compliant versions (e.g., with e3 suffix) are available only for commercial-grade variants; JAN-level parts retain tin-lead plating per MIL-STD-750 method 2026 to meet legacy military solderability and reliability standards.
What is the maximum reverse leakage current for JAN1N4106-1?
JAN1N4106-1 specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 9.2 V, measured at 25 °C. This ultra-low leakage supports low-power monitoring circuits and ensures minimal loading on high-impedance reference nodes.
Can JAN1N4106-1 be used in surface-mount designs?
JAN1N4106-1 itself is axial-leaded DO-35 packaged and not suitable for SMT. However, the functionally identical 1N4106US-1 variant uses the DO-213AA surface-mount package and shares identical electrical specifications including 12.0 V Zener voltage and 200 Ω dynamic impedance.
What is the temperature coefficient of JAN1N4106-1?
JAN1N4106-1 has a temperature coefficient (αVZ) of +0.080 %/°C, meaning its Zener voltage increases by approximately 9.6 mV per degree Celsius rise in junction temperature - a value confirmed in the Electrical Characteristics table and critical for thermal drift budgeting in precision analog systems.
