Product details
Overview
JANTXV1N4103D-1/TR from Microsemi is a 500 mW, 9.1 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4103D-1/TR datasheet, JANTXV1N4103D-1/TR pinout, JANTXV1N4103D-1/TR application, or JANTXV1N4103D-1/TR equivalent, key selection criteria include its 9.1 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.5 µA maximum reverse leakage at 7.0 V, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK = 250 mA and exhibits low noise density (1 µV/√Hz typical) due to its metallurgical bond construction. Its temperature coefficient of +0.080 %/°C ensures stable regulation across wide thermal excursions in military-grade environments.
The JANTXV1N4103D-1/TR is designed for operation with cathode-banded polarity and requires no external biasing circuitry-functioning solely as a two-terminal voltage reference when reverse-biased above its Zener threshold. Its hermetically sealed DO-35 glass package provides immunity to moisture and contaminants per MIL-STD-750.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4103US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; eliminates through-hole mounting | Select when automated assembly and board space constraints outweigh manual repairability needs |
| 1N4103D-1/TR | Commercial-grade version; same 9.1 V ±1%, but only qualified to commercial reliability levels | Not screened to MIL-PRF-19500; unsuitable for flight hardware or safety-critical systems | Select for ground-test equipment or non-mission-critical prototypes where cost is prioritized |
Compared with JANTXV1N4103D-1/TR, the JANTXV1N4103US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and serviceability, while the 1N4103D-1/TR reduces cost and lead time at the expense of radiation tolerance and extended temperature validation.

FAQ
What is the Zener voltage tolerance of JANTXV1N4103D-1/TR?
JANTXV1N4103D-1/TR has a nominal Zener voltage of 9.1 V with ±1% tolerance, indicated by the "D" suffix in its nomenclature per MIL-PRF-19500/435. This tight tolerance is verified during JANTXV-level screening and ensures consistent regulation across production lots without post-manufacture calibration.
Is JANTXV1N4103D-1/TR RoHS compliant?
No, JANTXV1N4103D-1/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTXV1N4103D-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum reverse leakage current for JANTXV1N4103D-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4103D-1/TR is 0.5 µA at VR = 7.0 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is measured at 25 °C and reflects the device's ability to maintain low standby current in precision bias networks.
Can JANTXV1N4103D-1/TR be used in surface-mount designs?
No, JANTXV1N4103D-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT compatibility, Microsemi offers the functionally identical JANTXV1N4103US-1 in the DO-213AA package-same electrical specs but with solderable surface-mount terminals.
What does the "TR" suffix mean in JANTXV1N4103D-1/TR?
The "TR" suffix in JANTXV1N4103D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and does not affect electrical or reliability specifications-the JANTXV1N4103D-1/TR remains fully qualified to JANTXV level regardless of packaging method.
