Product details
Overview
JANTX1N4134-1/TR from Microsemi is a 500 mW, 91 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4134-1/TR datasheet, JANTX1N4134-1/TR pinout, JANTX1N4134-1/TR application, or JANTX1N4134-1/TR equivalent, key selection criteria include its 91 V nominal Zener voltage at 250 mA test current, 1200 Ω dynamic impedance, 40 µA maximum reverse leakage at 73 V, radiation-hardened construction, and hermetic DO-35 packaging for stable operation across -65°C to +175°C.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK and specified Zener impedance (ZZT) measured at 10% AC modulation superimposed on 250 mA DC test current. Its metallurgical bond ensures low noise density (1 µV/√Hz typical at low voltages) and minimal capacitance per Figure 3.
Thermal performance is defined by RθJL = 250°C/W (at 10 mm lead length) and linear power derating from 500 mW at 25°C ambient to zero at 175°C. Polarity is marked by cathode band; regulation requires banded end positive relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 91 V at 250 mA test current - defines precise regulation point for reference and clamp circuits |
| Zener Tolerance | ±5% - standard JEDEC tolerance enabling predictable worst-case voltage window in design margins |
| Power Dissipation | 500 mW at 25°C - sets maximum continuous DC power handling before thermal derating applies |
| Dynamic Impedance | 1200 Ω at 250 mA - determines output voltage stability under load current variation |
| Reverse Leakage | 40 µA max at 73 V - ensures low standby power loss and minimal regulation error near knee |
| Temp Coefficient | +0.100 %/°C - quantifies voltage drift over temperature, critical for wide-range environmental designs |
| Noise Density | 1 µV/√Hz (typical) - supports low-noise analog references where spectral purity matters |
Pinout & Package
Hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with tin-lead plating; cathode indicated by single black band; weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during Zener conduction | Connected to lower-potential node; must be held negative relative to cathode for regulation |
| Cathode | Current source during Zener conduction | Banded end; connected to higher-potential node; defines regulated output voltage referenced to anode |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for aerospace and defense systems requiring extended lifetime and mission-critical stability |
| Metallurgical bond construction | Enables low noise density and robust thermal cycling performance without epoxy-related degradation |
| Hermetic DO-35 glass package | Provides moisture immunity and long-term parameter stability in harsh environments |
| Radiation hardness | Inherently radiation-tolerant per Microsemi MicroNote 050 - suitable for space-qualified subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4134-1 | Same electrical specs; qualified to JANS (highest military reliability level) with full lot traceability and screening | Required for Class S spaceflight hardware; adds cost and lead time vs. JANTX | Select JANS1N4134-1 when full MIL-PRF-19500/435 JANS screening and radiation test reports are mandated |
| 1N4134US-1 | Same Zener voltage and DO-35 package; commercial-grade, RoHS-compliant, non-mil-qualified | Suitable only for non-critical industrial prototypes; lacks temperature cycling, burn-in, and radiation data | Select 1N4134US-1 for cost-sensitive bench validation where mil-spec compliance is not required |
Compared with JANTX1N4134-1/TR, JANS1N4134-1 delivers higher assurance for mission-critical deployment, while 1N4134US-1 offers faster availability and lower cost for non-mil development-neither is pin-compatible in terms of qualification scope, though physical form and function match.

FAQ
What is the Zener voltage tolerance for JANTX1N4134-1/TR?
JANTX1N4134-1/TR has a nominal Zener voltage of 91 V with a standard ±5% tolerance per JEDEC registration and MIL-PRF-19500/435 specification. This tolerance is verified at 250 mA test current and 25°C ambient, and applies across the full qualified temperature range of -65°C to +175°C.
Is JANTX1N4134-1/TR radiation hardened?
Yes, JANTX1N4134-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide proven tolerance to total ionizing dose (TID) and displacement damage, making it suitable for low-earth orbit and nuclear instrumentation applications.
What is the maximum reverse leakage current for JANTX1N4134-1/TR?
The maximum reverse leakage current (IR) for JANTX1N4134-1/TR is 40 µA at VR = 73 V, measured at 25°C. This value is specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 and reflects worst-case leakage well below the Zener knee for stable regulation onset.
Does JANTX1N4134-1/TR have a RoHS-compliant version?
No, JANTX1N4134-1/TR is a military-qualified part with tin-lead plating and is not RoHS compliant. RoHS-compliant versions (e.g., 1N4134US-1) exist only in commercial-grade variants marked with "e3" suffix and are not qualified to JANTX or higher reliability levels.
What is the thermal resistance junction-to-lead for JANTX1N4134-1/TR?
JANTX1N4134-1/TR has a thermal resistance junction-to-lead (RθJL) of 250°C/W when measured with 3/8 inch (10 mm) lead length from the package body. This value assumes standard mounting per MIL-PRF-19500/435 test conditions and is used to calculate safe operating current under elevated ambient temperatures.
