Product details
Overview
JANS1N4130-1/TR from Microsemi is a 500 mW, 68 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial 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, 0.01 µA max reverse leakage at 51.7 V, and +0.100 %/°C temperature coefficient.
For engineers reviewing the JANS1N4130-1/TR datasheet, JANS1N4130-1/TR pinout, JANS1N4130-1/TR application, or JANS1N4130-1/TR equivalent, key selection criteria include Zener voltage accuracy under thermal stress, radiation hardness, low-noise operation in precision references, and compliance with military screening requirements for extended temperature range and long-term stability.
Technical Context
This device operates as a two-terminal shunt voltage regulator, biased in reverse breakdown to maintain a stable 68 V reference across its terminals over wide current (1–40 mA) and temperature (−65 °C to +175 °C) ranges. Its internal metallurgical bond ensures mechanical robustness and low parameter drift under thermal cycling and vibration.
The JANS1N4130-1/TR exhibits 5.6 mA maximum Zener current (IZM) at full rated power, 40 µV/√Hz noise density at ≥6.8 V, and minimal capacitance (~1.5 pF typical), making it suitable for low-noise analog references and high-stability biasing in RF and instrumentation circuits where ESD immunity and radiation tolerance are critical.

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 nominal Zener, but in DO-213AA surface-mount package; no JANS qualification | Limited to commercial-grade industrial PCBs without hermetic sealing or radiation requirements | Select when board space constraints prohibit axial leads and military screening is unnecessary |
| JANTXV1N4130-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (less rigorous screening than JANS) | Suitable for high-reliability ground-based systems where full JANS radiation and life testing not mandated | Choose for cost-sensitive aerospace subsystems requiring MIL-PRF-19500 compliance but not space-qualified screening |
Compared with JANS1N4130-1/TR, the JANTXV1N4130-1 offers identical regulation performance with reduced screening rigor and lower cost, while the 1N4130US-1 trades hermeticity and reliability for SMT compatibility-neither is pin-compatible due to differing packages, and both require layout revision if substituted.

FAQ
What is the Zener voltage tolerance and test condition for JANS1N4130-1/TR?
The JANS1N4130-1/TR has a nominal Zener voltage of 68 V with ±5% tolerance, measured at 250 mA Zener test current (IZT) and 25 °C ambient temperature under thermal equilibrium conditions. This tolerance reflects the initial calibration spread before screening and does not include additional drift from temperature or aging effects.
Is JANS1N4130-1/TR RoHS compliant?
No, JANS1N4130-1/TR is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0245-2, RoHS-compliant versions (suffix e3) are available only for commercial-grade parts; JANS-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum Zener current IZM for JANS1N4130-1/TR?
The maximum Zener current IZM for JANS1N4130-1/TR is 5.6 mA, derived from its 500 mW power rating and 68 V Zener voltage (P = V × I → I = 0.5 W / 68 V ≈ 7.4 mA), adjusted downward to account for thermal resistance and safe operating area limits per the datasheet's absolute maximum ratings table.
Does JANS1N4130-1/TR have radiation hardness certification?
Yes, JANS1N4130-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. It is qualified to withstand total ionizing dose (TID) levels relevant to low-earth orbit and terrestrial nuclear environments without functional degradation or significant parametric shift, supporting use in unhardened satellite payloads and reactor instrumentation.
What packaging option does JANS1N4130-1/TR use and how is polarity marked?
JANS1N4130-1/TR uses the DO-35 (DO-204AH) hermetically sealed axial-glass package. Polarity is marked by a cathode band; the diode must be operated with the banded end positive relative to the anode to achieve Zener regulation, as confirmed in the Mechanical and Packaging section of the official datasheet.
