Product details
Overview
JANTXV1N4135D-1 from Microsemi is a 100 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4135D-1 datasheet, JANTXV1N4135D-1 pinout, JANTXV1N4135D-1 application, or JANTXV1N4135D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. Its metallurgical bond ensures stable junction behavior under thermal cycling and mechanical stress.
It exhibits a +0.100 %/°C temperature coefficient at 100 V, 250 mA test current, and 1600 Ω dynamic impedance (ZZT), with 3.8 mA maximum Zener current (IZM) and 40 µV/√Hz noise density - optimized for low-drift, low-noise analog references in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 100 V ±1% at 250 mA - enables precise 100 V regulation with tight tolerance for calibration-grade references. |
| Power Dissipation | 500 mW at 25 °C - supports stable operation in compact, convection-cooled military PCB layouts. |
| Dynamic Impedance (ZZT) | 1600 Ω at IZT = 250 mA - indicates moderate regulation stiffness; suitable for low-current reference buffering, not high-current shunt regulation. |
| Temperature Coefficient (αVZ) | +0.100 %/°C - predictable positive drift allows compensation in multi-Zener networks or temperature-stable biasing circuits. |
| Noise Density (ND) | 40 µV/√Hz at 1 kHz–3 kHz - low broadband noise supports use in precision instrumentation front-ends and ADC reference buffers. |
| Max Reverse Current (IR) | 10 nA at VR = 76 V - ensures minimal leakage below breakdown, critical for high-impedance sensing nodes. |
| Junction Temp Range | −65 °C to +175 °C - validated for extended-range operation in avionics, downhole, and space-qualified systems. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with tin-lead plating; cathode indicated by single black band; weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to system ground or lowest potential; defines Zener breakdown direction when cathode is biased positive. |
| Cathode (banded end) | Regulated output node | Provides stable 100 V reference when reverse-biased; must be driven through current-limiting resistor to maintain IZ within 3.8 mA max. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Validated reliability for flight-critical and mission-essential systems with full lot traceability and screening per military standards. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and vibration - essential for launch and re-entry environments. |
| 1% Zener voltage tolerance (D suffix) | Reduces need for post-calibration trimming in high-accuracy voltage references and sensor excitation circuits. |
| Radiation hardness (per MicroNote 050) | Inherent TID tolerance supports operation in low-earth orbit and nuclear instrumentation without derating or shielding overhead. |
| Low capacitance (typ. <2 pF) | Minimizes high-frequency coupling into reference nodes - preserves signal integrity in RF-adjacent analog subsystems. |
Applications
| Aerospace Power Reference | Defense System Calibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US-1 | Same 100 V, 1% spec, but in DO-213AA surface-mount package; no JANTXV qualification. | Used in commercial or industrial SMT designs where board space is constrained and military screening is not required. | Select only if RoHS-compliant SMT assembly and non-military reliability are acceptable. |
| JANTXV1N4135US-1 | Identical electrical specs and JANTXV qualification, but DO-213AA surface-mount instead of DO-35 axial lead. | Required for high-density, automated assembly of modern avionics modules where through-hole insertion is prohibited. | Choose when legacy DO-35 footprint cannot be accommodated and full JANTXV compliance must be retained. |
Compared with JANTXV1N4135D-1, the DO-213AA alternatives offer identical regulation performance and screening but require PCB redesign for SMT placement and lack axial-lead serviceability; the US variants also omit the D-suffix 1% tolerance marking on body, though electrical spec remains unchanged.

FAQ
What is the Zener voltage tolerance of JANTXV1N4135D-1?
JANTXV1N4135D-1 has a nominal Zener voltage of 100 V with a guaranteed tolerance of ±1%, denoted by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when used within its derated power envelope.
Is JANTXV1N4135D-1 suitable for radiation-exposed environments?
Yes, JANTXV1N4135D-1 is inherently radiation-hardened as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and glass DO-35 package provide proven tolerance to total ionizing dose (TID) without parameter degradation, making it suitable for satellite, nuclear, and high-altitude avionics applications.
What is the maximum Zener current rating for JANTXV1N4135D-1?
The maximum Zener current (IZM) for JANTXV1N4135D-1 is 3.8 mA at 25 °C, derived from its 500 mW power rating and 100 V Zener voltage. Operation above this current requires strict thermal management and linear derating above 50 °C lead temperature per Figure 2 in the datasheet.
Does JANTXV1N4135D-1 have a specified noise density?
Yes, JANTXV1N4135D-1 has a maximum noise density of 40 µV/√Hz, measured in the 1 kHz–3 kHz band at 250 mA Zener test current and 25 °C ambient. This value is consistent with the 1N4135-1 series specification and confirms suitability for low-noise analog reference applications.
How is polarity marked on JANTXV1N4135D-1?
JANTXV1N4135D-1 uses a single black band on the glass body to indicate the cathode terminal. The diode must be operated in reverse bias - i.e., the banded (cathode) end must be held positive relative to the unbanded (anode) end - to achieve Zener regulation at 100 V.
