Product details
Overview
JANTX1N4110D-1/TR from Microsemi is a 16 V, 1% tolerance, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supplies.
For engineers reviewing the JANTX1N4110D-1/TR datasheet, JANTX1N4110D-1/TR pinout, JANTX1N4110D-1/TR application, or JANTX1N4110D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - all critical for precision reference and ruggedized bias design.
Technical Context
This device operates as a reverse-biased voltage regulator with nominal Zener voltage of 16.0 V at 250 mA test current, ±1% tolerance (denoted by "D" in part nomenclature), and +0.085 %/°C temperature coefficient. Its metallurgically bonded construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
It exhibits 100 Ω maximum dynamic impedance (ZZT) at IZT = 250 mA, 0.05 µA maximum reverse leakage at VR = 12.2 V, and 1 µV/√Hz typical noise density - enabling low-noise analog references in regulated power rails and sensor excitation circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4110US-1 | Same 16 V, 1% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or high-vibration mounting | Select when automated assembly and board space constraints outweigh manual serviceability needs |
| JANS1N4110D-1 | Identical electrical specs but qualified to JANS (highest MIL-PRF-19500 level); tighter screening, full lot traceability | Required for spaceflight-critical subsystems where single-point failure must be mitigated | Choose only when mission assurance requirements mandate JANS-level documentation and testing |
Compared with JANTX1N4110D-1/TR, the 1N4110US-1 trades axial-mount flexibility for SMT compatibility, while JANS1N4110D-1 adds cost and lead time for extended screening - making JANTX1N4110D-1/TR the optimal balance of reliability, serviceability, and procurement readiness for tactical and airborne systems.

FAQ
What is the Zener voltage tolerance of JANTX1N4110D-1/TR?
JANTX1N4110D-1/TR has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its part number per Microsemi's nomenclature standard. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where VZ = 16.0 V at IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration overhead in precision reference designs compared to standard 5% variants like JANTX1N4110-1.
Is JANTX1N4110D-1/TR RoHS compliant?
No, JANTX1N4110D-1/TR is not RoHS compliant. Per the datasheet note on page 1, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices. JANTX1N4110D-1/TR retains traditional tin-lead plating to meet MIL-STD-750 solderability requirements and ensure long-term reliability in harsh environments.
What is the maximum Zener current IZM for JANTX1N4110D-1/TR?
The maximum Zener current IZM for JANTX1N4110D-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value corresponds to the 500 mW power rating derated for VZ = 16.0 V (P = V × I → I = 0.5 W / 16 V ≈ 31.25 mA), with margin added per Microsemi's design practice. Operation beyond 40 mA risks exceeding thermal limits even with ideal heatsinking.
Does JANTX1N4110D-1/TR have radiation hardness certification?
Yes, JANTX1N4110D-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic seal provide resistance to total ionizing dose (TID) and displacement damage, supporting use in low-earth orbit (LEO) and high-altitude platforms without additional shielding or derating.
What does the "TR" suffix mean in JANTX1N4110D-1/TR?
The "TR" suffix in JANTX1N4110D-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. As noted on page 2 of T4-LDS-0245-2, this option is available for volume orders and requires factory consultation for minimum quantities. The "TR" does not affect electrical or reliability specifications - JANTX1N4110D-1/TR performs identically to the bulk version JANTX1N4110D-1.
