Product details
Overview
JAN1N4102-1/TR from Microsemi is a 500 mW, 8.7 V Zener diode in DO-35 glass package, qualified to JAN level per MIL-PRF-19500/435. It delivers ±5% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JAN1N4102-1/TR datasheet, JAN1N4102-1/TR pinout, JAN1N4102-1/TR application, or JAN1N4102-1/TR equivalent, key selection factors include its MIL-qualified reliability grade, low noise density (1 µV/√Hz), thermal resistance of 250 °C/W (junction-to-lead), and axial-leaded DO-35 mechanical compatibility with legacy through-hole designs.
Technical Context
This device functions as a reverse-biased voltage reference regulator with metallurgically bonded construction for enhanced stability under thermal cycling and radiation exposure. Its Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance measured using 10% rms ac modulation superimposed on IZT.
The diode exhibits a positive temperature coefficient of +0.075 %/°C and maintains regulation over wide current ranges (IZK to IZM), supporting stable operation in unregulated DC supplies and feedback networks where low capacitance (<2 pF typical) and minimal leakage (<0.5 µA at VR = 7.0 V) are critical.

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 | Requires rework for SMT assembly; no axial lead compatibility | Select when board space is constrained and automated placement is required |
| JANTX1N4102-1 | Identical DO-35 package and electrical parameters, but qualified to JANTX level with additional screening | Higher reliability screening increases cost; not needed for non-critical subsystems | Select when full JANTX qualification (including burn-in and lot acceptance tests) is mandated |
Compared with JAN1N4102-1/TR, the 1N4102US-1 offers identical regulation performance in a smaller footprint but requires layout change, while JANTX1N4102-1 adds screening rigor without altering electrical behavior-making JAN1N4102-1/TR optimal for cost-sensitive, JAN-grade aerospace subsystems requiring proven axial-leaded reliability.

FAQ
What is the Zener voltage tolerance for JAN1N4102-1/TR?
The JAN1N4102-1/TR has a nominal Zener voltage of 8.7 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under standard test conditions at 25 °C with IZT = 250 mA.
Is JAN1N4102-1/TR RoHS compliant?
No, JAN1N4102-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions-not JAN-level parts. JAN1N4102-1/TR uses traditional tin-lead plating per MIL-STD-750.
What is the maximum Zener current IZM for JAN1N4102-1/TR?
The maximum Zener current IZM for JAN1N4102-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value corresponds to the current at which the device reaches its rated 500 mW power dissipation at 25 °C lead temperature.
Does JAN1N4102-1/TR have a specified noise density?
Yes, JAN1N4102-1/TR has a maximum noise density of 1 µV/√Hz, as listed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value is measured at IZT = 250 mA within a 1 kHz–3 kHz bandpass filter at 25 °C ambient.
What is the thermal resistance junction-to-lead (RθJL) for JAN1N4102-1/TR?
The thermal resistance junction-to-lead (RθJL) for JAN1N4102-1/TR is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body, as stated in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. This value assumes standard mounting per JEDEC guidelines.
