Product details
Overview
JANTXV1N4101D-1 from Microsemi is a 500 mW, 8.2 V ±1% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTXV1N4101D-1 datasheet, JANTXV1N4101D-1 pinout, JANTXV1N4101D-1 application, or JANTXV1N4101D-1 equivalent, key selection criteria include its 8.2 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.5 µA maximum reverse leakage at 6.3 V, ±1% voltage tolerance, and -65 °C to +175 °C operating temperature range.
Technical Context
This device operates as a two-terminal shunt voltage regulator with cathode-banded polarity, requiring forward bias of the anode relative to the banded cathode for Zener conduction. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
It delivers low-noise regulation (≤1 µV/√Hz below 6.8 V), minimal capacitance (typical <4 pF), and inherent radiation hardness per Microsemi MicroNote 050 - enabling use in space-grade analog references where long-term voltage drift and single-event effects must be minimized.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4101US-1 | Same electrical specs, but in surface-mount DO-213AA package instead of axial DO-35 | Requires SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when board space is constrained and automated placement is available |
| 1N4101UR-1 | Commercial-grade (non-mil-qualified), same 8.2 V ±1%, DO-35 package, RoHS-compliant | Lacks MIL-PRF-19500 screening; not approved for defense/aerospace BOMs | Select for cost-sensitive industrial prototypes where JANTXV qualification is unnecessary |
Compared with JANTXV1N4101D-1, the JANTXV1N4101US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-solderability, while the 1N4101UR-1 reduces cost and lead time but forfeits military-grade reliability testing and traceability.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4101D-1?
JANTXV1N4101D-1 has a nominal Zener voltage of 8.2 V with ±1% tolerance, measured at a test current of 250 mA under thermal equilibrium at 25 °C. This tight tolerance eliminates the need for external trimming in precision reference designs and ensures predictable regulation behavior across production lots.
Is JANTXV1N4101D-1 qualified to military specifications?
Yes, JANTXV1N4101D-1 is fully qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including rigorous screening for vibration, thermal shock, burn-in, and parameter verification. It carries full traceability and certification documentation required for defense and aerospace procurement.
What is the maximum power dissipation and derating behavior of JANTXV1N4101D-1?
JANTXV1N4101D-1 is rated for 500 mW average power dissipation at 25 °C lead temperature, with linear derating to zero at 175 °C. On a typical FR4 board with 4 mm² copper pads, it begins derating at 50 °C ambient, ensuring safe operation in high-temperature enclosures without forced cooling.
Does JANTXV1N4101D-1 exhibit low noise performance?
Yes, JANTXV1N4101D-1 delivers ≤1 µV/√Hz noise density at its 8.2 V Zener voltage - among the lowest in its class. This is confirmed by measurement using a 1 kHz–3 kHz bandpass filter at 250 mA test current, making it suitable for low-noise analog references in instrumentation and data acquisition systems.
What package type and marking does JANTXV1N4101D-1 use?
JANTXV1N4101D-1 uses the hermetically sealed DO-35 (DO-204AH) axial-glass package with cathode indicated by a visible band. The device is marked with its full part number "JANTXV1N4101D-1" and complies with MIL-STD-750 solderability requirements for both tin-lead and RoHS-compliant finishes.
