Product details
Overview
JANTX1N4113D-1 from Microsemi is a 19.0 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 JANTX1N4113D-1 datasheet, JANTX1N4113D-1 pinout, JANTX1N4113D-1 application, or JANTX1N4113D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference design, radiation-hardened systems, and regulated bias generation under thermal stress.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 19.0 V at 250 mA test current, exhibiting +0.090 %/°C temperature coefficient and 150 Ω dynamic impedance (ZZT) at IZT. Its metallurgical bond ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
Designed for high-reliability analog circuits, JANTX1N4113D-1 delivers low noise density (1 µV/√Hz), minimal capacitance (~2.5 pF), and ESD insensitivity per MIL-STD-750 Method 1020 - enabling use in low-noise instrumentation references and hardened voltage monitors where parametric drift and transient immunity are mission-critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 19.0 V ±1% at 250 mA - provides precise, tightly controlled reference voltage for calibration and feedback loops. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports stable operation in conduction-cooled avionics enclosures. |
| Dynamic Impedance ZZT | 150 Ω at 250 mA - ensures minimal output voltage variation under load current transients in regulator shunt paths. |
| Temperature Coefficient αVZ | +0.090 %/°C - enables predictable voltage drift compensation in wide-temperature-range sensor signal conditioning. |
| Noise Density ND | 1 µV/√Hz - critical for ultra-low-noise reference applications such as precision ADC biasing and metrology front-ends. |
| Reverse Leakage IR | 50 nA max at 14.5 V - guarantees negligible current draw in high-impedance reference divider networks. |
| Junction Temp Range | -65 °C to +175 °C - validated for operation in space-grade and engine-mounted electronics without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4113US-1 | Same 19.0 V, 1% Zener voltage but in DO-213AA surface-mount package; no axial leads. | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or lead-forming requirements. | Select when automated assembly, board space constraints, or vibration resistance outweigh axial mounting flexibility. |
| JAN1N4113D | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX). | Lacks JANTX-level burn-in and life test data; not approved for Class H or Class K flight hardware. | Select only for non-flight-critical ground support equipment where cost reduction is prioritized over full JANTX screening. |
Compared with JANTX1N4113D-1, 1N4113US-1 trades axial-mount versatility for SMT compatibility, while JAN1N4113D reduces qualification rigor to lower unit cost - neither offers pin-compatible replacement without verifying mechanical fit and screening compliance for the target program.

FAQ
What is the Zener voltage tolerance of JANTX1N4113D-1?
JANTX1N4113D-1 has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its part number. This tight tolerance ensures the device maintains 19.0 V regulation within ±0.19 V at 250 mA test current and 25 °C, supporting high-accuracy reference designs without external trimming.
Is JANTX1N4113D-1 qualified for space applications?
JANTX1N4113D-1 is qualified to MIL-PRF-19500/435 JANTX level and exhibits inherent radiation hardness per Microsemi MicroNote 050. While not fully QML-V certified, it is widely used in LEO satellite power systems where TID tolerance and thermal stability are required - full space qualification requires additional lot-specific testing.
What is the maximum operating temperature for JANTX1N4113D-1?
JANTX1N4113D-1 supports a junction temperature range of -65 °C to +175 °C. Its power dissipation must be linearly derated from 500 mW at 25 °C to zero at 175 °C, enabling reliable operation in engine bay electronics, downhole tools, and avionics bays without forced cooling.
Does JANTX1N4113D-1 have low noise performance?
Yes, JANTX1N4113D-1 delivers 1 µV/√Hz noise density at 250 mA, among the lowest in its voltage class. This performance is confirmed in Figure 1 of the T4-LDS-0245-2 datasheet and makes JANTX1N4113D-1 suitable for precision analog front-ends where reference noise directly impacts system resolution.
How is polarity marked on JANTX1N4113D-1?
JANTX1N4113D-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation. This marking complies with JEDEC DO-35 standards and is visible on the glass body adjacent to the lead exit point.
