Product details
Overview
JANTX1N4135D-1/TR from Microsemi is a 100 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTX1N4135D-1/TR datasheet, JANTX1N4135D-1/TR pinout, JANTX1N4135D-1/TR application, or JANTX1N4135D-1/TR equivalent, key selection factors include its 100 V nominal Zener voltage at 250 mA test current, ±1% voltage tolerance (denoted by "D"), RoHS-compliant matte-tin plating, and hermetically sealed DO-35 package with cathode band polarity marking.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with Zener impedance of 1600 Ω at 250 mA and maximum noise density of 1 µV/√Hz - optimized for low-noise reference applications below 10 V and stable regulation up to 100 V. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
Rated for junction temperatures from –65 °C to +175 °C and qualified to JANTX reliability level, the JANTX1N4135D-1/TR supports operation in harsh environments where long-term parametric stability and radiation hardness (per MicroNote 050) are required - including satellite power bus monitoring and avionics sensor biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 100 V at 250 mA - provides precise high-voltage reference for overvoltage clamping and supply rail regulation. |
| Zener Tolerance | ±1% - denoted by "D" suffix; enables tight voltage margin control in safety-critical feedback loops. |
| Power Dissipation | 500 mW at 25 °C - requires linear derating above 50 °C ambient; supports continuous regulation in compact layouts with adequate lead heatsinking. |
| Zener Impedance | 1600 Ω at IZT = 250 mA - indicates moderate dynamic resistance; suitable for moderate-precision references where load current variation is limited. |
| Noise Density | 1 µV/√Hz - lowest in the series; critical for analog front-end references and low-drift instrumentation designs. |
| Temp Coefficient | +0.100 %/°C - positive drift characteristic; must be compensated in wide-temperature-range voltage references. |
| Reverse Leakage | ≤0.01 µA at VR = 76 V - ensures minimal standby current in high-impedance bias networks. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package: hermetically sealed, 0.2 g mass, cathode indicated by single black band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit common or lower-potential node; defines reference point for Zener regulation. |
| Cathode | Zener breakdown terminal / regulated output node | Banded end; connected to higher-potential rail requiring stabilization; delivers 100 V ±1% when reverse-biased above knee current. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4135D-1 | Same electrical specs but qualified to JANS (highest MIL-PRF-19500 level); tighter screening, extended temperature range validation, and full lot traceability. | Required for manned spaceflight and nuclear command systems where zero-failure probability is mandated. | Select JANS1N4135D-1 only when JANS-level documentation, radiation test reports, and 100% lot testing are contractually required. |
| 1N4135DUR-1TR | Same 100 V/±1%/500 mW specs in DO-213AA surface-mount package; no axial leads; RoHS-compliant matte-tin only. | Used in automated SMT production where board space is constrained and reflow compatibility is needed. | Choose 1N4135DUR-1TR for new designs targeting high-volume manufacturing and smaller footprints - not for legacy through-hole upgrades. |
Compared with JANTX1N4135D-1/TR, JANS1N4135D-1 adds mission-critical screening overhead without electrical benefit, while 1N4135DUR-1TR trades mechanical robustness and repairability for SMT efficiency - making the JANTX variant optimal for field-serviceable, medium-volume aerospace hardware.

FAQ
What does the "D" in JANTX1N4135D-1/TR signify?
The "D" in JANTX1N4135D-1/TR denotes ±1% Zener voltage tolerance, as defined in the Microsemi nomenclature table. This tighter tolerance enables high-accuracy voltage referencing in JANTX-qualified applications such as flight control system monitors and radar bias networks where regulation error must remain under ±1 V at 100 V nominal. The JANTX1N4135D-1/TR achieves this via post-process binning and screening per MIL-PRF-19500/435.
Is JANTX1N4135D-1/TR RoHS compliant?
Yes, JANTX1N4135D-1/TR is RoHS compliant, as indicated by the "e3" suffix in its full JEDEC designation (though often omitted in shorthand). Its leads are plated with annealed matte-tin per MIL-STD-750 method 2026, and it meets exemption 7a for high-melting-point solders. Compliance applies to commercial and JANTX versions; JANTXV and JANS variants may use tin-lead depending on program requirements.
What is the maximum Zener current (IZM) for JANTX1N4135D-1/TR?
The maximum Zener current IZM for JANTX1N4135D-1/TR is 76.0 mA, derived from its 500 mW power rating and 100 V nominal Zener voltage (P = V × I). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. Operation beyond IZM risks thermal runaway, especially above 50 °C ambient due to linear derating.
How is polarity marked on JANTX1N4135D-1/TR?
JANTX1N4135D-1/TR uses a single black cathode band on the glass body to indicate polarity - the banded end is the cathode and must be connected to the higher-potential node during Zener regulation. This marking complies with JEDEC standards and is visible under standard optical inspection. Reverse connection results in forward conduction (~1.1 V drop), not regulation.
Does JANTX1N4135D-1/TR require derating at elevated temperatures?
Yes, JANTX1N4135D-1/TR must be linearly derated starting at 50 °C lead temperature, reaching zero power dissipation at 175 °C. On a typical FR4 PCB with 4 mm² copper pads, derating begins at 25 °C ambient. For example, at 100 °C ambient, its usable power drops to ~250 mW. This behavior is documented in Figure 2 of T4-LDS-0245-2 and is critical for thermal design in enclosed avionics enclosures.
