Product details
Overview
JANTXV1N4103C-1 from Microsemi is a 500 mW, 9.1 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4103C-1 datasheet, JANTXV1N4103C-1 pinout, JANTXV1N4103C-1 application, or JANTXV1N4103C-1 equivalent, key selection criteria include its 9.1 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.5 µA reverse leakage at 7.0 V, ±2% voltage tolerance, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with Zener voltage specified at IZT = 250 mA and characterized for stable regulation across wide current (1–40 mA) and temperature (-65 °C to +175 °C) ranges. Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical at low voltages) and radiation hardness per Microsemi MicroNote 050.
It exhibits a positive temperature coefficient of +0.080 %/°C, enabling predictable voltage drift in thermal cycling environments. The DO-35 hermetically sealed glass package provides ESD immunity per MIL-STD-750 Method 1020 and minimal capacitance (~4 pF at 9.1 V), supporting stable performance in analog reference and feedback circuits.

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 surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated placement is available |
| JANTXV1N4103D-1 | Identical except ±1% Zener tolerance (D suffix); higher test cost and longer lead time | Used only where <±0.5% total reference error is mandated (e.g., metrology calibrators) | Select only if ±2% tolerance of JANTXV1N4103C-1 fails system-level accuracy budget |
Compared with JANTXV1N4103C-1, the US-1 variant trades axial mounting flexibility for SMT compatibility, while the D-1 variant adds tighter tolerance at the cost of availability and cost-neither offers pin-to-pin replacement without layout or sourcing changes.

FAQ
What is the Zener voltage tolerance of JANTXV1N4103C-1?
JANTXV1N4103C-1 has a nominal Zener voltage of 9.1 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and remains stable across the full -65 °C to +175 °C junction temperature range due to its metallurgical bond construction.
Is JANTXV1N4103C-1 suitable for space applications?
Yes, JANTXV1N4103C-1 is qualified to MIL-PRF-19500/435 JANTXV level and documented as inherently radiation hard per Microsemi MicroNote 050. It is routinely used in LEO satellite power subsystems where total ionizing dose (TID) and single-event effects (SEE) resilience are required, provided derating and screening per SMD 5962-00-001 are applied.
What is the maximum reverse leakage current for JANTXV1N4103C-1?
The maximum reverse leakage current (IR) for JANTXV1N4103C-1 is 0.5 µA at VR = 7.0 V, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This low leakage supports ultra-low-power standby modes in battery-operated defense electronics without compromising regulation accuracy.
Does JANTXV1N4103C-1 require heatsinking in normal operation?
No, JANTXV1N4103C-1 does not require external heatsinking when operated within its 500 mW rated power dissipation at 25 °C ambient. Its thermal resistance junction-to-lead is 250 °C/W with 10 mm lead length, allowing safe operation up to ~125 °C case temperature before linear derating begins at 50 °C ambient per Figure 2.
Can JANTXV1N4103C-1 be substituted with a commercial-grade 1N4103-1?
No-JANTXV1N4103C-1 is not a drop-in substitute for commercial 1N4103-1. It undergoes full MIL-PRF-19500/435 JANTXV screening including burn-in, temperature cycling, and lot acceptance testing. Commercial versions lack radiation hardness, guaranteed -65 °C operation, and traceable lot documentation required for defense/aerospace BOMs.
