Product details
Overview
JANTX1N4116D-1 from Microsemi is a 500 mW, 24.0 V ±1% tolerance 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 JANTX1N4116D-1 datasheet, JANTX1N4116D-1 pinout, JANTX1N4116D-1 application, or JANTX1N4116D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and hermetic DO-35 packaging for stable operation across -65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 24.0 V at 250 mA test current (IZT), exhibiting dynamic impedance of 150 Ω at IZT and reverse leakage current ≤0.01 µA at 18.3 V (VR). Its metallurgical bond construction ensures low noise and radiation hardness per MicroNote 050.
The JANTX1N4116D-1 delivers stable regulation over wide current (1–40 mA operating range) and temperature (-65 °C to +175 °C junction), with thermal resistance junction-to-lead of 250 °C/W and linear power derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24.0 V ±1% at 250 mA - enables precise reference generation in analog circuits requiring tight voltage stability |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in compact, unheatsinked designs with linear derating above 50 °C |
| Zener Impedance (ZZT) | 150 Ω at 250 mA - ensures minimal output voltage variation under load transients in feedback loops |
| Noise Density (ND) | 1 µV/√Hz - critical for low-noise references in precision instrumentation and ADC biasing |
| Temp Coefficient (αVZ) | +0.090 %/°C - predictable positive drift simplifies temperature compensation in wide-range environments |
| Reverse Leakage (IR) | ≤0.01 µA at 18.3 V - guarantees negligible standby current in battery-backed or ultra-low-power systems |
| Junction Temp Range | -65 °C to +175 °C - validated for operation in extreme aerospace, downhole, and military platforms |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-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 wire-wrap | Select when automated assembly and board space constraints outweigh manual handling needs |
| JAN1N4116D-1 | Identical electrical and mechanical specs; differs only in qualification level (JAN vs JANTX) | JAN level lacks extended life test data required for Class H avionics; JANTX adds burn-in and lot acceptance testing | Choose JANTX1N4116D-1 for programs requiring MIL-PRF-19500/435 Clause 3.5.2 compliance |
Compared with 1N4116US-1 and JAN1N4116D-1, the JANTX1N4116D-1 uniquely balances full JANTX qualification, axial-leaded DO-35 form factor, and ±1% tolerance-making it the default choice for legacy-replacement and high-assurance through-hole designs.

FAQ
What is the Zener voltage tolerance of JANTX1N4116D-1?
JANTX1N4116D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per MIL-PRF-19500/435 nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where VZ = 24.0 V at IZT = 250 mA with ZZT = 150 Ω and IR ≤ 0.01 µA at VR = 18.3 V. The tighter tolerance reduces calibration overhead in precision reference designs.
Is JANTX1N4116D-1 RoHS compliant?
No, JANTX1N4116D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4116D-1. The JANTX1N4116D-1 uses tin-lead plating per MIL-STD-750 method 2026, which is exempt from RoHS under Annex III.
What is the maximum operating temperature for JANTX1N4116D-1?
JANTX1N4116D-1 has a junction and storage temperature range of -65 °C to +175 °C, as specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2. Its thermal resistance junction-to-lead is 250 °C/W, and power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C-enabling reliable operation in engine bay, downhole, and spacecraft thermal environments.
How does the noise performance of JANTX1N4116D-1 compare to lower-voltage Zeners?
JANTX1N4116D-1 exhibits a noise density of 1 µV/√Hz, consistent with the datasheet's statement that noise falls quickly to this value at lower Zener voltages. In contrast, 6.8 V and higher Zeners in the same family show up to 40 µV/√Hz. This ultra-low noise makes JANTX1N4116D-1 especially suitable for precision analog front-ends where signal integrity is critical.
Can JANTX1N4116D-1 be used in surface-mount designs?
No, JANTX1N4116D-1 is packaged exclusively in the axial-leaded DO-35 (DO-204AH) glass case. For surface-mount equivalents, Microsemi offers the 1N4116US-1 in DO-213AA package-but that part carries different qualification (commercial or JAN, not JANTX) and lacks the same mil-spec traceability. JANTX1N4116D-1 requires through-hole mounting.
