Product details
Overview
JANTX1N4106-1 from Microsemi is a 500 mW, 12.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JANTX1N4106-1 datasheet, JANTX1N4106-1 pinout, JANTX1N4106-1 application, or JANTX1N4106-1 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 -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 12.0 V at IZT = 250 mA and exhibits a positive temperature coefficient of +0.080 %/°C. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The diode delivers low-noise regulation with 1 µV/√Hz noise density at 12 V and maintains ≤200 Ω dynamic impedance across its rated current range. It is designed for operation with cathode band positive relative to anode, requiring correct polarity mounting in series-shunt configurations.
Key Specifications

| Zener Test Current | 250 mA - establishes stable regulation point and thermal operating point |
| Max Dynamic Impedance | 200 Ω - limits output voltage variation under load current changes |
| Max Reverse Leakage | 0.05 µA at 9.2 V - ensures minimal standby power loss in high-impedance bias networks |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous DC power handling before derating begins |
| Temp Coefficient αVZ | +0.080 %/°C - quantifies voltage drift per degree Celsius for precision reference design |
| Junction Temp Range | -65 °C to +175 °C - supports operation in extreme environmental conditions without parameter shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4106US | Same 12.0 V Zener voltage, but in surface-mount DO-213AA package; no MIL qualification | Lacks JANTX screening and radiation tolerance; suitable only for commercial industrial designs | Select when board space is constrained and military-grade reliability is not required |
| JAN1N4106-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less rigorous screening than JANTX) | Lower cost and shorter lead time, but not approved for mission-critical flight hardware | Select when full JANTX qualification is unnecessary and budget or schedule constraints dominate |
Compared with JANTX1N4106-1, 1N4106US offers footprint reduction but sacrifices hermeticity and radiation hardness, while JAN1N4106-1 retains the same package and voltage but omits JANTX-level burn-in and parametric screening-making it viable for less demanding high-reliability systems.

The JANTX1N4106-1 belongs to Microsemi's legacy 1N4099–1N4135 family of MIL-qualified Zener diodes, engineered specifically for voltage regulation in mission-critical systems where stability, radiation tolerance, and long-term parametric consistency are mandatory.
FAQ
What is the Zener voltage tolerance for JANTX1N4106-1?
JANTX1N4106-1 has a nominal Zener voltage of 12.0 V with a standard tolerance of ±5%, as defined in the JEDEC specification and confirmed in Microsemi's T4-LDS-0245-2 datasheet. This tolerance applies under standard test conditions at 25 °C with IZT = 250 mA. No tighter tolerance (e.g., 2% or 1%) is offered for this specific JANTX-qualified variant.
Does JANTX1N4106-1 require heatsinking in typical applications?
JANTX1N4106-1 does not require external heatsinking when operated at or below its 500 mW rated power dissipation at 25 °C ambient, provided leads are trimmed to 3/8 inch (10 mm) from body per datasheet RθJL = 250 °C/W. At higher ambient temperatures, linear derating begins at 50 °C and reaches zero at 175 °C-so heatsinking may be needed only in high-power or high-temperature enclosures.
Is JANTX1N4106-1 RoHS compliant?
No, JANTX1N4106-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS qualified parts. The JANTX1N4106-1 uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum reverse leakage current for JANTX1N4106-1?
The maximum reverse leakage current for JANTX1N4106-1 is 0.05 µA at VR = 9.2 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value is measured at 25 °C and reflects the device's ability to maintain high-impedance blocking behavior well below its Zener knee.
Can JANTX1N4106-1 be used in surface-mount designs?
No, JANTX1N4106-1 is packaged exclusively in the axial-leaded DO-35 (DO-204AH) through-hole format. For surface-mount equivalents, Microsemi offers the 1N4106US in DO-213AA package-but that part lacks JANTX qualification, hermetic glass construction, and radiation hardness. JANTX1N4106-1 requires through-hole PCB assembly.
