Product details
Overview
JANTXV1N4101D-1/TR from Microsemi is a 1% tolerance, 8.2 V, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supply circuits.
For engineers reviewing the JANTXV1N4101D-1/TR datasheet, JANTXV1N4101D-1/TR pinout, JANTXV1N4101D-1/TR application, or JANTXV1N4101D-1/TR equivalent, this part delivers precise low-noise voltage reference with ±1% initial tolerance, -65°C to +175°C operating range, and metallurgically bonded construction for stable regulation under thermal stress and radiation exposure.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 8.2 V reference across load current variations from 0.5 µA to 6.3 mA, with dynamic impedance of 200 Ω at 250 mA test current and temperature coefficient of +0.070 %/°C - enabling predictable drift compensation in precision analog circuits.
Its hermetically sealed DO-35 glass package provides intrinsic radiation hardness and ESD immunity per MIL-STD-750 Method 1020, while the internal metallurgical bond ensures long-term parameter stability under thermal cycling and high-vibration environments typical of avionics and space-grade systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.2 V ±1% at 250 mA - ensures tight reference accuracy for calibration and feedback loops. |
| Power Dissipation | 500 mW at 25°C, derated linearly to zero at 175°C - supports operation in high-temperature enclosures without forced cooling. |
| Dynamic Impedance (ZZT) | 200 Ω at IZT = 250 mA - minimizes output voltage variation under changing load currents. |
| Reverse Leakage (IR) | ≤0.5 µA at 6.3 V - guarantees low quiescent current in battery-backed or ultra-low-power bias networks. |
| Temperature Coefficient | +0.070 %/°C - enables predictable, monotonic drift for temperature-compensated reference designs. |
| Noise Density | 1 µV/√Hz (typical) - critical for low-noise analog front-ends and precision ADC reference buffers. |
| Junction Temperature Range | -65°C to +175°C - validated for extended-range operation in missile guidance, satellite power, and downhole electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package: hermetically sealed, cathode indicated by single black band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026; weight ≈0.2 g.

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, 1% tolerance, but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow assembly is required instead of through-hole mounting. | Select when transitioning from through-hole to SMT production or when minimizing PCB footprint is critical. |
| JANTXV1N4101C-1/TR | Identical 8.2 V rating and JANTXV qualification, but ±2% tolerance (C suffix) instead of ±1% (D suffix). | Acceptable where tighter tolerance is not required for system-level accuracy budget. | Choose for cost-sensitive programs where 2% tolerance meets functional spec and reduces procurement cost. |
Compared with JANTXV1N4101D-1/TR, the 1N4101US-1 offers identical electrical performance in a smaller footprint but lacks axial-lead mechanical robustness, while JANTXV1N4101C-1/TR trades 1% tolerance for lower unit cost without sacrificing reliability or temperature range.

Its metallurgically bonded DO-35 construction and hermetic glass seal make it appropriate for low-earth orbit and deep-space missions where TID and SEE resilience are required.
What is the maximum reverse leakage current for JANTXV1N4101D-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4101D-1/TR is 0.5 µA at 6.3 V reverse voltage and 25°C, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This low leakage supports ultra-low-power bias networks in battery-operated systems.
Does JANTXV1N4101D-1/TR require derating above 25°C?
Yes - JANTXV1N4101D-1/TR must be linearly derated from 500 mW starting at 25°C ambient, reaching zero power dissipation at +175°C. Derating follows a slope of -3.57 mW/°C, as defined in Note 2 on page 1 of the datasheet and illustrated in Figure 2 (Power Derating Curve).
What does the "TR" suffix indicate in JANTXV1N4101D-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTXV1N4101D-1/TR is supplied in reels for high-volume manufacturing, with plating compliant to MIL-STD-750 Method 2026 for reliable solderability.
