Product details
Overview
JANS1N4106C-1/TR from Microsemi is a 12 V, 2% 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 JANS1N4106C-1/TR datasheet, JANS1N4106C-1/TR pinout, JANS1N4106C-1/TR application, or JANS1N4106C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), radiation hardness, hermetic DO-35 packaging, MIL-qualified reliability level, and thermal derating behavior above 50 °C.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band indicating polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, critical for space-grade deployments.
The JANS1N4106C-1/TR exhibits a positive temperature coefficient of +0.080 %/°C and maintains ≤0.05 µA reverse leakage at 9.2 V, enabling stable reference generation in analog power supply feedback loops and voltage-clamping circuits where long-term parametric drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.0 V ±2% at 250 mA - provides tight reference accuracy for regulated power rails and precision biasing. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to system ground or common return; forms low-impedance path for Zener current sink. |
| Cathode (banded end) | Regulated output node | Supplies stable 12 V reference; must be decoupled locally to suppress noise coupling into sensitive analog circuitry. |

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 12 V, 2% spec but in DO-213AA surface-mount package; no axial leads; slightly higher RθJL (300 °C/W). | Used where board space is constrained and wave-soldering is not required; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when automated SMT assembly is mandatory and thermal interface to PCB copper is optimized. |
| JANTXV1N4106C-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS); lower screening rigor, no radiation hardness validation. | Approved for airborne non-space platforms (e.g., radar EW pods) where TID tolerance is not mandated but extended temperature operation is required. | Select for cost-sensitive defense programs where full JANS qualification adds unnecessary overhead. |
Compared with 1N4106US-1 and JANTXV1N4106C-1, the JANS1N4106C-1/TR uniquely combines hermetic axial packaging, full JANS screening, and radiation hardness-making it the sole option for space-qualified voltage reference designs demanding zero parametric drift over mission lifetime.

FAQ
What is the Zener voltage tolerance and test current for JANS1N4106C-1/TR?
JANS1N4106C-1/TR has a nominal Zener voltage of 12.0 V with ±2% tolerance, measured at a Zener test current (IZT) of 250 mA. This tolerance is achieved via post-process binning and is guaranteed across the full qualified temperature range per MIL-PRF-19500/435 requirements.
Is JANS1N4106C-1/TR radiation-hardened, and what is the evidence?
Yes, JANS1N4106C-1/TR is inherently radiation-hardened as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide immunity to total ionizing dose (TID) effects up to 100 krad(Si), confirmed through lot-specific radiation testing per MIL-STD-883 Method 1019.
What is the maximum reverse leakage current specification for JANS1N4106C-1/TR?
JANS1N4106C-1/TR specifies a maximum reverse leakage current (IR) of 0.05 µA at 9.2 V (0.77 × VZ). This ultra-low leakage ensures minimal error contribution in high-impedance reference divider networks and preserves accuracy in battery-powered remote sensors.
Does JANS1N4106C-1/TR require derating above ambient temperature, and if so, how?
Yes, JANS1N4106C-1/TR must be linearly derated starting at 50 °C lead temperature, reaching zero power dissipation at 175 °C. On a typical FR4 board with 4 mm² copper pads, it derates from 500 mW at 25 °C ambient, following the curve in Figure 2 of T4-LDS-0245-2 Rev. 1.
What does the "TR" suffix signify in JANS1N4106C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. The base part JANS1N4106C-1 is identical electrically and mechanically; only the packaging format differs-bulk vs. reel-supporting high-volume manufacturing workflows.
