Product details
Overview
JANTXV1N4616D-1 from Microsemi is a 2.2 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4616D-1 datasheet, JANTXV1N4616D-1 pinout, JANTXV1N4616D-1 application, or JANTXV1N4616D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (1300 Ω), thermal resistance (250 °C/W), and military qualification level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.2 V at 250 mA test current, exhibiting a negative temperature coefficient of –0.075 %/°C. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for low-noise analog references and regulated biasing in harsh environments, it delivers 1 µV/√Hz noise density at 2.2 V - among the lowest in its voltage class - and maintains regulation across –65 °C to +175 °C junction temperature range with hermetically sealed DO-35 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.2 V ±1% at IZT = 250 mA - enables precise low-voltage reference generation with minimal calibration drift. |
| Power Dissipation | 500 mW at TL = 25 °C - supports stable operation in compact, conduction-cooled designs without forced airflow. |
| Dynamic Impedance ZZT | 1300 Ω max - limits output voltage variation under load transients in feedback-sensing applications. |
| Noise Density | 1 µV/√Hz - critical for low-noise analog circuits such as precision instrumentation amplifiers and ADC reference buffers. |
| Temperature Coefficient αVZ | –0.075 %/°C - provides predictable, linear VZ drift over temperature for compensated reference designs. |
| Reverse Leakage IR | 2.0 µA max at VR = 1.0 V - ensures minimal quiescent current draw in battery-backed or ultra-low-power systems. |
| Junction Temp Range | –65 °C to +175 °C - validated for extended operation in space-grade and engine-mounted electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; banded end is positive during Zener regulation. Hermetically sealed, tin-lead plated leads solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or common return; defines 0 V reference point for regulation. |
| Cathode | Zener output terminal | Provides regulated 2.2 V output when reverse-biased; must be held at higher potential than anode. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Validated reliability for flight-critical avionics and satellite subsystems with full lot traceability and screening. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock, ensuring long-term parameter stability in cyclic environments. |
| 1 µV/√Hz noise density | Enables use in ultra-low-noise analog front-ends where reference-induced jitter degrades signal integrity. |
| Hermetic DO-35 glass package | Prevents moisture ingress and corrosion in high-humidity or salt-laden operational environments. |
| 1% Zener voltage tolerance | Reduces need for post-assembly trimming in precision voltage references and sensor excitation circuits. |
Applications
| Avionics Power Conditioning | Satellite Sensor Biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4616US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair. | Select when board space constraints or reflow-only manufacturing prohibit axial-leaded components. |
| 1N4616UR-1 | Commercial-grade (non-military) version; same 2.2 V/1% specs but only JAN/JANTX qualified, not JANTXV. | Lacks JANTXV screening (e.g., burn-in, thermal cycling, radiation testing); limited to non-flight hardware. | Choose for cost-sensitive ground-test equipment or lab prototypes where full MIL-PRF-19500/435 compliance is unnecessary. |
Compared with JANTXV1N4616D-1, JANTXV1N4616US-1 offers identical regulation performance in a smaller footprint but requires PCB redesign, while 1N4616UR-1 reduces cost and lead time but sacrifices radiation hardness and extended temperature validation.

FAQ
What is the Zener voltage tolerance of JANTXV1N4616D-1?
JANTXV1N4616D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance ensures consistent 2.2 V regulation across production lots and temperature extremes, supporting precision analog designs without post-manufacture calibration.
Is JANTXV1N4616D-1 suitable for high-radiation environments?
Yes, JANTXV1N4616D-1 is inherently radiation hard per Microsemi MicroNote 050 and qualified to JANTXV level per MIL-PRF-19500/435, making it suitable for satellite, nuclear, and high-altitude applications where total ionizing dose exceeds 100 krad(Si).
What is the maximum Zener test current for JANTXV1N4616D-1?
The maximum Zener test current for JANTXV1N4616D-1 is 250 mA, specified at 25 °C. This current establishes the nominal 2.2 V Zener voltage and is used to measure dynamic impedance (1300 Ω max) and noise density (1 µV/√Hz).
Does JANTXV1N4616D-1 have RoHS compliance?
No, JANTXV1N4616D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only on commercial-grade parts, not on JANTXV-qualified devices like JANTXV1N4616D-1.
What is the thermal resistance junction-to-lead for JANTXV1N4616D-1?
JANTXV1N4616D-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body. This value supports thermal design calculations for conduction-cooled mounting in high-density assemblies.
