Product details
Overview
JANS1N4102D-1/TR from Microsemi is a 500 mW, 8.7 V ±1% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at IZT = 250 mA, with ZZT ≤ 200 Ω, IR ≤ 0.5 µA @ VR = 7.0 V, and αVZ = +0.075 %/°C.
For engineers reviewing the JANS1N4102D-1/TR datasheet, JANS1N4102D-1/TR pinout, JANS1N4102D-1/TR application, or JANS1N4102D-1/TR equivalent, key selection criteria include its 1% Zener tolerance, JANS-level radiation hardness, low noise density (1 µV/√Hz), hermetic DO-35 packaging, and operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band indicating polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, critical for space-grade reliability.
The JANS1N4102D-1/TR exhibits a positive temperature coefficient (+0.075 %/°C), enabling predictable drift compensation in reference circuits. Its dynamic impedance (ZZT ≤ 200 Ω at 250 mA) and low leakage (IR ≤ 0.5 µA) support stable regulation across wide current and temperature ranges without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4102D-1 | Same electrical specs and DO-35 package; qualified to JANTXV (not JANS) per MIL-PRF-19500/435 | Lacks full JANS screening (e.g., lot acceptance testing, radiation assurance documentation) | Select when JANS-level radiation hardness and full flight qualification are not required |
| 1N4102DUR-1 | Same 8.7 V ±1% Zener spec but in DO-213AA surface-mount package; no JANS qualification | Enables automated assembly and reduced board area; unsuitable for radiation-intensive or high-shock environments | Select for commercial or industrial PCBs where size, cost, and assembly efficiency outweigh military reliability needs |
Compared with JANS1N4102D-1/TR, JANTXV1N4102D-1 offers identical performance with reduced qualification rigor, while 1N4102DUR-1 trades hermetic axial packaging and JANS compliance for SMT manufacturability-making the TR-suffixed JANS variant essential for mission-critical hardware where traceability, radiation tolerance, and mechanical robustness are non-negotiable.

FAQ
What is the Zener voltage and tolerance of JANS1N4102D-1/TR?
JANS1N4102D-1/TR has a nominal Zener voltage of 8.7 V with a tight ±1% tolerance at IZT = 250 mA. This tolerance is achieved through rigorous binning and screening per MIL-PRF-19500/435, and it is explicitly specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. The "D" in the part number denotes the 1% tolerance grade.
Is JANS1N4102D-1/TR RoHS compliant?
No, JANS1N4102D-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of the datasheet, RoHS compliance (suffix "e3") is available only on commercial-grade versions. JANS-level parts use tin-lead plating per MIL-STD-750 method 2026 and are exempt from RoHS due to their high-reliability military/aerospace application requirements.
What does the "TR" suffix mean in JANS1N4102D-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. As stated on page 2 of the datasheet, this option is available for all variants in the series, and the factory must be consulted for minimum order quantities. JANS1N4102D-1/TR is supplied in moisture-barrier bags with reel labeling traceable to lot and test data.
What is the maximum power dissipation and derating behavior of JANS1N4102D-1/TR?
JANS1N4102D-1/TR has a rated average power dissipation of 500 mW at TC = 25 °C. Per the Maximum Ratings table on page 1, power must be linearly derated starting at TL = 50 °C, reaching zero at 175 °C. For ambient conditions on a typical FR4 board, derating begins at 25 °C and follows the curve in Figure 2 - meaning usable power drops to ~375 mW at 87.5 °C case temperature.
How is the polarity marked on JANS1N4102D-1/TR, and how must it be biased?
JANS1N4102D-1/TR uses a cathode band to indicate polarity, as confirmed in the Mechanical and Packaging section (page 2). The diode must be operated in reverse bias: the banded (cathode) end is connected to the higher-potential node, and the anode to the lower-potential or ground node. Forward conduction occurs at VF ≈ 1.1 V, but regulation only functions in reverse breakdown above VZ = 8.7 V.
