For engineers reviewing the JANTX1N4624C-1 datasheet, JANTX1N4624C-1 pinout, JANTX1N4624C-1 application, or JANTX1N4624C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (1550 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (–0.050,+0.020 %/°C), and hermetic DO-35 packaging for harsh-environment operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 4.7 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across –65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness and long-term stability under thermal cycling.
The JANTX1N4624C-1 features a dynamic impedance of 1550 Ω at IZT = 250 mA and maximum reverse leakage of 3.0 µA at VR = 3.5 V, enabling accurate low-current biasing and reference generation in analog signal chains and power monitoring circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4624UR-1 | Same electrical specs but in DO-213AA surface-mount package | Required for automated SMT assembly; lacks axial lead flexibility | Select when board space is constrained and reflow compatibility is mandatory |
| JANTXV1N4624C-1 | Higher screening level (JANTXV vs JANTX); tighter parametric limits and extended burn-in | Needed for mission-critical flight hardware with zero-failure requirements | Select when system-level qualification demands enhanced reliability screening beyond JANTX |
Compared with JANTX1N4624C-1, the JANTXV variant adds burn-in and parametric screening for higher confidence in life-critical systems, while the 1N4624UR-1 provides identical regulation performance in a surface-mount form factor-neither is pin-compatible due to differing packages, and both require layout revision.

FAQ
What is the Zener voltage tolerance of JANTX1N4624C-1?
JANTX1N4624C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its measured VZ at 250 mA test current falls within 4.606 V to 4.794 V at 25 °C, supporting tighter regulation than standard ±5% variants in precision reference designs.
Is JANTX1N4624C-1 suitable for high-temperature operation?
Yes, JANTX1N4624C-1 is rated for junction temperatures from –65 °C to +175 °C and is qualified to MIL-PRF-19500/435 JANTX level. Its metallurgically bonded construction and hermetic DO-35 package ensure stable regulation and parameter retention in extended-temperature avionics and downhole electronics applications.
What does the "JANTX" prefix indicate for JANTX1N4624C-1?
The "JANTX" prefix indicates that JANTX1N4624C-1 is a military-qualified version meeting MIL-PRF-19500/435 requirements, including rigorous screening for temperature cycling, hermeticity, and parametric consistency. It carries full traceability, lot documentation, and is intended for high-reliability defense and aerospace systems.
How does the noise performance of JANTX1N4624C-1 compare to other Zeners?
JANTX1N4624C-1 delivers 1 µV/√Hz noise density at 250 mA, among the lowest in its voltage class. This outperforms typical 5% tolerance Zeners (often >10 µV/√Hz) and enables direct use in low-noise analog references without external filtering-critical for high-resolution data acquisition systems.
Can JANTX1N4624C-1 be used as a replacement for commercial 1N4624 diodes?
JANTX1N4624C-1 shares identical electrical specifications with commercial 1N4624 variants but adds military screening, traceability, and extended temperature validation. It can functionally replace commercial versions in high-reliability designs, though cost and qualification requirements may differ-always verify compliance with system-level MIL-spec requirements before substitution.
