Product details
Overview
JANTX1N4111D-1/TR from Microsemi is a 17.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4111D-1/TR datasheet, JANTX1N4111D-1/TR pinout, JANTX1N4111D-1/TR application, or JANTX1N4111D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference and overvoltage protection design.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with Zener test current IZT = 250 mA and nominal Zener voltage VZ = 17.0 V at 25 °C. Its internal metallurgical bond ensures stable regulation across -65 °C to +175 °C junction temperature range.
It exhibits low dynamic impedance ZZT = 100 Ω at IZT, maximum reverse leakage IR = 0.05 µA at VR = 13.0 V, and noise density ND = 1 µV/√Hz - enabling use in low-noise analog references and precision biasing circuits where stability under thermal and current variation is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 17.0 V ±1% at IZT = 250 mA - provides tight reference accuracy for calibration-critical circuits. |
| Power Dissipation PM(AV) | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - defines safe operating envelope on standard PCB layouts. |
| Dynamic Impedance ZZT | 100 Ω at IZT = 250 mA - ensures minimal output voltage shift under load current variation. |
| Temperature Coefficient αVZ | +0.090 %/°C - enables predictable drift compensation in wide-temperature environments. |
| Noise Density ND | 1 µV/√Hz at IZT - supports ultra-low-noise reference applications such as instrumentation amplifiers and ADC biasing. |
| Reverse Leakage IR | 0.05 µA at VR = 13.0 V - guarantees negligible quiescent current draw in standby regulation modes. |
| Junction Temperature Range | -65 °C to +175 °C - meets extended environmental requirements for avionics and space-grade electronics. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode indicated by band; operated with banded end positive for Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or low-impedance return path; establishes reference node for regulated output. |
| Cathode | Zener regulation terminal / input for reverse bias | Connected to unregulated supply; voltage drop across diode stabilizes at VZ when reverse biased above breakdown threshold. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1 | Same VZ = 17.0 V, same 1% tolerance, but in surface-mount DO-213AA package; no axial leads. | Requires SMT assembly and reflow-compatible PCB layout; unsuitable for through-hole prototyping or high-vibration mechanical mounting. | Select when board space is constrained and automated assembly is used; verify thermal pad design for 500 mW dissipation. |
| JANTXV1N4111D-1 | Identical electrical specs but qualified to higher JANTXV reliability level per MIL-PRF-19500/435; tighter screening and lot traceability. | Required for programs demanding enhanced burn-in, radiation testing, and failure analysis reporting (e.g., NASA Class S). | Choose when program specifications mandate JANTXV or higher; otherwise JANTX1N4111D-1 meets standard high-reliability needs. |
Compared with JANTX1N4111D-1/TR, the 1N4111US-1 offers footprint reduction at the cost of mechanical robustness and hand-soldering compatibility, while JANTXV1N4111D-1 adds qualification rigor without altering electrical behavior - making the original optimal for balanced performance, reliability, and manufacturability.

FAQ
What is the Zener voltage tolerance of JANTX1N4111D-1/TR?
JANTX1N4111D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This means its nominal 17.0 V Zener voltage is guaranteed between 16.83 V and 17.17 V at IZT = 250 mA and 25 °C, supporting high-accuracy reference applications without external trimming.
Is JANTX1N4111D-1/TR RoHS compliant?
No, JANTX1N4111D-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTX-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum reverse leakage current for JANTX1N4111D-1/TR?
The maximum reverse leakage current IR for JANTX1N4111D-1/TR is 0.05 µA at VR = 13.0 V and 25 °C. This ultra-low leakage ensures minimal power loss in standby regulation and preserves accuracy in high-impedance bias networks where leakage could cause offset errors.
Can JANTX1N4111D-1/TR be used in surface-mount designs?
No, JANTX1N4111D-1/TR uses a DO-35 axial-leaded glass package and is intended for through-hole mounting. For surface-mount equivalents, consider the 1N4111US-1 in DO-213AA package - but note it lacks JANTX qualification and requires SMT process validation.
What is the temperature coefficient of JANTX1N4111D-1/TR?
The temperature coefficient αVZ of JANTX1N4111D-1/TR is +0.090 %/°C. This positive coefficient indicates that its Zener voltage increases predictably with rising temperature, enabling straightforward drift compensation in wide-temperature-range designs such as avionics power supplies.
