Product details
Overview
JANTXV1N4101-1/TR from Microsemi is a 500 mW, 8.2 V ±5% 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. It delivers stable reference voltage at 250 mA test current, with dynamic impedance ≤200 Ω, max reverse leakage ≤0.5 µA at 6.3 V, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANTXV1N4101-1/TR datasheet, JANTXV1N4101-1/TR pinout, JANTXV1N4101-1/TR application, or JANTXV1N4101-1/TR equivalent, key selection criteria include its military-grade qualification, low noise density (≤1 µV/√Hz below 6.8 V), hermetic glass packaging, thermal resistance of 250 °C/W (junction-to-lead), and compatibility with lead-free soldering per MIL-STD-750 method 2026.
Technical Context
This device functions as a precision shunt voltage regulator, operating in reverse breakdown with cathode-banded polarity. Its metallurgical bond construction ensures low long-term drift and radiation hardness per MicroNote 050, while the DO-35 glass package provides hermetic sealing and ESD immunity per MIL-STD-750 method 1020.
It exhibits a positive temperature coefficient of +0.070 %/°C, enabling predictable voltage shift over temperature, and maintains ≤200 Ω dynamic impedance at 250 mA Zener test current - critical for low-noise analog references and power supply feedback loops where stability under varying load is required.
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 electrical specs, but in surface-mount DO-213AA package (no leads); 0.5 W rating maintained | Requires SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and reflow capability exists |
| JANTXV1N4101US-1/TR | Identical Zener parameters and JANTXV qualification, but in DO-213AA package with tape-and-reel delivery | Lacks axial leads; not mechanically interchangeable; thermal path differs (RθJA higher than DO-35) | Choose only for automated production where DO-35 lead forming is impractical |
Compared with JANTXV1N4101-1/TR, the DO-213AA alternatives offer identical regulation performance but trade axial-mount robustness and lower thermal resistance for compactness and SMT compatibility - making them suitable for volume production but less ideal for high-shock environments or manual integration.

FAQ
What is the Zener voltage tolerance for JANTXV1N4101-1/TR?
JANTXV1N4101-1/TR has a nominal Zener voltage of 8.2 V with a ±5% tolerance, as defined by the "blank" suffix in its nomenclature per MIL-PRF-19500/435. This tolerance applies at 250 mA test current and 25 °C ambient, and is verified during JANTXV-level screening. The device does not support tighter 2% (C) or 1% (D) tolerances - those require different part numbers such as JANTXV1N4101C-1/TR.
Is JANTXV1N4101-1/TR compatible with lead-free soldering processes?
Yes, JANTXV1N4101-1/TR is compatible with lead-free soldering: its terminals are plated with RoHS-compliant annealed matte-tin (per commercial-grade specification), and it withstands 260 °C for 10 seconds per MIL-STD-750 method 2026. While the JANTXV version itself is not RoHS-compliant (e3 suffix reserved for commercial grade), its matte-tin plating ensures reliable wetting and joint integrity in Pb-free reflow profiles.
What is the maximum reverse leakage current for JANTXV1N4101-1/TR?
The maximum reverse leakage current for JANTXV1N4101-1/TR is 0.5 µA measured at VR = 6.3 V (80% of nominal VZ), per the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value is guaranteed across the full –65 °C to +175 °C junction temperature range and is confirmed during JANTXV-level environmental stress screening.
Does JANTXV1N4101-1/TR have radiation hardness certification?
Yes, JANTXV1N4101-1/TR exhibits inherent radiation hardness due to its metallurgically bonded construction and glass package, as documented in Microsemi MicroNote 050. While not individually tested to specific TID or SEE levels, the device family is widely deployed in radiation-prone environments (e.g., satellites, nuclear instrumentation), and its JANTXV qualification includes radiation lot acceptance testing per MIL-PRF-19500/435 Annex G.
Can JANTXV1N4101-1/TR be used in surface-mount designs?
No - JANTXV1N4101-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider JANTXV1N4101US-1/TR (DO-213AA) or 1N4101US-1 (commercial DO-213AA), which share identical electrical specifications but differ in package, thermal resistance, and mechanical mounting requirements.
