Product details
Overview
JANTXV1N4109D-1/TR from Microsemi is a 15.0 V, 1% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4109D-1/TR datasheet, JANTXV1N4109D-1/TR pinout, JANTXV1N4109D-1/TR application, or JANTXV1N4109D-1/TR equivalent, key selection criteria include its 15.0 V nominal Zener voltage at 250 mA test current, 100 Ω dynamic impedance, 40 µA maximum reverse leakage at 12.0 V, and -65 °C to +175 °C operating temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics under thermal stress and radiation exposure. Its low noise density (1 µV/√Hz typical at 15 V) and minimal capacitance support low-noise analog reference and sensor biasing applications.
The JANTXV1N4109D-1/TR exhibits a positive temperature coefficient of +0.080 %/°C and is rated for 40 mA maximum Zener current at 25 °C ambient, with linear derating to zero power at 175 °C junction temperature - critical for high-temperature avionics subsystems requiring long-term parametric stability.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4109D-1/TR?
JANTXV1N4109D-1/TR has a nominal Zener voltage of 15.0 V at 250 mA test current with ±1% tolerance. This value is verified per MIL-PRF-19500/435 test procedures and applies across the full -65 °C to +175 °C operating temperature range, making JANTXV1N4109D-1/TR suitable for high-accuracy reference applications where tight voltage control is mandatory.
What does the "D" suffix mean in JANTXV1N4109D-1/TR?
The "D" suffix in JANTXV1N4109D-1/TR indicates ±1% Zener voltage tolerance per the Microsemi part nomenclature guide. It distinguishes this variant from "C" (±2%) and base (±5%) versions within the same 1N4109 family, confirming that JANTXV1N4109D-1/TR meets the tightest accuracy bin for precision regulation tasks.
Is JANTXV1N4109D-1/TR RoHS compliant?
No, JANTXV1N4109D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, while JANTXV-level devices like JANTXV1N4109D-1/TR retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum Zener current for JANTXV1N4109D-1/TR at 25 °C?
JANTXV1N4109D-1/TR supports a maximum Zener current of 40 mA at 25 °C ambient, derived from its 500 mW power rating and 15.0 V Zener voltage. This limit decreases linearly with rising junction temperature, reaching zero at +175 °C - a key constraint for thermal design in enclosed avionics enclosures where JANTXV1N4109D-1/TR is commonly deployed.
How is polarity marked on JANTXV1N4109D-1/TR?
JANTXV1N4109D-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the unmarked (anode) end for proper Zener regulation. This marking follows JEDEC DO-35 conventions and is laser-etched or ink-marked directly on the glass body, ensuring unambiguous orientation during manual or automated assembly of JANTXV1N4109D-1/TR.
