Product details
Overview
JAN1N4111C-1/TR from Microsemi is a 500 mW, 17.0 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JAN reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and maximum reverse leakage of 0.05 µA at 13.0 V. It delivers stable regulation in precision reference and power supply feedback circuits across military temperature range.
For engineers reviewing the JAN1N4111C-1/TR datasheet, JAN1N4111C-1/TR pinout, JAN1N4111C-1/TR application, or JAN1N4111C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), JANS-qualified thermal stability (–65 °C to +175 °C), and metallurgically bonded construction for high-reliability aerospace and defense systems.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining a stable 17.0 V output by conducting reverse current above its breakdown knee (IZK = 250 mA). Its internal metallurgical bond ensures low thermal resistance (RθJL = 250 °C/W) and radiation hardness per MicroNote 050.
The diode exhibits a positive temperature coefficient of +0.090 %/°C and minimal capacitance (<1.5 pF at 17 V), enabling use in low-noise analog references and high-frequency voltage clamping where parasitic effects must be minimized.
Key Specifications

|---|---|
| Zener Voltage VZ | 17.0 V ±2% at IZT = 250 mA - precise reference point for feedback loops requiring tight regulation tolerance. |
| Power Dissipation | 500 mW at TL = 25 °C, linearly derated to zero at 175 °C - supports continuous operation in high-temp environments with proper lead heatsinking. |
| Dynamic Impedance ZZT | 100 Ω max at IZT = 250 mA - ensures minimal output voltage variation under load transients in regulated supplies. |
| Reverse Leakage IR | 0.05 µA max at VR = 13.0 V - enables ultra-low standby current in battery-backed reference circuits. |
| Noise Density | 1 µV/√Hz at IZT = 250 mA - critical for low-noise instrumentation amplifiers and precision ADC references. |
| Temp Coefficient αVZ | +0.090 %/°C - predictable drift behavior allows accurate compensation in wide-temperature-range designs. |
| Junction Temp Range | –65 °C to +175 °C - meets MIL-PRF-19500/435 JAN-level requirements for space and avionics applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1 | Same Zener voltage (17.0 V) and tolerance (±2%), but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow assembly is required; lacks axial mounting flexibility. | Select when automated SMT production is mandatory and thermal coupling to PCB copper is acceptable. |
| JANTXV1N4111C-1 | Identical electrical specs and DO-35 package, but qualified to higher JANTXV reliability level with extended screening and 100% lot testing. | Required for Class H avionics or systems demanding zero latent defects; adds cost and lead time. | Select when failure-in-service risk must be reduced below JAN-level statistical limits for human-rated platforms. |
Compared with JAN1N4111C-1/TR, the 1N4111US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4111C-1 provides enhanced screening rigor for ultra-high-integrity applications-neither is pin-compatible due to differing packages or qualification scope, and both require design validation for thermal and reliability margins.

JAN1N4111C-1/TR has a nominal Zener voltage of 17.0 V with a ±2% tolerance, measured at IZT = 250 mA and 25 °C. This C-grade tolerance enables tighter system-level voltage accuracy without post-manufacturing trimming, and is confirmed in Microsemi's T4-LDS-0245-2 datasheet Table on Page 3.
Is JAN1N4111C-1/TR qualified to MIL-PRF-19500 standards?
Yes, JAN1N4111C-1/TR is qualified to MIL-PRF-19500/435 at the JAN reliability level, including full environmental screening, lot acceptance testing, and traceable documentation. The "JAN" prefix in the part number explicitly denotes this qualification, as defined in the Part Nomenclature section of the T4-LDS-0245-2 datasheet.
What is the maximum reverse leakage current for JAN1N4111C-1/TR?
JAN1N4111C-1/TR has a maximum reverse leakage current (IR) of 0.05 µA at VR = 13.0 V, per the Electrical Characteristics table on Page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports energy-efficient reference designs and extends battery life in always-on monitoring systems.
Does JAN1N4111C-1/TR have radiation hardness?
Yes, JAN1N4111C-1/TR exhibits inherent radiation hardness due to its metallurgically bonded construction and hermetic DO-35 glass package, as documented in Microsemi MicroNote 050. It is routinely deployed in satellite and nuclear instrumentation applications where total ionizing dose tolerance exceeds 100 krad(Si).
What is the noise density specification for JAN1N4111C-1/TR?
JAN1N4111C-1/TR has a maximum noise density of 1 µV/√Hz at IZT = 250 mA, as specified in the Electrical Characteristics table on Page 3 of the T4-LDS-0245-2 datasheet. This value applies to the 1 kHz–3 kHz measurement bandwidth and makes it suitable for low-noise analog reference applications.
