For engineers reviewing the JANTX1N4101D-1/TR datasheet, JANTX1N4101D-1/TR pinout, JANTX1N4101D-1/TR application, or JANTX1N4101D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - all confirmed from Microsemi's official T4-LDS-0245-2 specification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 8.2 V at 250 mA test current, exhibiting +0.070 %/°C temperature coefficient and 200 Ω dynamic impedance at IZT. Its metallurgically bonded construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTX1N4101D-1/TR features hermetically sealed glass packaging, non-ESD-sensitive operation per MIL-STD-750 Method 1020, and radiation-hardened behavior documented in Microsemi MicroNote 050 - enabling use in avionics, satellite power conditioning, and hardened instrumentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US-1 | Same 8.2 V, 1% tolerance, but in surface-mount DO-213AA package; no axial leads. | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and automated assembly is used. |
| JAN1N4101D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening than JANTX). | Lacks extended burn-in and lot acceptance testing required for mission-critical avionics. | Select for cost-sensitive commercial-military hybrids where full JANTX screening is not mandated. |
Compared with JANTX1N4101D-1/TR, the 1N4101US-1 offers footprint reduction at the expense of mechanical robustness, while JAN1N4101D-1 trades qualification rigor for lower procurement cost - making JANTX1N4101D-1/TR the optimal choice for systems demanding proven reliability under MIL-PRF-19500/435 JANTX screening.

FAQ
What is the Zener voltage tolerance of JANTX1N4101D-1/TR?
JANTX1N4101D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This is confirmed in Microsemi's T4-LDS-0245-2 specification, where "D = 1%" is explicitly defined in the Part Nomenclature section. The device delivers 8.2 V ±1% at 250 mA test current, supporting high-accuracy reference design without post-manufacturing calibration.
Is JANTX1N4101D-1/TR RoHS compliant?
No, JANTX1N4101D-1/TR is not RoHS compliant. Per Microsemi's documentation, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants, not for JANTX-qualified parts. The JANTX1N4101D-1/TR uses traditional tin-lead plating on its leads and is intended for applications where military specifications and reliability supersede RoHS requirements.
What does the "TR" suffix indicate in JANTX1N4101D-1/TR?
The "TR" suffix in JANTX1N4101D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. As stated in the Mechanical and Packaging section of T4-LDS-0245-2, "Tape & Reel option: Standard per EIA-296 (add 'TR' suffix to part number)." This format supports high-volume production while maintaining full JANTX qualification integrity.
What is the maximum junction temperature rating for JANTX1N4101D-1/TR?
JANTX1N4101D-1/TR has a maximum junction and storage temperature rating of -65 °C to +175 °C, as specified in the Maximum Ratings table of T4-LDS-0245-2. This wide range supports operation in extreme environments such as engine-mounted avionics or space-qualified payloads, where thermal cycling and sustained high ambient temperatures are expected.
How is polarity marked on JANTX1N4101D-1/TR?
JANTX1N4101D-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking convention is defined in the Mechanical and Packaging section of T4-LDS-0245-2, which states: "POLARITY: Cathode indicated by band. The diode is to be operated with the banded end positive with respect to the opposite end for Zener regulation."
