Product details
Overview
JANTXV1N4108C-1 from Microsemi is a 500 mW, 14.0 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance at 25 °C - used for precision voltage reference and regulation in military-grade power supply monitoring circuits.
For engineers reviewing the JANTXV1N4108C-1 datasheet, JANTXV1N4108C-1 pinout, JANTXV1N4108C-1 application, or JANTXV1N4108C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), hermetic glass packaging, MIL-qualified thermal stability (–65 to +175 °C), and metallurgical bond construction for high-reliability analog reference design.
Technical Context
This device operates as a reverse-biased Zener regulator with a nominal breakdown voltage of 14.0 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.085 %/°C and dynamic impedance of 200 Ω. Its metallurgically bonded junction ensures stable regulation across wide current (10.7–40 mA IZM range) and temperature extremes.
Designed for high-reliability analog reference applications, it delivers low noise density (1 µV/√Hz), minimal capacitance (typ. <2 pF), and ESD insensitivity per MIL-STD-750 Method 1020 - all within a hermetically sealed DO-35 (DO-204AH) glass package rated for 500 mW average power dissipation.
Key Specifications

Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package: hermetically sealed, cathode indicated by band; banded end is anode when operated in forward bias, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward conduction terminal / Zener regulation return path | Connected to circuit ground or lower-potential node during regulation; carries full Zener current |
| Cathode (banded end) | Zener regulation output terminal | Provides stable 14.0 V reference relative to anode; must be held at higher potential than anode for breakdown operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4108US-1 | Same 14.0 V ±2% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated SMT production and board space savings outweigh lead-forming flexibility |
| JANTXV1N4108D-1 | Identical electrical specs except ±1% Zener tolerance (D suffix); otherwise identical construction and qualification | Used where tighter initial voltage accuracy is required for uncalibrated reference chains | Select when system-level calibration is impractical and ±1% absolute accuracy is mandated |
Compared with JANTXV1N4108C-1, the JANTXV1N4108D-1 offers improved initial accuracy at higher cost and same reliability, while the 1N4108US-1 trades axial-leaded serviceability for SMT manufacturability - neither is pin-compatible due to differing packages.

FAQ
What is the Zener voltage tolerance of JANTXV1N4108C-1?
JANTXV1N4108C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its measured VZ at 250 mA falls between 13.72 V and 14.28 V at 25 °C. The tolerance is guaranteed under MIL-PRF-19500/435 JANTXV screening, and applies across the full qualified temperature range when used within specified power limits.
Is JANTXV1N4108C-1 RoHS compliant?
No, JANTXV1N4108C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants (blank reliability level), not for JAN, JANTX, JANTXV, or JANS qualified parts. JANTXV1N4108C-1 retains traditional tin-lead plating to meet MIL-STD-750 solderability requirements and ensure long-term reliability in high-reliability applications.
What is the maximum Zener current IZM for JANTXV1N4108C-1?
The maximum Zener current IZM for JANTXV1N4108C-1 is 40 mA, derived from its 500 mW power rating and 14.0 V nominal Zener voltage (P = V × I → I = 0.5 W / 14 V ≈ 35.7 mA, rounded to 40 mA per datasheet Table on Page 3). This value assumes operation at 25 °C; derating is required above 50 °C per the published power curve.
Does JANTXV1N4108C-1 have radiation hardness specifications?
Yes, JANTXV1N4108C-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded glass package and silicon structure provide tolerance to total ionizing dose (TID) and single-event effects (SEE) relevant to space and nuclear environments. While no specific TID or LET values are listed in the T4-LDS-0245-2 datasheet, the JANTXV qualification level implies screening to MIL-PRF-19500/435 radiation test requirements.
What is the thermal resistance junction-to-lead (RθJL) for JANTXV1N4108C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4108C-1 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the package body. This value enables thermal modeling of power dissipation in lead-mounted configurations, such as chassis-mounted or socketed implementations where heat is conducted primarily through the leads rather than ambient air.
