Product details
Overview
JANTX1N4117D-1/TR from Microsemi is a 25 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 JANTX1N4117D-1/TR datasheet, JANTX1N4117D-1/TR pinout, JANTX1N4117D-1/TR application, or JANTX1N4117D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low dynamic impedance (150 Ω @ 250 mA), temperature coefficient (+0.090 %/°C), and radiation-hardened hermetic construction suitable for harsh-environment analog reference and overvoltage protection circuits.
Technical Context
This device operates as a precision shunt regulator with a nominal Zener voltage of 25.0 V at 250 mA test current (IZT), exhibiting a dynamic impedance of 150 Ω and reverse leakage current ≤0.01 µA at 19.0 V. Its metallurgical bond ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
The JANTX1N4117D-1/TR delivers low noise density (1 µV/√Hz typical at 25 V), minimal capacitance (~14 pF), and inherent radiation hardness per Microsemi MicroNote 050 - enabling use in low-noise analog references and space-grade power conditioning where parametric stability under thermal and radiation stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25.0 V ±1% at 250 mA - enables precise voltage clamping in regulated power rails requiring tight tolerance. |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in compact through-hole designs with linear derating to zero at 175 °C. |
| Dynamic Impedance (ZZT) | 150 Ω @ IZT = 250 mA - ensures stable output voltage under varying load currents in feedback and reference circuits. |
| Temp. Coefficient (αVZ) | +0.090 %/°C - provides predictable, monotonic drift for temperature-compensated reference designs. |
| Noise Density (ND) | 1 µV/√Hz - minimizes added noise in precision analog signal chains and low-noise voltage references. |
| Reverse Leakage (IR) | ≤0.01 µA @ VR = 19.0 V - guarantees low standby current in high-impedance bias and sensing networks. |
Pinout & Package
Hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by band; operated with banded end positive for Zener regulation. Leads are tin-lead plated and solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during forward conduction; grounded node in shunt regulation | Connected to system ground or low-impedance return path to establish reference potential. |
| Cathode | Regulated output node during reverse breakdown | Banded terminal connected to voltage rail being stabilized; carries full Zener current in regulation mode. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair. | Select when automated assembly and space-constrained layouts outweigh manual serviceability needs. |
| JAN1N4117D-1 | Identical Zener parameters and package, but qualified only to JAN level (lower screening rigor than JANTX). | Approved for commercial/military non-critical subsystems; not cleared for flight-critical avionics. | Choose for cost-sensitive programs where full JANTX screening is not mandated by system-level spec. |
Compared with JANTX1N4117D-1/TR, the 1N4117US-1 offers identical regulation performance in a smaller footprint but eliminates field-replaceability, while JAN1N4117D-1 reduces procurement cost and lead time at the expense of radiation and burn-in validation required for space-grade deployment.

FAQ
What is the Zener voltage tolerance of JANTX1N4117D-1/TR?
The JANTX1N4117D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This means its nominal 25.0 V Zener voltage is guaranteed between 24.75 V and 25.25 V at 250 mA test current and 25 °C ambient temperature, supporting high-accuracy reference design without post-manufacture trimming.
Is JANTX1N4117D-1/TR RoHS compliant?
No, JANTX1N4117D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for MIL-qualified JANTX-level devices like JANTX1N4117D-1/TR, which retain traditional tin-lead plating to meet military solderability and reliability standards.
What is the maximum junction temperature rating for JANTX1N4117D-1/TR?
The JANTX1N4117D-1/TR has a maximum junction and storage temperature rating of +175 °C, with a minimum of -65 °C. This wide range supports operation in extreme environments such as engine-mounted avionics or downhole oilfield electronics, provided thermal derating per Figure 2 in the datasheet is applied above 50 °C lead temperature.
How does the noise performance of JANTX1N4117D-1/TR compare to lower-voltage Zeners?
JANTX1N4117D-1/TR exhibits a typical noise density of 1 µV/√Hz - significantly lower than higher-voltage Zeners (e.g., 6.8 V parts show 40 µV/√Hz) due to reduced avalanche contribution. This makes JANTX1N4117D-1/TR especially suitable for low-noise analog references where spectral purity directly impacts measurement resolution.
Can JANTX1N4117D-1/TR be used in surface-mount designs?
No, JANTX1N4117D-1/TR uses an axial-leaded DO-35 (DO-204AH) glass package and is not compatible with surface-mount assembly. For SMT equivalents, consider Microsemi's 1N4117US-1 in DO-213AA package - same electrical specs but designed for reflow soldering and automated placement.
