Product details
Overview
JAN1N4110-1/TR from Microsemi is a 500 mW, 16 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JAN reliability level per MIL-PRF-19500/435, with ±5% voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and 0.05 µA maximum reverse leakage at 12.2 V. It serves as a precision reference in military-grade power supply regulation and analog circuit biasing.
For engineers reviewing the JAN1N4110-1/TR datasheet, JAN1N4110-1/TR pinout, JAN1N4110-1/TR application, or JAN1N4110-1/TR equivalent, key selection criteria include its MIL-qualified reliability grade, 16 V nominal Zener voltage with temperature coefficient of +0.085 %/°C, low noise density (≤1 µV/√Hz below 6.8 V), hermetic DO-35 packaging, and compatibility with through-hole PCB assembly requiring stable voltage references under extended temperature ranges.
Technical Context
This device operates in reverse breakdown mode with cathode band indicating polarity, requiring banded end to be held positive relative to anode for regulation. Its metallurgically bonded junction ensures stable Zener voltage over time and temperature, supporting operation from –65 °C to +175 °C junction temperature.
The diode exhibits 100 Ω dynamic impedance (ZZT) at IZT = 250 mA, 0.05 µA reverse leakage (IR) at VR = 12.2 V, and a linear power derating curve from 500 mW at 25 °C ambient down to zero at 175 °C - critical for thermal design in high-reliability embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 16.0 V at 250 mA test current - defines precise regulation point for reference circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4110US-1 | Same 16 V Zener voltage and JAN qualification, but in surface-mount DO-213AA package | Requires SMT reflow process instead of through-hole wave soldering; no lead-forming needed | Select when board space constraints or automated assembly favor SMT over axial-leaded components |
| JANTXV1N4110-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening and tighter lot traceability | Required for mission-critical subsystems where burn-in, life test, and lot-specific data are mandated | Select when program specifications require JANTXV-level reliability documentation and screening |
Compared with JAN1N4110-1/TR, the 1N4110US-1 offers identical regulation performance in a space-saving SMT form factor, while JANTXV1N4110-1 provides higher assurance via extended environmental stress screening - enabling trade-offs between manufacturability, footprint, and qualification rigor.

FAQ
What is the Zener voltage tolerance for JAN1N4110-1/TR?
JAN1N4110-1/TR has a nominal Zener voltage of 16.0 V with a standard ±5% tolerance per JEDEC registration and MIL-PRF-19500/435 specification. This tolerance applies at 25 °C with thermal equilibrium and defines the allowable deviation in regulation voltage under specified test conditions.
Is JAN1N4110-1/TR RoHS compliant?
No, JAN1N4110-1/TR is not RoHS compliant. The "TR" suffix indicates tape-and-reel packaging, but RoHS compliance (denoted by "e3") is only available on commercial-grade versions of this series, not on JAN-qualified parts. JAN1N4110-1/TR uses traditional tin-lead plating per MIL-STD-750.
What is the maximum reverse leakage current for JAN1N4110-1/TR?
The maximum reverse leakage current (IR) for JAN1N4110-1/TR is 0.05 µA measured at VR = 12.2 V (80% of nominal Zener voltage). This value is specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet and reflects tight leakage control essential for high-impedance bias networks.
Does JAN1N4110-1/TR require heatsinking in typical operation?
No, JAN1N4110-1/TR does not require external heatsinking under typical 500 mW operation at ambient temperatures ≤50 °C. Its thermal resistance junction-to-ambient is 300 °C/W on FR4 board, and power derating begins linearly above 50 °C - heatsinking becomes relevant only in high-temperature enclosures or sustained >300 mW dissipation.
How is polarity marked on JAN1N4110-1/TR?
Polarity on JAN1N4110-1/TR is marked by a single black cathode band on the glass body. The banded end is the cathode and must be held positive with respect to the unmarked (anode) end to achieve Zener regulation. This marking follows JEDEC DO-35 standard and is verified in the Mechanical and Packaging section of the datasheet.
