Product details
Overview
JANS1N4130C-1/TR from Microsemi is a 500 mW, 68 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation with 700 Ω dynamic impedance at 250 mA test current, 5.6 mA maximum Zener current, and +0.100 %/°C temperature coefficient.
For engineers reviewing the JANS1N4130C-1/TR datasheet, JANS1N4130C-1/TR pinout, JANS1N4130C-1/TR application, or JANS1N4130C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), radiation hardness, hermetic glass packaging, noise density (≤1 μV/√Hz), and MIL-qualified thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures low leakage and stable long-term Zener voltage under thermal cycling and radiation exposure.
It exhibits minimal capacitance (typical <2 pF at 68 V), low noise density (<1 μV/√Hz below 6.8 V), and non-ESD-sensitive behavior per MIL-STD-750 Method 1020 - enabling use in low-noise reference and hardened analog signal conditioning circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±2% at 250 mA - enables precise 68 V rail clamping or reference generation with tight initial accuracy |
| Power Dissipation | 500 mW at +25 °C, linearly derated to zero at +175 °C - supports operation in high-temp avionics enclosures |
| Dynamic Impedance ZZT | 700 Ω at IZT = 250 mA - limits output voltage variation under load current changes |
| Reverse Leakage IR | ≤0.01 µA at VR = 54.4 V - ensures negligible standby current in battery-backed systems |
| Temp Coefficient αVZ | +0.100 %/°C - predictable positive drift simplifies temperature-compensated reference design |

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 ±2% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated placement is available |
| JANTXV1N4130C-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS); lower screening rigor | Approved for high-reliability ground systems but not spaceflight or nuclear-hardened deployments | Select when full JANS screening is not mandated by program requirements |
Compared with JANS1N4130C-1/TR, the 1N4130US-1 offers footprint reduction at the cost of mechanical mounting flexibility, while JANTXV1N4130C-1 provides identical performance with reduced qualification overhead - enabling trade-offs between mission assurance level and procurement lead time.

FAQ
What is the Zener voltage tolerance of JANS1N4130C-1/TR?
JANS1N4130C-1/TR has a nominal Zener voltage of 68 V with a tolerance of ±2%, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed under standard test conditions at 25 °C with 250 mA Zener test current and applies across the full qualified temperature range when derated per MIL-PRF-19500/435 requirements.
Is JANS1N4130C-1/TR RoHS compliant?
No, JANS1N4130C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4130C-1e3); JANS-level parts retain legacy tin-lead plating per MIL-STD-750 Method 2026 to ensure solderability and reliability in high-reliability solder processes used in aerospace and defense manufacturing.
What does the "TR" suffix mean in JANS1N4130C-1/TR?
The "TR" suffix in JANS1N4130C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and requires no special ordering notation beyond the suffix; reel quantities and orientation follow Microsemi's standard DO-35 carrier tape specifications.
How is the temperature coefficient of JANS1N4130C-1/TR specified?
JANS1N4130C-1/TR has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by 0.068 V per 1 °C rise in junction temperature. This value is measured and guaranteed per MIL-PRF-19500/435 test methods and is consistent across the JANS-qualified population, supporting predictable thermal compensation in reference designs.
Can JANS1N4130C-1/TR be used in radiation-intensive environments?
Yes, JANS1N4130C-1/TR is inherently radiation-hardened due to its metallurgically bonded structure and hermetic glass package. Microsemi MicroNote 050 documents its performance under total ionizing dose (TID) exceeding 100 krad(Si), making it suitable for satellite, nuclear instrumentation, and strategic defense systems where parametric stability under irradiation is mandatory.
