Product details
Overview
JANTX1N4099C-1 from Microsemi is a 500 mW, 6.8 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and +0.060 %/°C temperature coefficient - used for precision voltage reference and regulation in military power supply monitoring circuits.
For engineers reviewing the JANTX1N4099C-1 datasheet, JANTX1N4099C-1 pinout, JANTX1N4099C-1 application, or JANTX1N4099C-1 equivalent, this page delivers verified electrical specs, thermal derating behavior, noise density (40 µV/√Hz), RoHS compliance status (non-RoHS, JANTX grade), and direct alternatives with documented voltage/tolerance/package alignment.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction for high-reliability performance. It maintains stable 6.8 V output across 5.2 mA to 75 mA operating current range and exhibits low noise density (40 µV/√Hz) above 6.8 V, with minimal capacitance (<2 pF typical) and inherent radiation hardness per MicroNote 050.
Thermal design requires linear derating from 500 mW at 25 °C ambient to zero at 175 °C, with junction-to-lead thermal resistance of 250 °C/W at 10 mm lead length. Polarity is marked by cathode band; regulation occurs with banded end positive relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.8 V ±2% at 250 mA - defines precise regulation point for feedback loops and reference rails |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - sets maximum continuous thermal load on PCB |
| Dynamic Impedance ZZT | 200 Ω at IZT = 250 mA - determines output voltage stability under load transients |
| Noise Density | 40 µV/√Hz - critical for low-noise analog references and sensor excitation circuits |
| Temp Coefficient αVZ | +0.060 %/°C - enables predictable drift compensation in wide-temperature military systems |
| Reverse Leakage IR | 1.0 µA at VR = 5.2 V - ensures minimal quiescent current in standby regulation paths |
| Junction Temp Range | –65 °C to +175 °C - supports operation in aerospace, downhole, and engine bay environments |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package; cathode indicated by single black band; anode and cathode leads are tin-lead plated and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference Ground Node | Connected to system ground or lower-potential rail; forms return path for Zener current |
| Cathode (banded end) | Regulated Output Terminal | Provides stable 6.8 V output when reverse biased; must be held at higher potential than anode |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical Bond Construction | Enables JANTX-level reliability and long-term stability under thermal cycling and vibration |
| MIL-PRF-19500/435 Qualification | Validates performance for defense/aerospace applications requiring traceable lot control and screening |
| Low Capacitance (~2 pF) | Minimizes high-frequency loading in RF bias networks and fast-switching regulator feedback paths |
| Radiation Hardness | Inherent tolerance to total ionizing dose (TID), supporting use in space-qualified subsystems per MicroNote 050 |
| ESD Robustness | Non-sensitive per MIL-STD-750 Method 1020 - eliminates need for external ESD protection in handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4099UR-1 | Same 6.8 V ±2% Zener voltage, but in DO-213AA surface-mount package instead of DO-35 axial. | Used where board space is constrained and reflow assembly is required; lacks axial mounting flexibility. | Select for automated SMT production; verify thermal pad layout matches RθJL = 250 °C/W requirement. |
| JAN1N4099C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX). | Suitable for cost-sensitive defense programs where full JANTX screening is not mandated by spec. | Choose when MIL-PRF-19500/435 Class B (JAN) suffices; no PCB changes required vs. JANTX1N4099C-1. |
Compared with JANTX1N4099C-1, the 1N4099UR-1 enables miniaturized layouts but sacrifices axial mechanical robustness, while the JAN1N4099C-1 reduces procurement cost and test overhead without altering circuit performance or footprint.

FAQ
What is the Zener voltage tolerance and test current for JANTX1N4099C-1?
JANTX1N4099C-1 has a nominal Zener voltage of 6.8 V with ±2% tolerance, measured at a Zener test current (IZT) of 250 mA. This tolerance is achieved through tighter process control versus standard 5% variants, and the 250 mA test point ensures regulation stability under moderate load conditions typical in reference circuits.
Is JANTX1N4099C-1 RoHS compliant?
No, JANTX1N4099C-1 is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0245-2, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTX-level devices like JANTX1N4099C-1 retain tin-lead plating to meet MIL-STD-750 solderability requirements and reliability screening standards.
What is the maximum Zener current (IZM) for JANTX1N4099C-1?
The maximum Zener current IZM for JANTX1N4099C-1 is 75 mA. This value derives from the 500 mW power rating and 6.8 V Zener voltage (P = V × I → I = 0.5 W / 6.8 V ≈ 73.5 mA), rounded to 75 mA per the datasheet's Electrical Characteristics table, and assumes operation within thermal derating limits.
How does the temperature coefficient affect JANTX1N4099C-1 in wide-temperature applications?
JANTX1N4099C-1 has a temperature coefficient of +0.060 %/°C, meaning its Zener voltage increases by approximately 4.08 mV per °C rise. Over a –55 °C to +125 °C range, this yields ~1.09 V total drift - a known, linear offset that can be compensated in system calibration, making it predictable for high-accuracy military instrumentation.
Can JANTX1N4099C-1 replace commercial 1N4099C-1 in existing designs?
Yes, JANTX1N4099C-1 is a direct functional and mechanical replacement for commercial 1N4099C-1, sharing identical Zener voltage, tolerance, package (DO-35), and pinout. However, JANTX qualification adds enhanced screening, traceability, and guaranteed performance across –65 °C to +175 °C, making it suitable for upgraded reliability requirements without layout changes.
