Product details
Overview
JANTX1N4116-1 from Microsemi is a 500 mW, 24.0 V Zener diode in DO-35 (DO-204AH) glass package, qualified to MIL-PRF-19500/435 JANTX level, with 1% voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and +0.090 %/°C temperature coefficient - used for precision voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4116-1 datasheet, JANTX1N4116-1 pinout, JANTX1N4116-1 application, or JANTX1N4116-1 equivalent, key selection criteria include Zener voltage stability over temperature, low noise density (≤1 µV/√Hz), hermetic glass packaging, MIL-qualified reliability, and axial-leaded mechanical mounting compatibility.
Technical Context
This device operates as a reverse-biased voltage reference, maintaining 24.0 V across its terminals at IZT = 250 mA with ZZT = 150 Ω and αVZ = +0.090 %/°C. It exhibits IR ≤ 0.01 µA at VR = 18.3 V and ND ≤ 1 µV/√Hz, confirming low-noise performance critical for analog sensing and reference subsystems.
Constructed with internal metallurgical bonding and hermetically sealed in axial-glass DO-35, the JANTX1N4116-1 supports junction temperatures from –65 °C to +175 °C, with RθJL = 250 °C/W and PM(AV) = 0.5 W derated linearly from 50 °C ambient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US | Same 24.0 V Zener voltage and DO-35 package but commercial-grade (non-mil-qualified); no JANTX screening or radiation hardness data. | Limited to non-safety-critical industrial controls; not approved for flight hardware or mission-critical systems. | Select only if cost sensitivity outweighs reliability requirements and environmental stress testing is waived. |
| JAN1N4116-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening rigor than JANTX); lacks burn-in and life-test validation. | Suitable for lower-tier defense programs where full JANTX qualification is not mandated by procurement spec. | Choose when budget constraints exist and program requirements permit JAN-level reliability instead of JANTX. |
Compared with JANTX1N4116-1, 1N4116US offers identical regulation performance but lacks MIL-qualified reliability evidence, while JAN1N4116-1 provides partial qualification coverage at reduced test depth - both require revalidation for flight-critical use cases.

FAQ
What is the Zener voltage tolerance for JANTX1N4116-1?
JANTX1N4116-1 has a nominal Zener voltage of 24.0 V with ±1% tolerance, confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tight tolerance eliminates need for external trimming in precision reference designs and is maintained across the full JANTX qualification screening process.
Is JANTX1N4116-1 RoHS compliant?
No, JANTX1N4116-1 is not RoHS compliant. Per the nomenclature table on page 2, RoHS-compliant versions carry the "e3" suffix (e.g., 1N4116-1e3) and are available only in commercial grade. JANTX1N4116-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 and is exempt from RoHS under military application waivers.
What is the maximum reverse leakage current for JANTX1N4116-1?
The maximum reverse leakage current (IR) for JANTX1N4116-1 is 0.01 µA at VR = 18.3 V, as specified in the Electrical Characteristics table on page 3. This ultra-low leakage supports high-impedance bias networks in analog instrumentation and ensures minimal error contribution in precision voltage reference circuits.
Does JANTX1N4116-1 have radiation hardness documentation?
Yes, JANTX1N4116-1 is inherently radiation hard as described in Microsemi MicroNote 050, referenced in the Applications/Benefits section on page 1. Its metallurgically bonded DO-35 construction and JANTX qualification per MIL-PRF-19500/435 provide documented total ionizing dose (TID) resilience suitable for low-earth orbit and avionics applications.
What is the thermal resistance from junction to lead for JANTX1N4116-1?
The thermal resistance from junction to lead (RθJL) for JANTX1N4116-1 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from body, per the Maximum Ratings table on page 1. This value guides thermal pad sizing and lead length optimization in high-reliability PCB layouts where heat dissipation must be tightly controlled.
