Product details
Overview
JANTX1N4134C-1 from Microsemi is a 500 mW, 91 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4134C-1 datasheet, JANTX1N4134C-1 pinout, JANTX1N4134C-1 application, or JANTX1N4134C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and MIL-spec thermal derating behavior.
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 a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 1200 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTX1N4134C-1 maintains ≤0.01 µA reverse leakage at VR = 73 V and delivers 40 mW maximum noise density - falling to 1 µV/√Hz below 6.8 V - with minimal capacitance (<1.5 pF typical) and inherent radiation hardness per MicroNote 050.
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 re-layout for SMT assembly; lacks axial-lead mounting flexibility | Select when automated assembly and space-constrained layouts outweigh manual repairability needs |
| JANS1N4134C-1 | Identical electrical specs, but qualified to JANS (highest MIL reliability level) with additional screening | Required for mission-critical systems where burn-in, radiation testing, and lot traceability are mandated | Select only when JANS-level documentation and extended lifetime reliability data are contractually required |
Compared with JANTX1N4134C-1, the 1N4134US-1 offers identical regulation performance in a smaller footprint but sacrifices axial-lead serviceability, while JANS1N4134C-1 adds cost and lead time for enhanced screening without changing core electrical behavior.

FAQ
What is the Zener voltage tolerance of JANTX1N4134C-1?
JANTX1N4134C-1 has a nominal Zener voltage of 91 V with a ±2% tolerance, corresponding to the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and remains stable across its qualified operating temperature range of –65 °C to +175 °C.
Is JANTX1N4134C-1 RoHS compliant?
No, JANTX1N4134C-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions of this series; JANTX-level devices retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements and maintain proven reliability in high-reliability applications.
What is the maximum reverse leakage current for JANTX1N4134C-1?
JANTX1N4134C-1 specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 73 V. This ultra-low leakage ensures negligible current draw in standby or high-impedance sensing circuits, supporting accurate voltage monitoring without loading effects.
How does the temperature coefficient affect JANTX1N4134C-1 performance?
JANTX1N4134C-1 has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by approximately 91 mV per degree Celsius rise. This predictable positive drift enables straightforward thermal compensation in precision reference designs operating across wide ambient ranges.
Can JANTX1N4134C-1 be used in surface-mount designs?
JANTX1N4134C-1 uses a DO-35 axial-leaded package and is not designed for surface-mount assembly. For SMT compatibility, Microsemi offers the functionally equivalent 1N4134US-1 in DO-213AA package - however, that variant carries different qualification levels and is not JANTX-rated.
