Product details
Overview
JAN1N4116C-1 from Microsemi is a 500 mW, 24.0 V ±2% metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 150 Ω dynamic impedance and +0.090 %/°C temperature coefficient, used in precision reference and power supply feedback circuits.
For engineers reviewing the JAN1N4116C-1 datasheet, JAN1N4116C-1 pinout, JAN1N4116C-1 application, or JAN1N4116C-1 equivalent, key selection factors include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), junction temperature range (–65 to +175 °C), thermal resistance (250 °C/W), and military-grade reliability qualification.
Technical Context
This Zener diode operates in reverse breakdown mode with cathode band indicating polarity, requiring banded end to be positive for regulation. Its metallurgical bond construction ensures low noise and high reliability under thermal cycling and radiation exposure.
It exhibits minimal capacitance (<1 pF typical at 24 V), low leakage (≤0.01 µA at 18.3 V), and linear power derating from 500 mW at 25 °C to zero at 175 °C - critical for high-temperature avionics and space-qualified power conditioning.
Key Specifications

|---|---|
| Zener Voltage VZ | 24.0 V ±2% at 250 mA - enables precise 24 V rail regulation with tight tolerance for feedback loops. |
| Power Dissipation | 500 mW at 25 °C lead temperature - supports continuous operation in compact axial-leaded layouts with 3/8″ lead length. |
| Dynamic Impedance ZZT | 150 Ω at 250 mA - ensures stable output under load transients in regulated DC-DC converters. |
| Noise Density | 1 µV/√Hz at 24 V - critical for low-noise analog references and sensor excitation circuits. |
| Temp. Coefficient αVZ | +0.090 %/°C - predictable drift behavior over –65 to +175 °C for aerospace thermal management. |
| Reverse Leakage IR | ≤0.01 µA at 18.3 V - minimizes standby current loss in battery-backed systems. |
| Junction Temp. Range | –65 to +175 °C - validated for extended-range operation in missile guidance and satellite power systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap. | Select when automated assembly and board space constraints outweigh manual repair needs. |
| JANTXV1N4116C-1 | Identical Zener parameters but qualified to JANTXV level with enhanced screening (burn-in, thermal shock, life test). | Required for Class H (spaceflight) and Class K (strategic weapons) programs per MIL-PRF-19500. | Select when mission-critical reliability exceeds JAN-level requirements and budget permits premium screening. |
Compared with JAN1N4116C-1, the 1N4116US-1 offers identical regulation performance in a smaller footprint but eliminates field-replaceability, while JANTXV1N4116C-1 adds rigorous environmental testing at higher cost - enabling trade-offs between manufacturability, repairability, and mission assurance.

FAQ
What is the Zener voltage tolerance for JAN1N4116C-1?
JAN1N4116C-1 has a nominal Zener voltage of 24.0 V with ±2% tolerance, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, supporting tight regulation in feedback networks where deviation beyond ±0.48 V is unacceptable.
Is JAN1N4116C-1 RoHS compliant?
No, JAN1N4116C-1 is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4116C-1e3); JAN-level parts retain traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS restrictions due to their military qualification status.
What is the maximum junction temperature for JAN1N4116C-1?
JAN1N4116C-1 has a rated junction and storage temperature range of –65 to +175 °C, validated per MIL-PRF-19500/435. This allows operation in extreme environments such as engine-mounted avionics or orbital satellite power systems without derating until 175 °C.
How does the thermal resistance of JAN1N4116C-1 affect PCB layout?
JAN1N4116C-1 has RθJL = 250 °C/W with 3/8″ (10 mm) lead length. To maintain safe junction temperature, PCB traces must provide adequate copper area (≥4 mm² pads, 1 mm wide × 25 mm long) and avoid thermal isolation - especially in convection-cooled military chassis.
Can JAN1N4116C-1 replace commercial 1N4116C-1 in existing designs?
Yes, JAN1N4116C-1 is a direct form-fit-function replacement for commercial 1N4116C-1, sharing identical electrical parameters, DO-35 package dimensions, and pinout. However, it adds JAN-level screening, traceability, and extended temperature validation - making it suitable for upgrading legacy designs to meet defense procurement requirements.
