Product details
Overview
JANTX1N4134C-1/TR from Microsemi is a 500 mW, 91 V Zener diode in DO-35 glass package with ±2% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTX qualification for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTX1N4134C-1/TR datasheet, JANTX1N4134C-1/TR pinout, JANTX1N4134C-1/TR application, or JANTX1N4134C-1/TR equivalent, this page delivers verified Zener voltage (91 V), dynamic impedance (1200 Ω), noise density (1 µV/√Hz), temperature coefficient (+0.100 %/°C), and JANTX-level reliability data required for radiation-hardened analog design and military-grade power conditioning.
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 low noise density (1 µV/√Hz) and stable regulation across -65 °C to +175 °C junction temperature range. Its metallurgical bond ensures mechanical robustness under thermal cycling and shock.
The DO-35 axial-leaded glass package provides hermetic sealing and supports lead temperature derating from 500 mW at 25 °C to zero at 175 °C. Polarity is marked by cathode band; operation requires banded end positive relative to anode for Zener regulation.
Key Specifications

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 voltage and ±2% tolerance, but in surface-mount DO-213AA package | Requires PCB rework for SMT assembly; lacks axial-lead mounting flexibility | Select when space-constrained layouts or automated placement are prioritized over through-hole serviceability |
| JANTXV1N4134C-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening and 100% lot testing | Suitable for mission-critical flight control systems where failure rate must be <10-7/hr | Select when system-level reliability requirements exceed JANTX baseline, such as in launch vehicle avionics |
Compared with JANTX1N4134C-1/TR, the 1N4134US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4134C-1 adds rigorous screening for ultra-high-reliability deployment-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JANTX1N4134C-1/TR?
JANTX1N4134C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tighter tolerance enables higher accuracy in voltage reference and overvoltage protection circuits compared to standard ±5% variants like JANTX1N4134-1/TR.
Is JANTX1N4134C-1/TR RoHS compliant?
No, JANTX1N4134C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4134C-1/TR, which retain tin-lead plating for solderability and reliability in high-reliability applications.
What is the maximum operating temperature for JANTX1N4134C-1/TR?
JANTX1N4134C-1/TR has a junction and storage temperature range of -65 °C to +175 °C, as qualified per MIL-PRF-19500/435. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C, supporting operation in extreme environmental conditions typical of aerospace and defense platforms.
How is polarity marked on JANTX1N4134C-1/TR?
JANTX1N4134C-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking conforms to JEDEC DO-35 standards and is visible on the glass body of the device.
What does the "TR" suffix mean in JANTX1N4134C-1/TR?
The "TR" suffix in JANTX1N4134C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This packaging option is standard for volume orders and does not affect electrical or reliability specifications-JANTX1N4134C-1/TR maintains full JANTX qualification regardless of packaging format.
