For engineers reviewing the JANTX1N4116D-1/TR datasheet, JANTX1N4116D-1/TR pinout, JANTX1N4116D-1/TR application, or JANTX1N4116D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 24.0 V at 250 mA test current, dynamic impedance of 150 Ω at IZT, and reverse leakage current ≤0.01 µA at VR = 18.3 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The JANTX1N4116D-1/TR exhibits a positive temperature coefficient of +0.090 %/°C and is rated for junction temperatures from –65 °C to +175 °C. It delivers minimal capacitance (typical <2 pF) and meets MIL-STD-750 method 1020 for ESD insensitivity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and reflow compatibility is mandatory |
| JANS1N4116D-1 | Identical electrical and thermal specs, qualified to JANS (highest MIL-PRF-19500/435 level) | Required for manned spacecraft and nuclear command systems where full JANS screening is mandated | Select only when JANS-level radiation testing and lot traceability are contractually required |
Compared with JANTX1N4116D-1/TR, the 1N4116US-1 offers identical regulation performance in a compact surface-mount form factor, while JANS1N4116D-1 adds extended radiation assurance and screening rigor-neither is pin-compatible due to differing packages, making them functional alternatives rather than drop-in replacements.

FAQ
What is the Zener voltage tolerance of JANTX1N4116D-1/TR?
JANTX1N4116D-1/TR has a nominal Zener voltage of 24.0 V with a ±1% tolerance, denoted by the "D" suffix in its nomenclature. This tight tolerance is verified per MIL-PRF-19500/435 test requirements and ensures consistent regulation across production lots used in flight hardware.
Is JANTX1N4116D-1/TR RoHS compliant?
No, JANTX1N4116D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4116D-1e3); military-grade variants like JANTX1N4116D-1/TR retain tin-lead plating per MIL-STD-750 method 2026 for solderability and reliability in harsh environments.
What is the maximum operating temperature for JANTX1N4116D-1/TR?
JANTX1N4116D-1/TR is rated for junction and storage temperatures from –65 °C to +175 °C. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C, enabling reliable operation in engine bay electronics and satellite thermal control subsystems.
How does the noise performance of JANTX1N4116D-1/TR compare to lower-voltage Zeners?
JANTX1N4116D-1/TR achieves 1 µV/√Hz noise density - among the lowest in the 1N41xx series - because higher-voltage Zeners exhibit reduced shot noise. This makes JANTX1N4116D-1/TR especially valuable in precision reference applications where noise below 10 kHz directly impacts measurement resolution.
Can JANTX1N4116D-1/TR be used in surface-mount designs?
JANTX1N4116D-1/TR uses a DO-35 axial package and is not designed for surface-mount assembly. For SMT compatibility, Microsemi offers the functionally equivalent 1N4116US-1 in DO-213AA package - same electrical specs but optimized for reflow soldering and automated placement.
