Product details
Overview
JANTX1N4116C-1/TR from Microsemi is a 24.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4116C-1/TR datasheet, JANTX1N4116C-1/TR pinout, JANTX1N4116C-1/TR application, or JANTX1N4116C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), dynamic impedance (150 Ω at 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and JANTX-level qualification for extended temperature operation.
Technical Context
This axial-leaded Zener diode operates in reverse breakdown with cathode band indicating polarity, requiring banded end to be positive relative to anode for regulation. It delivers stable 24.0 V reference under DC current from 18.3 mA to 40 mA, with low noise density and minimal capacitance across its operating range.
Its metallurgical bond construction ensures robust thermal performance (RθJL = 250 °C/W) and radiation hardness per Microsemi MicroNote 050. The device is rated for junction temperatures from –65 °C to +175 °C and linearly derates 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 ±2% at 250 mA - precise reference for mid-range analog power rails |
| Power Dissipation | 500 mW @ TL = 25 °C - supports compact through-hole regulator designs without heatsinking |
| Zener Impedance ZZT | 150 Ω max at IZT = 250 mA - ensures low output impedance for stable regulation under load transients |
| Noise Density | 1 µV/√Hz - enables use in low-noise precision references and sensor excitation circuits |
| Temp Coefficient αVZ | +0.090 %/°C - predictable positive drift simplifies temperature compensation in wide-temp environments |
| Reverse Leakage IR | 0.01 µA @ VR = 18.3 V - negligible quiescent current in standby or battery-backed systems |
| Forward Voltage VF | 1.1 V @ 200 mA - allows safe forward conduction during transient overvoltage events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4116C-1/TR | JANTXV qualification level with tighter screening and extended temperature validation beyond JANTX | Suitable for mission-critical avionics where failure modes require higher confidence in parametric stability | Select when full JANTXV compliance is mandated by system-level reliability requirements |
| 1N4116C-1/TR | Commercial-grade version without MIL-PRF-19500 qualification; same electrical specs and DO-35 package | Applicable in non-military industrial or test equipment where cost sensitivity outweighs military screening needs | Choose for prototyping or volume production where JANTX-level traceability is not required |
Compared with JANTX1N4116C-1/TR, the JANTXV variant adds enhanced screening for extreme environments while the commercial 1N4116C-1/TR retains identical Zener characteristics but omits military qualification-enabling trade-offs between reliability assurance and procurement cost.

FAQ
What is the Zener voltage and tolerance of JANTX1N4116C-1/TR?
JANTX1N4116C-1/TR has a nominal Zener voltage of 24.0 V with a tight ±2% tolerance at 250 mA test current. This tolerance is denoted by the "C" suffix in the part number and is verified per MIL-PRF-19500/435 screening. The device maintains this specification across its qualified operating temperature range of –65 °C to +175 °C, making JANTX1N4116C-1/TR suitable for high-stability reference applications.
Is JANTX1N4116C-1/TR RoHS compliant?
No, JANTX1N4116C-1/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (e.g., with e3 suffix) are available only for commercial-grade parts like 1N4116C-1e3/TR-not for JANTX-level devices. JANTX1N4116C-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements and ensure compatibility with legacy aerospace assembly processes.
What is the maximum Zener current IZM for JANTX1N4116C-1/TR?
The maximum Zener current IZM for JANTX1N4116C-1/TR is 40 mA, derived from its 500 mW power rating and 24.0 V Zener voltage (P = V × I → I = 0.5 W / 24 V ≈ 20.8 mA), with margin applied per derating curves. The datasheet specifies 40 mA as the absolute maximum DC current under thermal equilibrium conditions at 25 °C lead temperature-exceeding this risks thermal runaway and permanent degradation of JANTX1N4116C-1/TR.
How does the temperature coefficient affect JANTX1N4116C-1/TR in real-world operation?
JANTX1N4116C-1/TR has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 21.6 mV per °C rise above 25 °C. In a –55 °C to +125 °C environment, this results in a total shift of ~13.5 V, but actual regulation remains stable due to circuit-level compensation. This predictable positive drift makes JANTX1N4116C-1/TR easier to compensate than negative-coefficient Zeners in wide-temperature applications.
Can JANTX1N4116C-1/TR be used as a replacement for commercial 1N4116-1?
JANTX1N4116C-1/TR is electrically compatible with commercial 1N4116-1 but not a drop-in replacement due to qualification differences. While both share 24.0 V Zener voltage and DO-35 package, JANTX1N4116C-1/TR includes JANTX-level screening, tighter 2% tolerance (vs. 5% for standard 1N4116-1), and military-grade plating. Substituting JANTX1N4116C-1/TR into a commercial design adds cost and qualification overhead unless reliability requirements demand it.
