Product details
Overview
JANTXV1N4109D-1 from Microsemi is a 15.0 V, 1% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supply circuits.
For engineers reviewing the JANTXV1N4109D-1 datasheet, JANTXV1N4109D-1 pinout, JANTXV1N4109D-1 application, or JANTXV1N4109D-1 equivalent, key selection criteria include its 15.0 V nominal Zener voltage at 250 mA test current, 100 Ω dynamic impedance, 40 µA maximum reverse leakage at 12.0 V, and +0.085 %/°C temperature coefficient - critical for precision reference and biasing in harsh-environment analog systems.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with metallurgical bonding ensuring stable junction characteristics under thermal cycling and radiation exposure. Its low noise density (1 µV/√Hz typical at 15 V) and minimal capacitance support use in low-noise reference paths.
The JANTXV qualification mandates rigorous screening including burn-in, temperature cycling, and hermeticity testing. It exhibits linear power derating from 500 mW at 25 °C to zero at 175 °C ambient, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4109US | Same 15.0 V, 1% spec, but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; no axial-lead compatibility | Select for space-constrained boards where through-hole mounting is impractical |
| 1N4109UR-1 | Commercial-grade (non-mil), same 15.0 V/1%, DO-35 package | Lacks JANTXV screening; not rated for -65 °C or radiation environments | Select for cost-sensitive industrial prototypes where full mil-spec is unnecessary |
Compared with JANTXV1N4109D-1, JANTXV1N4109US offers identical electrical performance in a surface-mount form factor, while 1N4109UR-1 provides functional equivalence at lower cost and screening level - both require explicit validation for target environmental and reliability requirements.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4109D-1?
JANTXV1N4109D-1 has a nominal Zener voltage of 15.0 V with a tolerance of ±1%, measured at 250 mA test current and 25 °C. This tight tolerance is achieved via post-process sorting and is maintained across its qualified operating temperature range of -65 to +175 °C junction temperature.
What does the "D" suffix mean in JANTXV1N4109D-1?
The "D" suffix in JANTXV1N4109D-1 indicates 1% Zener voltage tolerance per the Microsemi part nomenclature. In the JEDEC-based naming convention, "D" corresponds to ±1%, "C" to ±2%, and blank to ±5%. This designation is confirmed in the T4-LDS-0245-2 datasheet revision 1.
Is JANTXV1N4109D-1 RoHS compliant?
No, JANTXV1N4109D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only on commercial-grade parts, not on JANTXV-qualified devices. JANTXV1N4109D-1 uses traditional tin-lead plating per MIL-STD-750 Method 2026.
What is the maximum reverse leakage current for JANTXV1N4109D-1?
JANTXV1N4109D-1 has a maximum reverse leakage current (IR) of 0.05 µA at 12.0 V reverse voltage and 25 °C. This ultra-low leakage supports high-impedance bias networks and minimizes power loss in battery-backed or low-power systems.
How is JANTXV1N4109D-1 packaged and marked?
JANTXV1N4109D-1 is supplied in the DO-35 (DO-204AH) axial-leaded glass package with cathode identified by a color band. The device is marked with its full part number "JANTXV1N4109D-1", and weighs approximately 0.2 grams. Lead finish is tin-lead per MIL-STD-750.
