Product details
Overview
JAN1N4134C-1/TR from Microsemi is a 500 mW, 91 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JAN1N4134C-1/TR datasheet, JAN1N4134C-1/TR pinout, JAN1N4134C-1/TR application, or JAN1N4134C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for radiation-hardened analog design and legacy avionics BOM validation.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 91 V at 250 mA test current, exhibiting +0.100 %/°C temperature coefficient and 1200 Ω dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for hermetic axial-leaded mounting, it delivers low leakage (≤0.01 µA at 73 V), minimal capacitance (~4 pF typical), and noise density of 1 µV/√Hz - enabling use in low-noise analog references where long-term stability and ESD immunity (MIL-STD-750 Method 1020) are mandatory.

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, ±2%, DO-213AA surface-mount package; 300 mW rating; no JANS option | Used where board space is constrained and reflow soldering is preferred over axial through-hole | Select when footprint reduction and RoHS compliance are prioritized over military qualification |
| JANTXV1N4134C-1 | Identical electrical specs and DO-35 package; qualified only to JANTXV level (not JANS); lower screening cost | Suitable for high-reliability ground-based systems where full space-level screening is not mandated | Select when JANS-level burn-in and radiation testing are unnecessary but extended temperature and life testing are required |
Compared with JAN1N4134C-1/TR, 1N4134US-1 trades JANS qualification and 500 mW rating for SMT compatibility and RoHS compliance, while JANTXV1N4134C-1 retains the DO-35 form factor and 91 V regulation but reduces qualification scope and cost for terrestrial high-reliability use.

FAQ
What is the Zener voltage tolerance of JAN1N4134C-1/TR?
JAN1N4134C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its nominal 91 V Zener voltage falls within 89.18 V to 92.82 V at 250 mA test current and 25 °C ambient, meeting tight regulation requirements for precision reference designs.
Is JAN1N4134C-1/TR qualified to JANS level?
Yes, JAN1N4134C-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including rigorous screening for radiation hardness, thermal cycling, and long-term reliability - making it suitable for spaceflight and nuclear safety-critical applications where failure is not an option.
What is the maximum Zener current IZM for JAN1N4134C-1/TR?
The maximum Zener current IZM for JAN1N4134C-1/TR is 69.2 mA at 25 °C. This value is derived from its 500 mW power rating and 91 V Zener voltage (IZM = PM(AV)/VZ), and must be linearly derated above 50 °C ambient per the published derating curve.
Does JAN1N4134C-1/TR have RoHS compliance?
No, JAN1N4134C-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4134C-1e3); military-grade JAN/JANTX/JANTXV/JANS parts like JAN1N4134C-1/TR retain tin-lead plating per MIL-STD-750 for proven solderability and reliability in high-stress environments.
What does the "TR" suffix indicate in JAN1N4134C-1/TR?
The "TR" suffix in JAN1N4134C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and supports consistent feeding in high-throughput manufacturing lines without manual handling.
