For engineers reviewing the JANTXV1N4617C-1 datasheet, JANTXV1N4617C-1 pinout, JANTXV1N4617C-1 application, or JANTXV1N4617C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise performance at 2.4 V, MIL-qualified reliability, thermal resistance (250 °C/W junction-to-lead), and axial-leaded DO-35 mechanical compatibility in high-reliability PCB layouts.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 2.4 V at 250 mA test current, exhibiting a temperature coefficient of –0.075 %/°C and maximum dynamic impedance of 1400 Ω. Its metallurgical bond construction ensures stable regulation across –65 °C to +175 °C junction temperature range.
Designed for high-reliability applications, JANTXV1N4617C-1 meets MIL-PRF-19500/435 requirements at JANTXV level, supports 500 mW average power dissipation (derated linearly above 50 °C), and delivers minimal capacitance and ESD insensitivity per MIL-STD-750 method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4617US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used |
| JANTXV1N4617-1 | Identical DO-35 package and Zener parameters but ±5% voltage tolerance (no C suffix) | Higher initial calibration effort needed; acceptable where post-production trimming is available | Select when cost sensitivity outweighs tight voltage tolerance requirement |
Compared with JANTXV1N4617C-1, the US-1 variant trades axial-mount flexibility for compactness, while the non-C version sacrifices 2% accuracy for broader tolerance margin - both retain identical MIL-qualified reliability and thermal performance.

FAQ
What is the Zener voltage tolerance of JANTXV1N4617C-1?
JANTXV1N4617C-1 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet, where VZ = 2.4 V at IZT = 250 mA. The tighter tolerance reduces calibration overhead in precision analog systems compared to the standard ±5% version (JANTXV1N4617-1).
Is JANTXV1N4617C-1 suitable for high-temperature operation?
Yes, JANTXV1N4617C-1 is rated for junction temperatures from –65 °C to +175 °C and is qualified to JANTXV level per MIL-PRF-19500/435. Its metallurgically bonded construction and hermetic DO-35 package ensure stable Zener voltage and low parameter drift across this full range, making it appropriate for engine-mounted avionics and downhole oilfield electronics.
Does JANTXV1N4617C-1 meet RoHS requirements?
No - JANTXV1N4617C-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTXV1N4617C-1 uses tin-lead plating per MIL-STD-750 and is intended for legacy and high-reliability applications where leaded finishes are mandated.
What is the maximum Zener current IZM for JANTXV1N4617C-1?
The maximum Zener current IZM for JANTXV1N4617C-1 is 95.0 mA, as specified in the Electrical Characteristics table on page 3 of the datasheet. This value corresponds to the 500 mW power rating at 2.4 V (P = V × I → 0.5 W / 2.4 V ≈ 208 mA), but IZM is limited by thermal constraints and dynamic impedance behavior - the 95.0 mA rating ensures safe operation within the 250 °C/W junction-to-lead thermal resistance limit.
How does the noise performance of JANTXV1N4617C-1 compare to higher-voltage Zeners?
JANTXV1N4617C-1 exhibits 1 µV/√Hz noise density at 250 mA, consistent with the datasheet's statement that noise falls quickly to 1 µV/√Hz at lower voltages. This is significantly quieter than 6.8 V+ Zeners (up to 40 µV/√Hz), making JANTXV1N4617C-1 especially valuable in ultra-low-noise 2.4 V reference designs where broadband noise directly impacts ADC ENOB and sensor resolution.
