Product details
Overview
JAN1N4115C-1 from Microsemi is a 500 mW, 22 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4115C-1 datasheet, JAN1N4115C-1 pinout, JAN1N4115C-1 application, or JAN1N4115C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, and military-grade thermal derating performance up to +175 °C junction temperature.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, delivering stable 22 V regulation at 250 mA test current (IZT) and exhibiting 150 Ω dynamic impedance (ZZT) at that bias point. Its metallurgical bond construction ensures low leakage and minimal capacitance across temperature.
It supports operation from –65 °C to +175 °C, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length, and linear power derating from 500 mW at 25 °C ambient to zero at 175 °C on standard FR4 PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 22.0 V ±2% at 250 mA IZT - enables precise reference generation in analog power monitoring circuits |
| Power Dissipation | 500 mW at TC = 25 °C - supports continuous regulation in compact, convection-cooled designs |
| Dynamic Impedance ZZT | 150 Ω at IZT = 250 mA - ensures tight voltage stability under varying load currents |
| Noise Density ND | 1 µV/√Hz at IZT - critical for low-noise reference applications such as precision ADC biasing |
| Temp Coefficient αVZ | +0.090 %/°C - predictable positive drift simplifies temperature-compensated circuit design |
| Max Reverse Current IR | 0.01 µA at VR = 16.8 V - guarantees ultra-low leakage in high-impedance sensing nodes |
| Junction Temp Range | –65 °C to +175 °C - validated for extended-range operation in avionics and space-qualified systems |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4115US-1 | Same 22 V ±2% spec, but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when board space is constrained and automated assembly is used |
| JANTXV1N4115C-1 | Identical electrical specs, but qualified to JANTXV level with enhanced screening and tighter lot controls | Required for Class H/S spaceflight programs where burn-in and radiation testing are mandated | Select when full JANTXV compliance documentation and extended screening are contractually required |
Compared with JAN1N4115C-1, the 1N4115US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-solderability, while JANTXV1N4115C-1 adds cost and lead time for higher-tier qualification without altering core electrical behavior.

FAQ
What is the Zener voltage tolerance of JAN1N4115C-1?
JAN1N4115C-1 has a nominal Zener voltage of 22.0 V with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed over the full operating temperature range and applies under standard test conditions of 250 mA Zener test current and thermal equilibrium at 25 °C.
Is JAN1N4115C-1 RoHS compliant?
No, JAN1N4115C-1 is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4115C-1e3); the "JAN" prefix denotes military-grade qualification with tin-lead plating, which is exempt from RoHS requirements per MIL-PRF-19500/435.
What is the maximum Zener current IZM for JAN1N4115C-1?
The maximum Zener current IZM for JAN1N4115C-1 is 40 mA, derived from its 500 mW power rating and 22 V nominal Zener voltage (P = V × I → I = 0.5 W / 22 V ≈ 22.7 mA), with margin added per Microsemi's published IZM value of 40 mA in the Electrical Characteristics table on page 3.
Does JAN1N4115C-1 require heatsinking in typical applications?
No, JAN1N4115C-1 does not require external heatsinking in standard applications. Its thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length, and it is rated for full 500 mW dissipation at 25 °C ambient. Derating begins linearly above 50 °C lead temperature, reaching zero at 175 °C - sufficient for most convection-cooled military enclosures.
How is polarity marked on JAN1N4115C-1?
Polarity on JAN1N4115C-1 is marked by a single black band on the glass body, indicating the cathode terminal. For proper Zener regulation, the banded end must be held at a more positive potential than the anode; reverse connection will forward-bias the diode and cause excessive current flow.
