Product details
Overview
JANTX1N4115C-1 from Microsemi is a 500 mW, 22.0 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4115C-1 datasheet, JANTX1N4115C-1 pinout, JANTX1N4115C-1 application, or JANTX1N4115C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and JANTX-level qualification for extended temperature operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 22.0 V at 250 mA test current, exhibiting low dynamic impedance (150 Ω) and minimal noise density (1 µV/√Hz) due to its metallurgical bond construction. Its positive temperature coefficient (+0.090 %/°C) ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability environments, JANTX1N4115C-1 meets MIL-PRF-19500/435 requirements including hermetic glass sealing, non-ESD-sensitive behavior per MIL-STD-750 Method 1020, and radiation hardness per Microsemi MicroNote 050 - enabling use in avionics power conditioning and satellite subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 22.0 V ±2% at IZT = 250 mA - defines precise regulation point under standard test conditions |
| Power Dissipation | 500 mW at TL = 25 °C, derated linearly to zero at 175 °C - sets maximum thermal load on PCB traces |
| Dynamic Impedance ZZT | 150 Ω @ 250 mA - determines output voltage stability under varying load current |
| Noise Density | 1 µV/√Hz - enables low-noise reference in precision analog circuits |
| Temperature Coefficient αVZ | +0.090 %/°C - quantifies drift rate of regulation voltage over temperature |

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 Zener voltage and ±2% tolerance, but in surface-mount DO-213AA package | Requires rework of PCB layout for SMT assembly; lacks axial lead flexibility for prototyping or through-hole repair | Select when automated assembly and board space constraints outweigh manual serviceability needs |
| JAN1N4115C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Not approved for mission-critical flight hardware requiring full JANTX documentation and lot traceability | Select only for ground-test or non-flight qualification prototypes where cost reduction is prioritized |
Compared with JANTX1N4115C-1, the 1N4115US-1 offers identical regulation performance in a compact SMT form factor but sacrifices mechanical robustness and repairability, while JAN1N4115C-1 reduces qualification overhead at the expense of flight-worthiness assurance.

FAQ
What is the Zener voltage tolerance of JANTX1N4115C-1?
JANTX1N4115C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a nominal 22.0 V regulation point ranging from 21.56 V to 22.44 V at 250 mA test current and 25 °C ambient, enabling tighter system-level voltage margining than standard ±5% variants.
Is JANTX1N4115C-1 suitable for space applications?
Yes, JANTX1N4115C-1 is radiation-hardened per Microsemi MicroNote 050 and qualified to MIL-PRF-19500/435 JANTX level, making it suitable for low-earth orbit (LEO) satellite subsystems. Its hermetic DO-35 package and metallurgical bond construction provide proven reliability under total ionizing dose (TID) exposure, though full radiation testing reports must be obtained from Microchip for specific mission profiles.
What is the maximum reverse leakage current for JANTX1N4115C-1?
The maximum reverse leakage current for JANTX1N4115C-1 is 0.01 µA at VR = 16.8 V, as specified in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance bias networks in precision analog circuits without introducing measurable error.
Does JANTX1N4115C-1 require derating above 25 °C ambient?
Yes, JANTX1N4115C-1 must be derated linearly from 500 mW starting at 25 °C ambient temperature, reaching zero dissipation at 175 °C, per Figure 2 in the datasheet. For example, at 75 °C ambient, maximum allowable power drops to 375 mW - a critical consideration for thermally constrained avionics enclosures.
How is polarity marked on JANTX1N4115C-1?
JANTX1N4115C-1 uses a cathode band marking on the glass body to indicate polarity. The banded end is the cathode and must be held at a higher potential than the anode to achieve Zener breakdown regulation. This marking aligns with JEDEC DO-35 standards and is verified per MIL-STD-750 Method 2026 visual inspection requirements.
