It delivers 250 mA Zener test current, 1650 Ω dynamic impedance at IZT, and operates across –65 °C to +175 °C junction temperature range in aerospace power supply reference circuits.
For engineers reviewing the JANTXV1N4622C-1 datasheet, JANTXV1N4622C-1 pinout, JANTXV1N4622C-1 application, or JANTXV1N4622C-1 equivalent, key selection factors include its 2% Zener tolerance, low noise density (1 µV/√Hz), MIL-qualified thermal stability, and axial-leaded DO-35 mechanical robustness for harsh-environment analog references.
Technical Context
This device functions as a precision shunt voltage regulator with a nominal Zener voltage of 3.9 V at 250 mA test current. Its metallurgical bond construction ensures stable breakdown characteristics and radiation hardness per Microsemi MicroNote 050, supporting operation under ionizing radiation exposure.
The diode exhibits a temperature coefficient of –0.060 %/°C and maximum reverse leakage of 2.5 µA at 3.5 V, enabling stable regulation over wide temperature and current ranges without external compensation circuitry in low-power 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 |
|---|---|---|---|
| 1N4622US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow assembly is required instead of through-hole mounting. | Select when automated SMT production and reduced profile are prioritized over manual repairability. |
| JANTXV1N4622D-1 | Identical construction and package, but tighter 1% Zener tolerance (±1%) instead of ±2%. | Deployed in metrology-grade references where absolute accuracy outweighs cost sensitivity. | Choose when calibration traceability and <1% initial error are mandatory for system-level certification. |
Compared with JANTXV1N4622C-1, the 1N4622US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-soldering ease, while JANTXV1N4622D-1 trades minor cost increase for enhanced initial accuracy-making it suitable for higher-tier test equipment where tolerance-driven error budgets dominate.

FAQ
What is the Zener voltage tolerance of JANTXV1N4622C-1?
JANTXV1N4622C-1 has a Zener voltage tolerance of ±2%, corresponding to the "C" suffix in its nomenclature. This yields a guaranteed 3.9 V regulation within 3.822 V to 3.978 V at 250 mA test current and 25 °C, meeting MIL-PRF-19500/435 requirements for JANTXV-level devices.
Is JANTXV1N4622C-1 radiation hardened?
Yes, JANTXV1N4622C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 packaging provide resistance to total ionizing dose (TID) and single-event effects, making it suitable for low-earth orbit and avionics applications without additional shielding.
What is the maximum reverse leakage current for JANTXV1N4622C-1?
The maximum reverse leakage current for JANTXV1N4622C-1 is 2.5 µA at VR = 3.5 V and 25 °C. This low IR value ensures minimal parasitic current draw in high-impedance reference networks and contributes to stable regulation under light-load conditions.
Can JANTXV1N4622C-1 be used in surface-mount designs?
No-JANTXV1N4622C-1 uses the axial-leaded DO-35 (DO-204AH) package and is not compatible with surface-mount assembly. For SMT equivalents, consider the 1N4622US-1 in DO-213AA or 1PMT4622 in DO-216, both sharing identical electrical specifications but differing in mechanical form factor.
What is the thermal resistance junction-to-lead for JANTXV1N4622C-1?
JANTXV1N4622C-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured at 3/8 inch (10 mm) lead length from body. This value supports thermal modeling for PCB layout and heatsinking decisions in high-reliability power supply designs.
