Product details
Overview
JANTX1N4133D-1 from Microsemi is a 500 mW, 87 V, ±1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4133D-1 datasheet, JANTX1N4133D-1 pinout, JANTX1N4133D-1 application, or JANTX1N4133D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), dynamic impedance (1000 Ω), temperature coefficient (+0.100 %/°C), and hermetic DO-35 packaging for harsh-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 87 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C - critical for stable reference design across -65 °C to +175 °C junction temperature range.
Its metallurgical bond construction ensures low noise (1 µV/√Hz), minimal capacitance (typical <1.5 pF), and radiation hardness per Microsemi MicroNote 050, while its 500 mW power rating derates linearly from 25 °C ambient to zero at 175 °C on standard FR4 board layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 87 V ±1% at 250 mA - enables precise 87 V rail regulation with tight tolerance for mission-critical references. |
| Power Dissipation | 500 mW @ 25 °C, derated linearly to zero at 175 °C - defines thermal design margin for continuous operation in sealed enclosures. |
| Dynamic Impedance ZZT | 1000 Ω @ 250 mA - determines output voltage variation under load transients; lower values improve regulation stability. |
| Noise Density | 1 µV/√Hz @ 25 °C - supports low-noise analog references in precision instrumentation and ADC biasing. |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift with temperature; essential for predicting reference error over operational range. |
| Reverse Leakage IR | 10 nA @ 70 V - confirms minimal parasitic current below breakdown, critical for high-impedance sensing nodes. |
| Junction Temp Range | -65 °C to +175 °C - validates suitability for extended-temperature military, avionics, and downhole electronics. |
Pinout & Package
Hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode band marking; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point; establishes return path for Zener current. |
| Cathode | Regulated output node | Banded end; carries regulated 87 V when reverse-biased; must be connected to supply rail via current-limiting resistor. |
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 |
|---|---|---|---|
| JANS1N4133D-1 | Same electrical specs but qualified to JANS (highest MIL-PRF-19500/435 level) with full burn-in and radiation testing. | Required for Class S spaceflight hardware; not needed for ground-based avionics with JANTX-level assurance. | Select JANS1N4133D-1 only if full JANS screening and 100 krad(Si) TID data are mandated by program requirements. |
| 1N4133UR-1 | Surface-mount DO-213AA package; identical 87 V ±1% spec but 300 mW rating and higher thermal resistance (RθJA = 400 °C/W). | Suitable for automated assembly and compact PCB layouts where axial leads are impractical. | Choose 1N4133UR-1 when board space or reflow compatibility outweighs need for 500 mW power handling and JANTX reliability screening. |
Compared with JANS1N4133D-1, the JANTX1N4133D-1 offers identical regulation performance with reduced screening cost and lead time; versus 1N4133UR-1, it delivers higher power capability and military-grade reliability at the expense of through-hole mounting and larger footprint.

FAQ
What is the Zener voltage tolerance of JANTX1N4133D-1?
JANTX1N4133D-1 has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in the part number. This is tighter than the standard ±5% tolerance of base-number variants like JANTX1N4133-1, enabling higher-accuracy voltage references without post-manufacture trimming. The 87 V nominal value is guaranteed at 250 mA test current and 25 °C ambient.
Is JANTX1N4133D-1 suitable for high-temperature operation?
Yes, JANTX1N4133D-1 is rated for junction temperatures from -65 °C to +175 °C and is qualified per MIL-PRF-19500/435 at JANTX level. Its power dissipation linearly derates from 500 mW at 25 °C ambient to zero at 175 °C, making it suitable for engine bay, downhole, or avionics enclosure applications where thermal management is constrained.
Does JANTX1N4133D-1 have low noise performance?
Yes, JANTX1N4133D-1 delivers 1 µV/√Hz noise density at 25 °C, consistent with the 1N4133-1 series' specification for voltages ≥82 V. This low-noise characteristic results from metallurgical bond construction and supports use in precision analog circuits such as ADC references, sensor excitation, and low-drift op-amp bias networks.
What package type does JANTX1N4133D-1 use?
JANTX1N4133D-1 uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package, with cathode identified by a band. Leads are tin-lead or RoHS-compliant matte-tin plated and solderable per MIL-STD-750 method 2026. Dimensions comply with JEDEC outline DO-35, including 1.0–1.5 inch lead length and 0.056–0.090 inch body diameter.
How does JANTX1N4133D-1 differ from commercial-grade 1N4133D-1?
JANTX1N4133D-1 differs from commercial 1N4133D-1 in screening, reliability, and environmental robustness: it undergoes extended burn-in, temperature cycling, and parametric testing per MIL-PRF-19500/435, and is rated for -65 °C to +175 °C operation. Commercial versions lack military screening, have narrower temp ranges, and are not traceable to lot-level qualification data.
