Product details
Overview
JANTX1N4130D-1/TR from Microsemi is a 500 mW, 68 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4130D-1/TR datasheet, JANTX1N4130D-1/TR pinout, JANTX1N4130D-1/TR application, or JANTX1N4130D-1/TR equivalent, key selection criteria include its 1% Zener voltage tolerance, 700 Ω dynamic impedance at 250 mA, 40 µV/√Hz noise density, and operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 68 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient of +0.100 %/°C and low leakage (<10 nA at 54.4 V). Its metallurgical bond construction ensures stable regulation under thermal cycling and radiation exposure.
The DO-35 hermetically sealed glass package enables reliable axial mounting in high-vibration environments, while its 250 °C/W junction-to-lead thermal resistance supports stable power dissipation up to 500 mW at lead temperature ≤50 °C, derating linearly to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±1% at 250 mA - ensures tight output regulation in reference circuits requiring <±0.68 V deviation. |
| Power Dissipation | 500 mW at TC = 25 °C - supports continuous regulation in compact, unheatsinked designs with linear derating above 50 °C. |
| Dynamic Impedance ZZT | 700 Ω max at 250 mA - limits output voltage variation under load transients; critical for low-noise analog references. |
| Noise Density ND | 40 µV/√Hz at 68 V - defines minimum achievable ripple in precision voltage references; lower than most <10 V Zeners. |
| Reverse Leakage IR | ≤10 nA at VR = 54.4 V - minimizes error current in high-impedance bias networks and sensor excitation circuits. |
| Temp Coefficient αVZ | +0.100 %/°C - enables predictable drift compensation in temperature-stable reference designs. |
| Junction Temp Range | –65 °C to +175 °C - qualifies for extended-range military and downhole industrial applications without derating. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026. Body diameter 1.42–2.29 mm, overall length 3.56–5.08 mm, lead length ≥25.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-impedance return; must handle full Zener current during regulation. |
| Cathode (banded end) | Regulated output node | Provides stable 68 V reference; polarity must be observed-reverse connection causes forward conduction and failure. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Guarantees screening, testing, and traceability for aerospace-grade reliability and lot-level documentation. |
| 1% Zener voltage tolerance | Reduces need for post-assembly trimming in precision reference designs, lowering calibration cost and time. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and sustained high-power operation. |
| Low 40 µV/√Hz noise density | Enables use in ultra-low-noise analog front-ends where standard Zeners introduce unacceptable signal corruption. |
| Hermetic glass DO-35 package | Prevents moisture ingress and parameter shift over decades-critical for long-life satellite and avionics systems. |
Applications
| Avionics Power Reference | Satellite DC-DC Converter Feedback |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4130US-1 | Same 68 V, 1% spec, but in DO-213AA surface-mount package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and automated placement is available. |
| JANS1N4130D-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500 level) with full lot traceability and extended screening. | Required for mission-critical flight hardware; adds cost and longer lead times vs. JANTX grade. | Select only when JANS-level reliability documentation and radiation assurance are mandated. |
Compared with 1N4130US-1 and JANS1N4130D-1, the JANTX1N4130D-1/TR offers optimal balance of MIL-qualified reliability, axial-leaded mechanical robustness, and cost-effective procurement for avionics and defense subsystems not requiring full JANS certification.

FAQ
What does the "D" suffix in JANTX1N4130D-1/TR indicate?
The "D" suffix in JANTX1N4130D-1/TR specifies ±1% Zener voltage tolerance, per the Microsemi part nomenclature guide. This tighter tolerance enables higher-accuracy voltage references without post-production calibration. JANTX1N4130D-1/TR delivers 68 V ±0.68 V at 250 mA, distinguishing it from the standard ±5% "blank" version.
Is JANTX1N4130D-1/TR compatible with lead-free soldering processes?
JANTX1N4130D-1/TR features RoHS-compliant matte-tin plating (e3 suffix variant), rated for 10-second exposure to 260 °C per MIL-STD-750 method 2026. The DO-35 glass body withstands standard lead-free reflow profiles, though hand-soldering requires controlled iron temperature to avoid thermal shock cracking.
How does the noise performance of JANTX1N4130D-1/TR compare to lower-voltage Zeners?
JANTX1N4130D-1/TR exhibits 40 µV/√Hz noise density at 68 V, consistent with Microsemi's specification for devices ≥6.8 V. While lower-voltage Zeners (e.g., 5.1 V) show sub-1 µV/√Hz, JANTX1N4130D-1/TR's noise remains exceptionally low for its voltage class-critical for high-voltage precision references where noise scales with VZ.
Can JANTX1N4130D-1/TR be used in series or parallel configurations?
JANTX1N4130D-1/TR is not recommended for parallel operation due to mismatched dynamic impedances causing current hogging. In series, it can generate higher composite reference voltages (e.g., two units = 136 V), but thermal coupling must be managed to avoid unequal power sharing and premature failure.
What is the maximum allowable reverse voltage before breakdown for JANTX1N4130D-1/TR?
JANTX1N4130D-1/TR begins regulating at its nominal Zener voltage of 68 V, with breakdown knee occurring between 67.3 V and 68.7 V (1% tolerance band). Reverse voltage below 54.4 V yields ≤10 nA leakage; operation above 68.7 V at rated current maintains regulation, but exceeding 500 mW dissipation risks thermal runaway.
