Product details
Overview
JANTXV1N4120D-1 from Microsemi is a 30 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4120D-1 datasheet, JANTXV1N4120D-1 pinout, JANTXV1N4120D-1 application, or JANTXV1N4120D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), temperature coefficient (+0.095 %/°C), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), and hermetic DO-35 packaging for radiation-hardened environments.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 30.0 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient of +0.095 %/°C above 30 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
It delivers low noise density (1 µV/√Hz) and minimal capacitance (typical 4 pF at 30 V), making it suitable for reference and biasing circuits where signal integrity and long-term stability are critical in harsh-environment analog subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4120US-1 | Same 30 V, 1% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or lead-forming | Select when automated assembly and board space constraints outweigh manual handling needs |
| JANS1N4120D-1 | Identical electrical specs but qualified to JANS level (full MIL-PRF-19500/435 screening) | Required for Class K spaceflight hardware; adds cost and lead time vs. JANTXV | Select only when mission-critical radiation tolerance and burn-in requirements exceed JANTXV scope |
Compared with JANTXV1N4120D-1, the 1N4120US-1 offers identical regulation performance in a smaller footprint but eliminates axial mounting flexibility, while JANS1N4120D-1 provides extended reliability screening at higher cost-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JANTXV1N4120D-1?
JANTXV1N4120D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 30.0 V Zener voltage is guaranteed between 29.7 V and 30.3 V at 250 mA test current and 25 °C ambient, enabling high-accuracy reference design without post-manufacture trimming.
Is JANTXV1N4120D-1 suitable for space applications?
Yes, JANTXV1N4120D-1 is qualified to MIL-PRF-19500/435 JANTXV level and exhibits inherent radiation hardness per Microsemi MicroNote 050. While not fully JANS-qualified, it is widely used in LEO satellite subsystems where TID tolerance up to 100 krad(Si) and hermetic reliability are required.
What is the maximum Zener current for JANTXV1N4120D-1?
The maximum Zener current (IZM) for JANTXV1N4120D-1 is 22.8 mA at 25 °C ambient. This value is derived from its 500 mW power rating and 30 V Zener voltage (P = V × I), and must be linearly derated above 50 °C per the published power derating curve.
Does JANTXV1N4120D-1 have low noise performance?
Yes, JANTXV1N4120D-1 delivers a noise density of 1 µV/√Hz at 250 mA test current, among the lowest in its voltage class. This makes it ideal for precision analog references, sensor excitation, and low-noise instrumentation where broadband voltage noise must be minimized.
What package type does JANTXV1N4120D-1 use?
JANTXV1N4120D-1 uses the DO-35 (DO-204AH) axial-leaded, hermetically sealed glass package. It features tin-lead or RoHS-compliant matte-tin plating, cathode band marking, and mechanical dimensions compliant with MIL-STD-1835.
