Product details
Overview
JANTX1N4134D-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 MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4134D-1/TR datasheet, JANTX1N4134D-1/TR pinout, JANTX1N4134D-1/TR application, or JANTX1N4134D-1/TR equivalent, this part delivers precise 91 V regulation with low noise density (1 µV/√Hz), tight 1% voltage tolerance, and radiation-hardened performance across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable 91 V output across wide current (250 mA test current, up to 40 mA max Zener current) and temperature (–65 °C to +175 °C) variations. Its internal metallurgical bond ensures mechanical robustness and long-term stability under thermal cycling.
It exhibits a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 1200 Ω at IZT = 250 mA, enabling predictable regulation behavior in precision reference and overvoltage protection circuits where low capacitance (typ. <2 pF) and minimal leakage (<10 nA at VR = 73 V) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 91.0 V ±1% at IZT = 250 mA - enables accurate voltage clamping or reference generation in high-voltage analog circuits. |
| Power Dissipation | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - supports continuous operation in thermally constrained military enclosures. |
| Dynamic Impedance ZZT | 1200 Ω at IZT = 250 mA - ensures stable regulation under varying load conditions without excessive output ripple. |
| Noise Density ND | 1 µV/√Hz at IZT = 250 mA - critical for low-noise voltage references in precision instrumentation and ADC biasing. |
| Reverse Leakage IR | ≤10 nA at VR = 73 V - minimizes standby current in high-impedance sensing and battery-backed systems. |
| Temp Coefficient αVZ | +0.100 %/°C - allows predictable drift compensation in wide-temperature-range avionics designs. |
| Junction Temp Range | –65 °C to +175 °C - validated for operation in space-grade and engine-mounted electronics. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode band marking; leads are tin-lead plated and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; establishes Zener breakdown polarity when cathode is biased positive. |
| Cathode | Regulated output node | Banded end; connected to unregulated input; sinks current to maintain 91 V across load during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for aerospace and defense programs requiring traceable lot data and extended lifetime testing. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under shock/vibration, ensuring stable Zener voltage over 20+ year service life. |
| 1% Zener voltage tolerance | Reduces need for post-production trimming in precision reference circuits, lowering calibration cost and time. |
| Radiation hardness | Inherently resistant to total ionizing dose (TID) per Microsemi MicroNote 050 - suitable for low-earth orbit applications. |
| Low capacitance | Typical <2 pF (per Figure 3) - preserves signal integrity in RF bias networks and fast-switching protection 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%, DO-213AA surface-mount package; no axial leads; RθJA = 400 °C/W vs. 300 °C/W for DO-35. | Designed for automated SMT assembly; unsuitable for through-hole prototyping or manual repair. | Select when board space is constrained and reflow compatibility is required; verify thermal pad layout for 500 mW dissipation. |
| JANTXV1N4134D-1 | Identical electrical specs but qualified to higher JANTXV reliability level (enhanced screening, tighter parametric limits). | Required for mission-critical flight hardware where failure modes must meet MIL-HDBK-217F Class S criteria. | Choose only when program specification mandates JANTXV-level screening; adds cost and lead time without electrical benefit. |
Compared with JANTX1N4134D-1/TR, the 1N4134US-1 offers SMT compatibility at the expense of thermal performance, while JANTXV1N4134D-1 provides identical regulation with enhanced reliability screening-neither is pin-compatible due to differing packages or screening levels.

FAQ
What is the Zener voltage tolerance and test condition for JANTX1N4134D-1/TR?
JANTX1N4134D-1/TR has a nominal Zener voltage of 91.0 V with ±1% tolerance, measured at IZT = 250 mA and TJ = 25 °C. This tight tolerance eliminates need for external trimming in precision reference designs and is verified per MIL-PRF-19500/435 screening requirements.
Is JANTX1N4134D-1/TR RoHS compliant?
No, JANTX1N4134D-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4134D-1e3). JANTX-level parts retain tin-lead plating per MIL-STD-750 for solderability and reliability in high-reliability applications.
What is the maximum Zener current rating for JANTX1N4134D-1/TR?
The maximum Zener current IZM for JANTX1N4134D-1/TR is 40 mA, derived from its 500 mW power rating and 91 V nominal voltage (P = V × I → I = 500 mW / 91 V ≈ 5.5 mA, but datasheet specifies 40 mA as absolute maximum under pulsed conditions with proper thermal management).
How does the temperature coefficient affect JANTX1N4134D-1/TR in wide-temperature applications?
JANTX1N4134D-1/TR has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by ~0.091 V per 10 °C rise. This predictable positive drift allows designers to compensate reference circuits in avionics systems operating from –65 °C to +175 °C without active correction.
Can JANTX1N4134D-1/TR be used in surface-mount designs?
No, JANTX1N4134D-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4134US-1 in DO-213AA package-but note it lacks JANTX qualification and has higher thermal resistance.
