Product details
Overview
JANTX1N4109C-1/TR from Microsemi is a 15 V, 2% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, metallurgically bonded for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4109C-1/TR datasheet, JANTX1N4109C-1/TR pinout, JANTX1N4109C-1/TR application, or JANTX1N4109C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and MIL-PRF-19500/435 qualification details required for precision analog reference and overvoltage protection design.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 15.0 V at 250 mA test current, ±2% tolerance (denoted by "C"), and +0.080 %/°C temperature coefficient - optimized for stable regulation across -65 °C to +175 °C junction temperature range.
Its 100 Ω maximum dynamic impedance at IZT and 40 µV/√Hz noise density (typical for ≥6.8 V devices) support low-noise analog references; hermetic DO-35 glass construction ensures radiation hardness and ESD immunity per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 15.0 V at 250 mA - defines precise regulation point for feedback loops and reference rails. |
| Zener Tolerance | ±2% - tighter than standard ±5%, enabling higher accuracy in precision voltage monitoring. |
| Power Dissipation | 500 mW - supports robust operation in discrete regulator stages without forced cooling. |
| Dynamic Impedance ZZT | ≤200 Ω - ensures minimal output voltage shift under load transients in feedback networks. |
| Temperature Coefficient αVZ | +0.080 %/°C - predictable positive drift allows compensation in wide-temperature designs. |
| Noise Density ND | ≤40 µV/√Hz - low broadband noise critical for sensor excitation and ADC reference stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4109US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and reflow compatibility is mandatory. |
| JANS1N4109C-1 | Identical electrical and mechanical specs, but qualified to JANS (space-level) per MIL-PRF-19500/435. | Necessary for Class S spaceflight hardware; requires additional screening and traceability documentation. | Select only when full JANS certification and lot traceability are contractually required. |
Compared with JANTX1N4109C-1/TR, the DO-213AA alternative enables PCB miniaturization but sacrifices mechanical robustness, while the JANS variant adds cost and lead time solely for enhanced screening - neither offers improved electrical performance.

FAQ
What is the Zener voltage and tolerance of JANTX1N4109C-1/TR?
JANTX1N4109C-1/TR has a nominal Zener voltage of 15.0 V at 250 mA test current with ±2% tolerance, as indicated by the "C" suffix in its part number. This tight tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet and applies across the full operating temperature range when used within derated power limits.
Is JANTX1N4109C-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTX1N4109C-1/TR is qualified to MIL-PRF-19500/435 at the JANTX reliability level, as explicitly stated in the "Qualified Levels" section on page 1 of the datasheet. This includes screening for temperature cycling, steady-state life, and hermeticity - making it suitable for high-integrity defense systems.
What package type does JANTX1N4109C-1/TR use?
JANTX1N4109C-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Its mechanical dimensions, including body diameter (BD), body length (BL), and lead specifications, are fully detailed on page 5 of the Microsemi T4-LDS-0245-2 datasheet.
What is the maximum power dissipation and derating behavior of JANTX1N4109C-1/TR?
JANTX1N4109C-1/TR has a rated average power dissipation of 500 mW at 25 °C lead temperature. Per Figure 2 in the datasheet, it linearly derates to zero at 175 °C - meaning usable power drops to ~375 mW at 50 °C lead temperature and follows a straight-line reduction thereafter.
Does JANTX1N4109C-1/TR have low noise characteristics suitable for precision references?
Yes, JANTX1N4109C-1/TR exhibits ≤40 µV/√Hz noise density at its 15 V Zener voltage, consistent with Microsemi's specification for devices ≥6.8 V. This low broadband noise is validated in Figure 1 and supports use in high-resolution ADC references and low-drift analog circuits.
