Product details
Overview
JANS1N4130D-1/TR from Microsemi is a 500 mW, 68 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 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 JANS1N4130D-1/TR datasheet, JANS1N4130D-1/TR pinout, JANS1N4130D-1/TR application, or JANS1N4130D-1/TR equivalent, key selection criteria include military-grade reliability qualification (JANS), tight 1% Zener voltage tolerance, low noise density (1 µV/√Hz), hermetic DO-35 packaging, and radiation-hardened performance per MicroNote 050.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with cathode band marking polarity. Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock, critical for space-qualified systems. The device exhibits minimal capacitance (<1 pF typical at 68 V) and non-sensitive ESD behavior per MIL-STD-750 Method 1020.
Thermal resistance is specified as 250 °C/W junction-to-lead (at 10 mm lead length) and 300 °C/W junction-to-ambient on FR4 board. Power derating begins linearly at 50 °C ambient, reaching zero dissipation at 175 °C - consistent with MIL-PRF-19500/435 thermal requirements for JANS-level parts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±1% at 250 mA - enables precise reference generation in avionics power monitors and radiation-tolerant voltage supervisors. |
| Power Rating | 500 mW at 25 °C - supports continuous regulation in low-power analog signal chains without forced cooling. |
| Dynamic Impedance ZZT | 700 Ω at IZT = 250 mA - ensures stable output under varying load conditions in precision bias networks. |
| Reverse Leakage IR | ≤0.01 µA at VR = 54.4 V - minimizes quiescent current drain in battery-backed spacecraft subsystems. |
| Noise Density ND | 1 µV/√Hz at 68 V - critical for low-noise reference design in telemetry front-ends and sensor excitation circuits. |
| Temp Coefficient αVZ | +0.100 %/°C - predictable positive drift allows accurate compensation in wide-temperature-range flight control electronics. |
| Junction Temp Range | –65 to +175 °C - validated for operation in orbital vacuum and re-entry thermal extremes. |

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; RoHS-compliant matte tin plating. | Designed for automated SMT assembly; lacks JANS qualification; rated only to JANTXV level. | Select when board space constraints require SMT and radiation hardness is not required. |
| JAN1N4130D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (not JANS); lower screening rigor and no radiation hardness validation. | Approved for ground-based military systems but excluded from flight-critical satellite programs per NASA-SSP-30237. | Select only for terrestrial defense electronics where full JANS screening and TID testing are unnecessary. |
Compared with JANS1N4130D-1/TR, 1N4130US-1 trades JANS qualification and axial mounting for SMT compatibility, while JAN1N4130D-1 reduces cost and test burden at the expense of radiation tolerance and extended temperature validation - making JANS1N4130D-1/TR the sole choice for space-qualified voltage references requiring guaranteed 100 krad(Si) survivability.

FAQ
What is the Zener voltage tolerance of JANS1N4130D-1/TR?
JANS1N4130D-1/TR has a nominal Zener voltage of 68 V with a tight ±1% tolerance, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is verified under thermal equilibrium at 25 °C and applies across the full qualified temperature range of –65 to +175 °C, supporting precision reference applications in flight hardware where calibration margins are constrained.
Is JANS1N4130D-1/TR qualified for space applications?
Yes, JANS1N4130D-1/TR is qualified to JANS level per MIL-PRF-19500/435, which includes full Class S (space) screening per MIL-STD-883. It is validated for radiation hardness up to 100 krad(Si) per Microsemi MicroNote 050 and approved for use in satellite power systems, onboard computers, and telemetry subsystems requiring long-term parametric stability in orbit.
What does the "TR" suffix mean in JANS1N4130D-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANS1N4130D-1/TR is supplied in reels containing standard quantities defined by Microsemi's packaging specification, with full traceability back to wafer lot and screening batch - essential for aerospace manufacturing compliance and FAI documentation.
How does the noise performance of JANS1N4130D-1/TR compare to lower-voltage Zeners?
JANS1N4130D-1/TR exhibits 1 µV/√Hz noise density at 68 V, consistent with Microsemi's specification that noise falls rapidly below 6.8 V and reaches this minimum at higher voltages. This ultra-low noise enables direct use in high-resolution ADC references and RF bias networks without additional filtering, unlike 3.3 V or 5.1 V Zeners which may exhibit >10× higher noise density.
Can JANS1N4130D-1/TR replace commercial-grade 1N4130 diodes in existing designs?
JANS1N4130D-1/TR is not a drop-in replacement for commercial 1N4130 variants due to stricter screening, different qualification levels, and tighter process controls. While electrically identical, its JANS qualification mandates updated reliability documentation, radiation test reports, and lot traceability - requiring formal change control and requalification per DO-254/DO-178 for certified avionics systems using JANS1N4130D-1/TR.
