Product details
Overview
JANTXV1N4101C-1 from Microsemi is a 500 mW, 8.2 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4101C-1 datasheet, JANTXV1N4101C-1 pinout, JANTXV1N4101C-1 application, or JANTXV1N4101C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω @ 250 mA), noise density (40 µV/√Hz), temperature coefficient (+0.070 %/°C), and military-grade thermal derating (0 W at 175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 8.2 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and stable regulation across -65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The JANTXV1N4101C-1 delivers low-noise performance (40 µV/√Hz typical) and minimal capacitance (<2 pF), making it suitable for reference and biasing circuits where signal integrity and stability are critical. It is RoHS-compliant only in commercial versions; this JANTXV variant retains tin-lead plating per MIL-STD-750.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US-1 | Same 8.2 V ±2% spec but in DO-213AA surface-mount package; no JANTXV qualification | Used in space-constrained commercial or industrial PCBs where reflow compatibility is required | Select when board area is limited and military screening is not mandated |
| JANS1N4101C-1 | Identical electrical specs and DO-35 package, but qualified to JANS level (highest MIL-PRF-19500 reliability tier) | Required for nuclear-hardened or mission-critical launch systems where failure probability must be <10−9/hour | Select when full JANS screening, including neutron irradiation testing, is specified in program requirements |
Compared with JANTXV1N4101C-1, the 1N4101US-1 offers footprint reduction at the cost of reliability assurance, while the JANS1N4101C-1 extends screening depth without altering regulation performance-enabling trade-offs between cost, size, and assurance level.

FAQ
What is the Zener voltage tolerance of JANTXV1N4101C-1?
JANTXV1N4101C-1 has a nominal Zener voltage of 8.2 V with a tolerance of ±2%, as indicated by the "C" suffix in its nomenclature. This tolerance is verified per MIL-PRF-19500/435 screening and applies at 250 mA test current and 25 °C ambient. The tighter tolerance supports higher accuracy in closed-loop regulation and reference applications compared to standard ±5% variants.
Does JANTXV1N4101C-1 meet RoHS requirements?
No, JANTXV1N4101C-1 does not meet RoHS requirements. Per Microsemi documentation, RoHS compliance (e3 suffix) is available only on commercial-grade versions of this series. The JANTXV variant uses tin-lead plating per MIL-STD-750 method 2026 and is exempt from RoHS under military application waivers.
What is the maximum operating temperature for JANTXV1N4101C-1?
JANTXV1N4101C-1 has a junction and storage temperature range of -65 °C to +175 °C. Its power dissipation is linearly derated from 500 mW at 25 °C to zero at 175 °C, enabling reliable operation in extreme thermal environments such as engine-mounted avionics or downhole oilfield electronics.
How is polarity marked on JANTXV1N4101C-1?
JANTXV1N4101C-1 uses a cathode band marking on the glass body to indicate polarity. The banded end is the cathode and must be connected to the higher-potential side of the circuit during Zener operation. The opposite (unbanded) end is the anode and connects to system ground or the lower-potential node.
What is the dynamic impedance of JANTXV1N4101C-1 and why does it matter?
JANTXV1N4101C-1 has a maximum dynamic impedance (ZZT) of 200 Ω at 250 mA test current. This value reflects how much the Zener voltage changes under small-signal AC load variations; lower impedance improves regulation stability during transient load shifts, especially in feedback networks of switching regulators and precision references.
