Product details
Overview
JANTXV1N4115C-1 from Microsemi is a 500 mW, 22 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4115C-1 datasheet, JANTXV1N4115C-1 pinout, JANTXV1N4115C-1 application, or JANTXV1N4115C-1 equivalent, key selection factors include its 22 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA max reverse leakage at 16.8 V, and radiation-hardened hermetic construction.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 22.0 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.090 %/°C and low noise density (1 µV/√Hz typical). Its metallurgical bond ensures stable breakdown characteristics under thermal cycling.
The JANTXV1N4115C-1 is rated for junction temperatures 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 to zero at 175 °C.

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, DO-213AA surface-mount package, no MIL qualification | Limited to commercial-grade PCB assemblies without hermetic sealing or radiation requirements | Select for cost-sensitive, high-volume SMT production where JANTXV reliability is not mandated |
| JAN1N4115C | Identical electrical specs and DO-35 package, but qualified only to JAN (not JANTXV) level per MIL-PRF-19500/435 | Suitable for less demanding military programs where full JANTXV screening is unnecessary | Choose when lifecycle assurance and extended burn-in testing are not required, reducing procurement cost |
Compared with JANTXV1N4115C-1, the 1N4115US-1 offers SMT compatibility but lacks hermeticity and radiation hardness, while JAN1N4115C provides identical performance with reduced reliability screening - both require revalidation if replacing JANTXV1N4115C-1 in flight-critical designs.

FAQ
What is the Zener voltage tolerance for JANTXV1N4115C-1?
JANTXV1N4115C-1 has a nominal Zener voltage of 22.0 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tighter tolerance enables higher-accuracy voltage references compared to standard 5% parts like JANTXV1N4115-1, and is verified under JEDEC test conditions at 250 mA Zener test current.
Is JANTXV1N4115C-1 RoHS compliant?
No, JANTXV1N4115C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for MIL-qualified JANTXV-level devices. The JANTXV1N4115C-1 uses traditional tin-lead plating on its axial leads to meet MIL-STD-750 solderability requirements.
What is the maximum reverse leakage current for JANTXV1N4115C-1?
The maximum reverse leakage current for JANTXV1N4115C-1 is 0.01 µA at 16.8 V (76% of nominal Zener voltage), as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance bias networks in precision analog circuits where leakage-induced errors must be minimized.
Does JANTXV1N4115C-1 have radiation-hardened characteristics?
Yes, JANTXV1N4115C-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 glass package provide tolerance to total ionizing dose (TID) and single-event effects (SEE), making it suitable for use in space and nuclear environments where radiation-induced parameter shift must be avoided.
What is the thermal resistance junction-to-lead for JANTXV1N4115C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4115C-1 is 250 °C/W when measured at 10 mm lead length from the package body, per the Maximum Ratings table. This value informs thermal design when mounting the DO-35 device on heatsinks or copper pours, and supports derating calculations for operation above 25 °C ambient temperature.
