Product details
Overview
JANTX1N4104D-1 from Microsemi is a 10.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4104D-1 datasheet, JANTX1N4104D-1 pinout, JANTX1N4104D-1 application, or JANTX1N4104D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.080 %/°C), and military-grade qualification level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 10.0 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance per Figure 3. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
The JANTX1N4104D-1 features a +0.080 %/°C temperature coefficient and delivers 1 µV/√Hz noise density at its rated Zener current - optimized for low-noise reference applications where stability under thermal stress and low broadband noise are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4104US-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 manual repair. | Select when board space constraints or reflow compatibility outweigh lead-forming flexibility. |
| JANTXV1N4104D-1 | Identical parameters with enhanced screening per JANTXV level (including burn-in and 100% parametric testing). | Needed for mission-critical subsystems where failure probability must be <10-6/hour per MIL-HDBK-217F. | Select when system-level FMEA mandates higher reliability screening than JANTX level provides. |
Compared with JANTX1N4104D-1, the JANTXV variant adds burn-in and extended life testing for lower infant mortality, while the 1N4104US-1 replaces axial leads with gull-wing terminations - neither is pin-compatible due to differing packages, and both require layout revision.

FAQ
What is the Zener voltage tolerance of JANTX1N4104D-1?
JANTX1N4104D-1 has a nominal Zener voltage of 10.0 V with ±1% tolerance at 250 mA test current, as indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tight tolerance eliminates need for external trimming in precision reference designs and is verified per MIL-PRF-19500/435 screening.
Is JANTX1N4104D-1 RoHS compliant?
No, JANTX1N4104D-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4104D-1e3); military-grade variants like JANTX1N4104D-1 retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under thermal shock.
What is the maximum Zener current IZM for JANTX1N4104D-1?
The maximum Zener current IZM for JANTX1N4104D-1 is 76 mA at 25 °C, calculated from its 500 mW power rating and 10.0 V Zener voltage (IZM = PM(AV)/VZ). Derating begins linearly above 50 °C case temperature, reaching zero at 175 °C per Figure 2.
Does JANTX1N4104D-1 have radiation hardness specifications?
Yes, JANTX1N4104D-1 is inherently radiation hard per Microsemi MicroNote 050, with demonstrated tolerance to total ionizing dose (TID) up to 100 krad(Si) and single-event effects immunity typical of metallurgically bonded glass Zeners. Full radiation test reports are available upon request for qualified lots.
What package type does JANTX1N4104D-1 use?
JANTX1N4104D-1 uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, with cathode identified by a band. Dimensions comply with MIL-PRF-19500/435, including body diameter 1.42–2.29 mm and overall length 25.4–38.1 mm per Page 5 of T4-LDS-0245-2.
