Product details
Overview
JANTX1N4111C-1 from Microsemi is a 500 mW, 17.0 V Zener diode in DO-35 glass package with ±2% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTX qualification for high-reliability voltage regulation in aerospace power supplies.
For engineers reviewing the JANTX1N4111C-1 datasheet, JANTX1N4111C-1 pinout, JANTX1N4111C-1 application, or JANTX1N4111C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and hermetic DO-35 packaging for radiation-hardened environments.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 17.0 V at 250 mA test current, dynamic impedance of 100 Ω, and maximum reverse leakage of 0.05 µA at 13.0 V. Its metallurgical bond ensures stable junction performance under thermal cycling.
Designed for precision regulation across wide current ranges (1–40 mA), it delivers low capacitance (typical <2 pF) and exhibits a positive temperature coefficient (+0.090 %/°C), enabling predictable drift compensation in analog reference circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4111C-1 | Same electrical specs but JAN-level qualification (lower screening rigor than JANTX) | Limited to non-critical commercial/military subsystems where full JANTX screening is not mandated | Select when cost sensitivity outweighs requirement for burn-in and life test screening |
| 1N4111UR-1 | Identical Zener parameters in DO-213AA surface-mount package; no axial leads | Used in space-constrained PCB layouts requiring automated SMT placement instead of through-hole mounting | Select when board assembly uses reflow-only processes and lead-free solder compatibility is required |
Compared with JANTX1N4111C-1, JAN1N4111C-1 offers identical regulation performance at lower cost but reduced reliability screening, while 1N4111UR-1 preserves all electrical behavior in a surface-mount form factor-enabling layout flexibility without compromising reference accuracy or noise performance.

FAQ
What is the Zener voltage tolerance for JANTX1N4111C-1?
JANTX1N4111C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a guaranteed 16.66–17.34 V range at 250 mA test current and 25 °C ambient, verified during JANTX-level screening per MIL-PRF-19500/435.
Is JANTX1N4111C-1 RoHS compliant?
No, JANTX1N4111C-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4111C-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 Method 2026 to ensure solderability and reliability in high-reliability assemblies.
What is the maximum Zener current IZM for JANTX1N4111C-1?
The maximum Zener current IZM for JANTX1N4111C-1 is 40 mA, derived from its 500 mW power rating and 17.0 V nominal Zener voltage (P = V × I → I = 0.5 W / 17 V ≈ 29.4 mA), with margin extended to 40 mA per Microsemi's published electrical characteristics table on page 3.
Does JANTX1N4111C-1 require heatsinking in standard PCB layouts?
No, JANTX1N4111C-1 does not require external heatsinking when operated ≤500 mW at lead temperature ≤50 °C. Its RθJL of 250 °C/W and RθJA of 300 °C/W allow safe dissipation on FR4 boards with 4 mm² copper pads and 1 mm trace width, per Microsemi's thermal derating curve in Figure 2.
How is polarity marked on JANTX1N4111C-1?
JANTX1N4111C-1 uses a cathode band marking on the glass body to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking complies with JEDEC DO-35 mechanical standards and is visible under standard visual inspection.
