Product details
Overview
JAN1N4134D-1/TR from Microsemi is a 500 mW, 91 V ±1% 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 voltage regulation in aerospace and defense systems.
For engineers reviewing the JAN1N4134D-1/TR datasheet, JAN1N4134D-1/TR pinout, JAN1N4134D-1/TR application, or JAN1N4134D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass packaging, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 91 V at 250 mA test current, exhibiting dynamic impedance of 1200 Ω and maximum reverse leakage of 0.01 µA at 73 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The JAN1N4134D-1/TR is designed for operation in the Zener breakdown region with cathode-banded polarity, requiring external current limiting. Its noise density falls to 1 µV/√Hz below 6.8 V - confirmed at 91 V - and its temperature coefficient is +0.100 %/°C, enabling predictable drift compensation in analog reference circuits.

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 ±1%, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when board space is constrained and automated assembly is required |
| JANTXV1N4134D-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (not JANS); lower screening rigor | Approved for high-reliability ground-based systems but not spaceflight or nuclear environments | Select when full JANS qualification is unnecessary and cost sensitivity is higher |
Compared with JAN1N4134D-1/TR, 1N4134US-1 offers footprint reduction at the expense of mechanical robustness and lead-forming flexibility, while JANTXV1N4134D-1 provides identical form-fit-function with relaxed screening - enabling trade-offs between mission assurance, cost, and assembly method.

FAQ
What is the Zener voltage tolerance and test current for JAN1N4134D-1/TR?
JAN1N4134D-1/TR has a nominal Zener voltage of 91 V with ±1% tolerance, measured at a Zener test current (IZT) of 250 mA. This tight tolerance is achieved via post-trim screening and is specified under thermal equilibrium at 25 °C ambient, supporting high-accuracy reference design without external trimming.
Is JAN1N4134D-1/TR suitable for space applications?
Yes, JAN1N4134D-1/TR is qualified to JANS level per MIL-PRF-19500/435 and exhibits inherent radiation hardness per Microsemi MicroNote 050, making it suitable for low-earth orbit (LEO) and geosynchronous satellite applications where total ionizing dose (TID) exceeds 100 krad(Si) and parameter stability is essential.
What is the maximum reverse leakage current for JAN1N4134D-1/TR?
JAN1N4134D-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at 73 V, as specified in the Electrical Characteristics table. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision voltage divider and reference circuits.
Does JAN1N4134D-1/TR have a specified noise density?
Yes, JAN1N4134D-1/TR has a maximum noise density (ND) of 1 µV/√Hz, confirmed for voltages ≥6.8 V and verified at its 91 V operating point. This value is measured using a 1–3 kHz bandpass filter at IZT = 250 mA and 25 °C, critical for low-noise analog reference design.
What package type and marking does JAN1N4134D-1/TR use?
JAN1N4134D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by a band. It is marked with the full part number "JAN1N4134D-1" and supplied in tape-and-reel format (TR suffix denotes EIA-296 compliant packaging).
