Product details
Overview
JANTX1N4103D-1/TR from Microsemi is a 500 mW, 9.1 V, 1% tolerance Zener diode in DO-35 glass package, metallurgically bonded for high-reliability voltage regulation in aerospace and defense systems. It operates with 250 mA test current, 200 Ω dynamic impedance at IZT, and exhibits +0.080 %/°C temperature coefficient.
For engineers reviewing the JANTX1N4103D-1/TR datasheet, JANTX1N4103D-1/TR pinout, JANTX1N4103D-1/TR application, or JANTX1N4103D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), MIL-PRF-19500/435 JANTX qualification level, noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and DO-35 axial-leaded hermetic packaging.
Technical Context
This device functions as a precision shunt voltage regulator, operating in reverse breakdown with cathode-banded polarity. Its metallurgical bond ensures stable Zener voltage under thermal cycling and radiation exposure, supporting operation from –65 °C to +175 °C junction temperature.
The JANTX1N4103D-1/TR delivers 9.1 V regulation at 250 mA test current with 200 Ω dynamic impedance (ZZT) and 0.5 µA maximum reverse leakage at 7.0 V (VR). Its +0.080 %/°C temperature coefficient enables predictable drift across military temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same 9.1 V, 1% VZ, but in DO-213AA surface-mount package; no JANTX qualification | Lacks MIL-PRF-19500/435 screening; unsuitable for flight-critical hardware | Select only for commercial-grade PCBs where reflow compatibility and board space are prioritized over reliability certification |
| JANTXV1N4103D-1 | Identical electrical specs but qualified to JANTXV level (enhanced screening, tighter parametric limits) | Required for mission-critical subsystems demanding higher burn-in and life-test coverage | Choose when program requirements specify JANTXV or higher reliability grade per MIL-PRF-19500/435 |
Compared with JANTX1N4103D-1/TR, the 1N4103US-1 trades military qualification for SMT manufacturability, while JANTXV1N4103D-1 adds screening rigor without altering regulation performance-enabling grade-specific selection within the same voltage family.

FAQ
What is the Zener voltage tolerance of JANTX1N4103D-1/TR?
JANTX1N4103D-1/TR has a nominal Zener voltage of 9.1 V with ±1% tolerance, as indicated by the "D" suffix in its nomenclature. This tight tolerance is verified per MIL-PRF-19500/435 screening and applies at 250 mA test current and 25 °C ambient temperature. The JANTX1N4103D-1/TR maintains this specification across its qualified temperature range when operated within rated power limits.
Is JANTX1N4103D-1/TR RoHS compliant?
No, JANTX1N4103D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTX1N4103D-1/TR uses traditional tin-lead plating and is intended for applications where military specifications supersede RoHS requirements.
What does the "TR" suffix mean in JANTX1N4103D-1/TR?
The "TR" suffix in JANTX1N4103D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This packaging option is offered alongside bulk and ammo-pack formats. The JANTX1N4103D-1/TR retains identical electrical and reliability specifications regardless of packaging format-only mechanical handling differs.
How is the polarity marked on JANTX1N4103D-1/TR?
JANTX1N4103D-1/TR uses a black cathode band on the glass DO-35 body to indicate polarity. The banded end is the cathode and must be biased positive relative to the unbanded (anode) end for proper Zener regulation. This marking complies with JEDEC standards and is visible under standard visual inspection during manual or automated placement.
What is the maximum Zener current (IZM) for JANTX1N4103D-1/TR?
The maximum Zener current (IZM) for JANTX1N4103D-1/TR is 40 mA, derived from its 500 mW power rating and 9.1 V nominal Zener voltage (P = V × I → I = 0.5 W / 9.1 V ≈ 55 mA, derated to 40 mA per datasheet table). This value assumes operation at 25 °C lead temperature; linear derating applies above 50 °C ambient per Figure 2 in the datasheet.
