Product details
Overview
JANTXV1N4120C-1 from Microsemi is a 30 V, 2% 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 JANTXV1N4120C-1 datasheet, JANTXV1N4120C-1 pinout, JANTXV1N4120C-1 application, or JANTXV1N4120C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.095 %/°C), and military-grade thermal derating behavior.
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 low dynamic impedance (200 Ω) and minimal noise density (1 µV/√Hz) - critical for stable reference generation in analog signal chains and regulated power rails.
Its metallurgical bond construction ensures robust junction integrity under thermal cycling and radiation exposure, while the DO-35 hermetic glass package supports operation across –65 °C to +175 °C junction temperature range with 250 °C/W junction-to-lead thermal resistance at 10 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 30.0 V ±2% at 250 mA - defines precise regulation point for feedback loops in DC-DC converters. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - sets maximum continuous power handling in ambient-constrained designs. |
| Dynamic Impedance ZZT | 200 Ω @ 250 mA - determines output voltage stability under load transients; lower values improve regulation accuracy. |
| Noise Density ND | 1 µV/√Hz - enables use in low-noise references where voltage ripple must be minimized (e.g., ADC references). |
| Temp Coefficient αVZ | +0.095 %/°C - quantifies drift over temperature; essential for wide-range environmental operation without external compensation. |
| Max Reverse Current IR | 0.01 µA @ 22.8 V - confirms tight leakage control below regulation threshold, reducing standby power loss. |
| Junction Temp Range | –65 °C to +175 °C - qualifies for extreme-environment deployment including space-grade and engine-mounted electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4120UR-1 | Same electrical specs, but DO-213AA surface-mount package instead of DO-35 axial lead. | Required for automated SMT assembly; lacks axial mounting flexibility and higher thermal resistance (RθJL not specified). | Select when board space is constrained and reflow compatibility is mandatory. |
| 1N4120US-1 | Commercial-grade (non-military) version; same 30 V/2% specs but only JAN/JANTX qualified, not JANTXV. | Not rated for radiation-hardened or extended-temperature mission-critical systems. | Select for cost-sensitive industrial prototypes where full JANTXV screening is unnecessary. |
Compared with JANTXV1N4120C-1, JANTXV1N4120UR-1 offers identical regulation performance in a surface-mount form factor but sacrifices axial mounting versatility and has no published RθJL; 1N4120US-1 provides identical electrical behavior at lower cost but lacks JANTXV-level screening and radiation hardness assurance.

FAQ
What is the Zener voltage tolerance of JANTXV1N4120C-1?
JANTXV1N4120C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its nominal 30.0 V Zener voltage is guaranteed between 29.4 V and 30.6 V at 250 mA test current and 25 °C, enabling tighter regulation than standard ±5% variants without trimming.
Does JANTXV1N4120C-1 meet MIL-PRF-19500/435 requirements?
Yes, JANTXV1N4120C-1 is fully qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including screening for temperature cycling, burn-in, and parametric testing. This qualification is documented in Microsemi's T4-LDS-0245-2 datasheet and confirms suitability for high-reliability aerospace and defense applications.
What is the maximum Zener current IZM for JANTXV1N4120C-1?
The maximum Zener current IZM for JANTXV1N4120C-1 is 40 mA, derived from its 500 mW power rating and 30 V nominal Zener voltage (P = V × I → I = 0.5 W / 30 V ≈ 16.7 mA), but the datasheet specifies 40 mA as the absolute maximum regulator current under defined thermal conditions - confirming safe operation up to that limit with appropriate derating.
How does the temperature coefficient affect JANTXV1N4120C-1 in wide-temperature applications?
JANTXV1N4120C-1 has a temperature coefficient of +0.095 %/°C, meaning its Zener voltage increases by approximately 28.5 mV per 10 °C rise above 25 °C. This predictable positive drift allows designers to compensate in feedback networks or select complementary components to maintain overall system accuracy across –65 °C to +175 °C operating ranges.
Is JANTXV1N4120C-1 RoHS compliant?
No, JANTXV1N4120C-1 is not RoHS compliant. Per Microsemi's documentation, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N4120C-1e3), not for JANTXV-level parts. The JANTXV1N4120C-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability in high-reliability assemblies.
