Product details
Overview
JANS1N4110-1/TR from Microsemi is a 16 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±5% Zener voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4110-1/TR datasheet, JANS1N4110-1/TR pinout, JANS1N4110-1/TR application, or JANS1N4110-1/TR equivalent, key selection criteria include radiation-hardened performance, low noise density (1 µV/√Hz), hermetic DO-35 packaging, and compliance with military reliability screening levels up to JANS.
Technical Context
This device functions as a precision voltage reference and regulation element in analog power supply rails, bias networks, and overvoltage protection circuits where long-term stability under thermal and radiation stress is required. Its internal metallurgical bond ensures mechanical robustness and low parameter drift over time.
The JANS1N4110-1/TR exhibits a positive temperature coefficient of +0.085 %/°C, enabling predictable voltage shift with temperature-critical for compensated reference designs. It maintains ≤0.05 µA reverse leakage at 14 V and supports stable regulation from 12.2 mA to 40 mA Zener current.
Key Specifications

|---|---|
| Zener Voltage VZ | 16.0 V ±5% at 250 mA - defines nominal regulation point with tight production control for reference accuracy |
| Power Dissipation | 500 mW @ TL = 25 °C - sets maximum continuous DC power handling before thermal derating begins |
| Dynamic Impedance ZZT | 100 Ω @ IZT = 250 mA - determines output voltage variation under load current changes |
| Noise Density | 1 µV/√Hz - enables low-noise reference use in precision instrumentation and ADC biasing |
| Reverse Leakage IR | ≤0.05 µA @ VR = 14 V - ensures minimal parasitic current in high-impedance sensing nodes |
| Temp. Coefficient αVZ | +0.085 %/°C - allows predictable voltage drift compensation in wide-temperature environments |
| Junction Temp. Range | –65 °C to +175 °C - supports 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 |
|---|---|---|---|
| 1N4110US-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 board space is constrained and automated placement is available |
| JANTXV1N4110-1 | Identical Zener parameters but qualified only to JANTXV level; lacks JANS-level radiation assurance and extended life testing | Acceptable for ground-based military systems but not certified for flight-critical avionics or space missions | Select when full JANS screening is not mandated by program requirements |
Compared with JANS1N4110-1/TR, the 1N4110US-1 offers identical regulation performance in a compact SMT form factor, while the JANTXV1N4110-1 provides cost savings where JANS-level radiation hardness and extended reliability testing are unnecessary.

FAQ
What is the Zener voltage tolerance for JANS1N4110-1/TR?
The JANS1N4110-1/TR has a nominal Zener voltage of 16.0 V with a ±5% tolerance, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This tolerance applies at 25 °C with 250 mA test current and reflects the standard JAN/JANS grade specification for this series.
Is JANS1N4110-1/TR RoHS compliant?
No, JANS1N4110-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of the datasheet, the "e3" suffix denotes RoHS compliance, which is available only on commercial-grade versions. The JANS1N4110-1/TR uses tin-lead plating and conforms to military specifications that exempt it from RoHS requirements.
What is the maximum Zener current rating for JANS1N4110-1/TR?
The maximum Zener current (IZM) for JANS1N4110-1/TR is 40 mA, as listed in the Electrical Characteristics table. This value corresponds to the current at which the device reaches its rated 500 mW power dissipation limit at 25 °C lead temperature, assuming VZ ≈ 16 V.
Does JANS1N4110-1/TR require derating above 25 °C?
Yes, JANS1N4110-1/TR must be linearly derated starting at 25 °C ambient temperature on a typical PCB, reaching zero power dissipation at 175 °C. Derating follows a slope of –3.33 mW/°C, based on the 500 mW rating and 150 °C usable range above 25 °C, as shown in Figure 2 of the datasheet.
What does the "TR" suffix indicate in JANS1N4110-1/TR?
The "TR" suffix in JANS1N4110-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated surface-mount assembly equipment. It does not affect electrical or reliability specifications-JANS1N4110-1/TR retains full JANS qualification and DO-35 axial-lead construction.
