For engineers reviewing the JANTXV1N4108C-1/TR datasheet, JANTXV1N4108C-1/TR pinout, JANTXV1N4108C-1/TR application, or JANTXV1N4108C-1/TR equivalent, key selection factors include its 14.0 V nominal Zener voltage at 250 mA test current, 200 Ω dynamic impedance, 0.05 µA maximum reverse leakage at 10.7 V, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK and stable regulation over broad current (250 mA IZT) and temperature (-65 °C to +175 °C) ranges. Its internal metallurgical bond ensures mechanical robustness and low noise density (1 µV/√Hz typical at lower voltages).
The JANTXV1N4108C-1/TR exhibits a positive temperature coefficient of +0.085 %/°C and is rated for 0.5 W average power dissipation with linear derating above 50 °C lead temperature, making it suitable for stable reference generation in analog signal chains and regulated bias networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4108US-1TR | Same 14.0 V, ±2%, DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated placement is available |
| JANS1N4108C-1 | Identical electrical specs but qualified to JANS (highest MIL-PRF-19500 level); higher screening cost and longer lead time | Required only for Class-S spaceflight hardware; overqualified for ground-based military platforms | Select only when JANS-level radiation hardness and burn-in are mandated by program spec |
Compared with JANTXV1N4108C-1/TR, the 1N4108US-1TR offers identical regulation performance in a smaller footprint but sacrifices mechanical ruggedness and hand-soldering flexibility, while JANS1N4108C-1 adds radiation tolerance and extended screening at significantly higher cost and procurement latency.

FAQ
What is the nominal Zener voltage and test current for JANTXV1N4108C-1/TR?
The JANTXV1N4108C-1/TR has a nominal Zener voltage of 14.0 V measured at a Zener test current (IZT) of 250 mA. This value is specified under thermal equilibrium conditions at 25 °C ambient temperature and defines the primary regulation point for circuit design and tolerance analysis in the JANTXV1N4108C-1/TR application.
How does the ±2% tolerance of JANTXV1N4108C-1/TR impact its use in precision reference circuits?
The ±2% Zener voltage tolerance of JANTXV1N4108C-1/TR provides tighter regulation accuracy than standard 5% parts, reducing initial calibration burden in feedback networks. When combined with its +0.085 %/°C temperature coefficient and JANTXV screening, the JANTXV1N4108C-1/TR delivers predictable drift behavior, enabling stable reference performance across wide temperature ranges without active compensation.
Is JANTXV1N4108C-1/TR RoHS compliant?
No, JANTXV1N4108C-1/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (suffix e3) are available only on commercial-grade parts, not on JANTXV-qualified devices like JANTXV1N4108C-1/TR. The JANTXV1N4108C-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements for high-reliability applications.
What is the maximum reverse leakage current specification for JANTXV1N4108C-1/TR?
The JANTXV1N4108C-1/TR has a maximum reverse leakage current (IR) of 0.05 µA at a reverse voltage (VR) of 10.7 V. This ultra-low leakage ensures minimal error current in high-impedance reference nodes and preserves accuracy in precision analog circuits where input bias currents must be tightly controlled.
Can JANTXV1N4108C-1/TR be used in surface-mount designs?
No, JANTXV1N4108C-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT-compatible alternatives with identical electrical specs, consider the 1N4108US-1TR in DO-213AA package - but note that this part lacks JANTXV qualification and requires layout revision to accommodate its different footprint and mounting method.
