Product details
Overview
JANTX1N4130-1/TR from Microsemi is a 500 mW, 68 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation. It delivers 51.7 mA maximum Zener current at 25 °C, exhibits 700 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANTX1N4130-1/TR datasheet, JANTX1N4130-1/TR pinout, JANTX1N4130-1/TR application, or JANTX1N4130-1/TR equivalent, key selection criteria include Zener voltage stability under thermal stress, low noise density (≤1 μV/√Hz below 6.8 V), radiation hardness, and compliance with military reliability screening levels.
Technical Context
This device functions as a precision shunt voltage regulator in high-reliability analog power supply and reference circuits. Its metallurgical bond construction ensures stable breakdown characteristics and low long-term drift, while its hermetically sealed DO-35 glass package supports operation in harsh environments including aerospace and defense systems.
The JANTX1N4130-1/TR is specified for 68 V nominal Zener voltage at 250 mA test current, with ±5% tolerance, +0.100 %/°C temperature coefficient, and 0.01 µA maximum reverse leakage at 54.4 V. It is not intended for transient suppression or ESD protection - its design focus is stable DC voltage reference generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±5% at IZT = 250 mA - defines regulated output voltage under nominal bias conditions |
| Power Dissipation | 500 mW at TL = 25 °C - sets maximum continuous DC power handling before thermal derating begins |
| Dynamic Impedance ZZT | 700 Ω at IZT = 250 mA - determines output voltage variation under load current changes |
| Reverse Leakage IR | 0.01 µA at VR = 54.4 V - indicates minimal off-state conduction, critical for low-power reference stability |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift per degree Celsius, enabling thermal error budgeting in precision designs |
| Junction Temp Range | –65 °C to +175 °C - enables deployment in extended-temperature avionics, downhole, and space-qualified systems |
| Noise Density | ≤1 µV/√Hz - ensures minimal broadband noise injection into sensitive analog signal chains and reference nodes |

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 Zener voltage and JANTX qualification, but in surface-mount DO-213AA package | Requires PCB re-layout for SMT assembly; eliminates axial lead insertion and trimming steps | Select when automated assembly, board space reduction, or vibration resistance are prioritized over through-hole serviceability |
| JANS1N4130-1 | Identical electrical specs but qualified to JANS level per MIL-PRF-19500/435 - includes additional radiation and life testing | Required for spaceflight-critical subsystems where single-event effects (SEE) immunity and 100% lot acceptance testing are mandated | Select only when mission assurance requirements exceed JANTX-level screening, such as NASA Class S or ESA ESCC 4001 |
Compared with JANTX1N4130-1/TR, the 1N4130US-1 offers identical regulation performance in a compact SMT form factor, while JANS1N4130-1 adds radiation survivability and extended lifetime validation - both require explicit qualification documentation review before substitution.

FAQ
What is the Zener voltage tolerance for JANTX1N4130-1/TR?
The JANTX1N4130-1/TR has a nominal Zener voltage of 68 V with a ±5% tolerance, as defined by JEDEC standard and verified per MIL-PRF-19500/435 screening. This tolerance applies at 250 mA test current and 25 °C ambient, and remains stable across the full –65 °C to +175 °C junction temperature range due to its metallurgical bond construction.
Is JANTX1N4130-1/TR RoHS compliant?
No, JANTX1N4130-1/TR is not RoHS compliant. The "TR" suffix denotes tape-and-reel packaging; RoHS compliance (e3 suffix) is available only on commercial-grade versions (e.g., 1N4130-1e3), not on JANTX-level military-qualified parts, which retain tin-lead plating per MIL-STD-750 method 2026 for solderability and reliability in high-reliability applications.
What is the maximum Zener current rating for JANTX1N4130-1/TR?
The JANTX1N4130-1/TR is rated for a maximum Zener current (IZM) of 51.7 mA at 25 °C lead temperature. This value is derived from its 500 mW power rating and 68 V Zener voltage (P = V × I). Current must be linearly derated above 50 °C lead temperature, reaching zero at 175 °C per the published power derating curve.
Does JANTX1N4130-1/TR have radiation hardness certification?
Yes, JANTX1N4130-1/TR is inherently radiation hard per Microsemi MicroNote 050, with demonstrated tolerance to total ionizing dose (TID) exceeding 100 krad(Si). While not individually certified for specific space missions, its metallurgically bonded structure and hermetic DO-35 package provide baseline radiation resilience required for low-earth orbit avionics where JANTX-level qualification is accepted.
Can JANTX1N4130-1/TR be used as an ESD protection device?
No, JANTX1N4130-1/TR is not designed or characterized for ESD protection. It is a precision shunt voltage regulator optimized for stable DC reference generation. Its 700 Ω dynamic impedance and 500 mW power rating are unsuited for fast transient clamping; dedicated TVS diodes like Microsemi's JANTXV1N6105A are specified for ESD and surge suppression per MIL-STD-1275 and IEC 61000-4-2.
