Product details
Overview
JAN1N4102D-1/TR from Microsemi is a 500 mW, 8.7 V, ±1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4102D-1/TR datasheet, JAN1N4102D-1/TR pinout, JAN1N4102D-1/TR application, or JAN1N4102D-1/TR equivalent, key selection factors include its 8.7 V nominal Zener voltage at 250 mA test current, 200 Ω dynamic impedance, 0.5 µA maximum reverse leakage at 7.0 V, and radiation-hardened hermetic construction suitable for mission-critical analog reference and overvoltage protection circuits.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener test current (IZT) of 250 mA and exhibits a positive temperature coefficient of +0.075 %/°C - critical for stable biasing in wide-temperature-range instrumentation. Its metallurgical bond ensures low noise density (1 µV/√Hz typical) and minimal capacitance (<2 pF), enabling use in low-noise analog references.
The DO-35 package provides axial-leaded mounting with cathode band polarity marking and supports lead temperature derating from 500 mW at 25 °C to zero at 175 °C. It is RoHS-compliant only in commercial-grade versions; JAN1N4102D-1/TR retains legacy tin-lead plating per MIL-STD-750 method 2026.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when automated assembly and board space constraints outweigh manual serviceability needs |
| JANTXV1N4102D-1 | Identical DO-35 package and electrical parameters; differs only in screening level (JANTXV vs. JAN) | JANTXV includes extended burn-in and parametric testing beyond JAN; required for Class H military programs | Choose JANTXV1N4102D-1 if program specification mandates JANTXV-level reliability screening |
Compared with 1N4102US-1 and JANTXV1N4102D-1, JAN1N4102D-1/TR delivers optimal balance of legacy axial-mount compatibility, JANS-qualified radiation hardness, and tape-and-reel logistics for medium-volume defense production - without requiring layout change or premium screening cost.

FAQ
What is the Zener voltage tolerance of JAN1N4102D-1/TR?
JAN1N4102D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 8.7 V Zener voltage is guaranteed between 8.613 V and 8.787 V when measured at 250 mA test current and 25 °C ambient temperature. This tight tolerance supports high-accuracy reference designs without trimming.
Is JAN1N4102D-1/TR RoHS compliant?
No, JAN1N4102D-1/TR is not RoHS compliant. As a JAN-level military-qualified part, it uses traditional tin-lead plating per MIL-STD-750 method 2026. RoHS-compliant versions (e.g., with "e3" suffix) are available only in commercial-grade variants, not in JAN, JANTX, JANTXV, or JANS reliability levels.
What does the "TR" suffix indicate in JAN1N4102D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4102D-1/TR is supplied in reels containing standard quantities (typically 2,000 units), with carrier tape designed for compatibility with industrial SMT equipment - though the DO-35 package itself remains axial-leaded and through-hole mountable.
How is the polarity marked on JAN1N4102D-1/TR?
JAN1N4102D-1/TR uses a cathode band marking: a single colored band near one end of the DO-35 glass body identifies the cathode terminal. During Zener operation, the banded end must be held at a higher potential than the anode. This polarity is critical for correct shunt regulation and reverse-bias functionality.
What is the maximum Zener current (IZM) for JAN1N4102D-1/TR?
The maximum Zener current IZM for JAN1N4102D-1/TR is 40 mA, derived from its 500 mW power rating and 8.7 V Zener voltage (P = V × I → I = 0.5 W / 8.7 V ≈ 57.5 mA, derated to 40 mA per datasheet Table on Page 3). Exceeding 40 mA risks thermal runaway or permanent degradation, especially above 50 °C ambient.
