Product details
Overview
JANS1N4134-1/TR from Microsemi is a 500 mW, 91 V, ±5% 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 at 250 mA test current with 1200 Ω dynamic impedance, 40 µV/√Hz noise density, and operates across –65 °C to +175 °C junction temperature.
For engineers reviewing the JANS1N4134-1/TR datasheet, JANS1N4134-1/TR pinout, JANS1N4134-1/TR application, or JANS1N4134-1/TR equivalent, key selection criteria include its JANS-level radiation-hardened qualification, low-noise performance above 6.8 V, hermetic DO-35 packaging, and precise 91 V Zener voltage under military-grade thermal and reliability constraints.
Technical Context
This device functions as a precision shunt voltage regulator in feedback loops, reference supplies, and overvoltage protection circuits where long-term stability under extreme environmental stress is required. Its internal metallurgical bond ensures mechanical robustness and low parameter drift across thermal cycling and radiation exposure.
The JANS1N4134-1/TR exhibits a +0.100 %/°C temperature coefficient and maintains ≤0.01 µA reverse leakage at 73 V, enabling predictable regulation in high-temperature avionics power rails and analog sensor references. Its 250 °C/W junction-to-lead thermal resistance supports reliable operation with minimal heatsinking in constrained chassis-mount configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4134US-1 | Same 91 V Zener, but in surface-mount DO-213AA package; lacks JANS qualification; RoHS-compliant only | Used in commercial PCBs with automated assembly; not approved for flight hardware or radiation environments | Select when cost, board space, or reflow compatibility outweigh military reliability requirements |
| JANTXV1N4134-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS); lower radiation tolerance and screening depth | Approved for ground-support equipment and non-flight avionics; excluded from spacecraft and strategic weapon systems | Select when full JANS qualification is unnecessary but MIL-PRF-19500 compliance is mandatory |
Compared with JANS1N4134-1/TR, the 1N4134US-1 offers SMT compatibility at the expense of radiation hardness and hermeticity, while JANTXV1N4134-1 reduces cost and test burden but excludes use in mission-critical space or nuclear applications requiring JANS-level assurance.

FAQ
What is the Zener voltage tolerance of JANS1N4134-1/TR?
The JANS1N4134-1/TR has a nominal Zener voltage of 91 V with a ±5% tolerance, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies at 250 mA test current and 25 °C ambient, and is consistent across all JANS-qualified units per MIL-PRF-19500/435 screening requirements.
Is JANS1N4134-1/TR radiation hardened?
Yes, JANS1N4134-1/TR is inherently radiation hard per Microsemi MicroNote 050 and qualified to JANS level under MIL-PRF-19500/435, which includes total ionizing dose (TID) testing and burn-in screening appropriate for spaceflight and nuclear environments. Its metallurgically bonded structure contributes directly to this hardness.
What is the maximum reverse leakage current for JANS1N4134-1/TR?
The maximum reverse leakage current (IR) for JANS1N4134-1/TR is 0.01 µA at 73 V, as stated in the Electrical Characteristics table. This value is measured at 25 °C and reflects the device's ultra-low leakage essential for high-impedance reference applications.
Does JANS1N4134-1/TR have a RoHS-compliant version?
No - JANS1N4134-1/TR is a JANS-level military specification part and is not offered in RoHS-compliant form. RoHS compliance (e.g., matte-tin plating) is available only on commercial-grade versions such as 1N4134-1e3, per the nomenclature table on page 2 of the datasheet.
What package type does JANS1N4134-1/TR use?
JANS1N4134-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package, as confirmed in the Mechanical and Packaging section (page 2) and Package Dimensions (page 5) of T4-LDS-0245-2. The "TR" suffix indicates tape-and-reel packaging per EIA-296.
