Product details
Overview
JANTX1N4103C-1 from Microsemi is a 500 mW, 9.1 V ±2% tolerance Zener diode in DO-35 glass axial package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4103C-1 datasheet, JANTX1N4103C-1 pinout, JANTX1N4103C-1 application, or JANTX1N4103C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics across wide temperature ranges. Its low noise density (1 µV/√Hz) and tight 2% voltage tolerance support reference stability in analog measurement circuits and regulated bias networks.
The JANTX1N4103C-1 exhibits a positive temperature coefficient of +0.080 %/°C and maintains regulation down to 0.5 µA reverse current at VR = 7.0 V, enabling use in low-power sensing and standby-mode voltage references where leakage sensitivity matters.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 9.1 V ±2% at 250 mA test current - ensures precise reference accuracy under nominal regulation load |
| Power Dissipation | 500 mW at TL = 25 °C, linearly derated to zero at 175 °C - defines maximum safe continuous power in lead-mounted configurations |
| Dynamic Impedance (ZZT) | 200 Ω at 250 mA - determines output voltage variation under changing load current |
| Noise Density | 1 µV/√Hz at 250 mA - critical for low-noise analog references and precision instrumentation |
| Reverse Leakage (IR) | 0.5 µA at 7.0 V - enables stable operation in ultra-low-current bias networks |
| Temp. Coefficient (αVZ) | +0.080 %/°C - quantifies voltage drift over operating temperature range |
| Junction Temp. Range | –65 °C to +175 °C - supports deployment in extreme-environment avionics and space-qualified systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Used where PCB real estate is constrained and reflow assembly is required | Select when transitioning from through-hole to SMT production without changing regulation performance |
| JAN1N4103C-1 | Identical electrical and mechanical specs but qualified only to JAN level (lower screening than JANTX) | Suitable for non-critical subsystems where full JANTX burn-in and life-test requirements are waived | Choose for cost-sensitive programs where MIL-PRF-19500/435 compliance is required but JANTX-level reliability is not mandated |
Compared with JANTX1N4103C-1, the 1N4103US-1 offers identical regulation performance in a space-saving surface-mount form factor, while the JAN1N4103C-1 provides the same Zener characteristics at reduced qualification rigor-enabling trade-offs between reliability assurance, board layout, and procurement cost.

FAQ
What is the Zener voltage tolerance of JANTX1N4103C-1?
JANTX1N4103C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 9.1 V Zener voltage is guaranteed to fall between 8.918 V and 9.282 V when tested at 250 mA under standard conditions. The tolerance is verified per MIL-PRF-19500/435 screening for JANTX-level devices.
Is JANTX1N4103C-1 RoHS compliant?
No, JANTX1N4103C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JANTX, JANTXV, or JANS military-qualified parts. The JANTX1N4103C-1 uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum junction temperature rating for JANTX1N4103C-1?
JANTX1N4103C-1 has a maximum junction and storage temperature rating of +175 °C, with a minimum of –65 °C. This wide range supports operation in extreme environments such as engine-mounted avionics or desert-deployed defense electronics, and the device must be thermally derated linearly from 500 mW starting at 50 °C lead temperature.
How does the noise performance of JANTX1N4103C-1 compare to lower-voltage Zeners in the same family?
JANTX1N4103C-1 delivers 1 µV/√Hz noise density at 250 mA, consistent with other ≥6.8 V devices in the 1N4099–1N4135 series. Lower-voltage Zeners (e.g., 1N4614-1 at 1.8 V) exhibit higher noise (up to 40 µV/√Hz), making JANTX1N4103C-1 preferable for low-noise reference designs where signal integrity is critical.
Can JANTX1N4103C-1 be used in surface-mount assemblies?
No, JANTX1N4103C-1 is packaged exclusively in the axial-leaded DO-35 (DO-204AH) glass case and is intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the 1N4103US-1 in DO-213AA package-same electrical specs but different mechanical form factor and qualification level.
