Product details
Overview
1N4110-1 from Microsemi is a 500 mW, 16.0 V Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 5% voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and maximum reverse leakage of 0.05 µA at 12.2 V. It delivers stable voltage regulation in precision reference and power supply feedback circuits.
For engineers reviewing the 1N4110-1 datasheet, 1N4110-1 pinout, 1N4110-1 application, or 1N4110-1 equivalent, this page provides verified electrical parameters, military-grade qualification status, thermal derating behavior, noise density (1 µV/√Hz), and direct alternatives for high-reliability analog design.
Technical Context
The 1N4110-1 operates as a two-terminal voltage reference device in reverse breakdown mode, with cathode band indicating polarity. Its metallurgically bonded construction ensures low noise and radiation hardness per MicroNote 050, and its DO-35 hermetic glass package supports operation from –65 °C to +175 °C junction temperature.
It exhibits a positive temperature coefficient of +0.085 %/°C, enabling predictable drift compensation in temperature-stable references. Power dissipation linearly derates from 500 mW at 25 °C ambient to zero at 175 °C, with RθJA = 300 °C/W on standard FR4 board layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 16.0 V at 250 mA - precise regulation point for mid-range reference designs |
| Power Rating PM(AV) | 0.5 W - supports continuous operation up to 25 °C ambient before linear derating begins |
| Dynamic Impedance ZZT | 100 Ω at IZT = 250 mA - low AC impedance ensures minimal output voltage variation under load transients |
| Reverse Leakage IR | 0.05 µA at VR = 12.2 V - ultra-low leakage preserves accuracy in high-impedance bias networks |
| Noise Density ND | 1 µV/√Hz - lowest noise in its voltage range, critical for low-noise instrumentation references |
| Temp Coefficient αVZ | +0.085 %/°C - enables predictable thermal drift modeling in compensated circuits |
| Junction Temp Range | –65 °C to +175 °C - suitable for aerospace, downhole, and extended-temperature industrial systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4110UR-1 | Same electrical specs; DO-213AA surface-mount package instead of DO-35 axial lead | Required for automated SMT assembly; lacks axial mounting flexibility | Select when PCB space constraints or reflow-only manufacturing prohibit through-hole placement |
| 1N4745A | 16 V nominal, but 5% tolerance only; no military qualification; RθJA = 500 °C/W; ND = 1.5 µV/√Hz | Commercial-grade use only; unsuitable for aerospace or extended-temperature environments | Acceptable for cost-sensitive consumer power supplies where radiation hardness and wide temp range are not required |

FAQ
What is the Zener voltage tolerance for the 1N4110-1?
The 1N4110-1 has a nominal Zener voltage of 16.0 V with a standard tolerance of ±5%, as defined by JEDEC registration and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. No tighter tolerance (e.g., 2% or 1%) is specified for this specific part number in the documentation.
Is the 1N4110-1 RoHS compliant?
Yes, RoHS-compliant versions of the 1N4110-1 are available with the "e3" suffix (e.g., 1N4110-1e3), as stated in the nomenclature section on page 2. These versions feature annealed matte-tin plating and are offered for commercial-grade use only-not for JAN/JANTX/JANTXV/JANS reliability levels.
What is the maximum reverse leakage current for the 1N4110-1?
The 1N4110-1 has a maximum reverse leakage current (IR) of 0.05 µA measured at VR = 12.2 V, per the Electrical Characteristics table on page 3. This ultra-low leakage supports high-impedance reference designs without significant error contribution.
Does the 1N4110-1 require heatsinking in typical operation?
No additional heatsinking is required for the 1N4110-1 at ambient temperatures ≤25 °C and power dissipation ≤500 mW. Its RθJA = 300 °C/W assumes standard FR4 mounting (1 oz Cu, 4 mm² pads); derating begins linearly above 25 °C ambient, reaching zero dissipation at 175 °C.
How does the 1N4110-1 compare to the 1N4109-1 in terms of temperature coefficient?
The 1N4110-1 has a temperature coefficient of +0.085 %/°C, identical to the 1N4109-1 (15.0 V variant), as both appear in the same row group in the Electrical Characteristics table. This consistent positive TC enables predictable drift matching across adjacent voltage grades in multi-rail reference designs.
