Product details
Overview
JANTX1N4104D-1/TR from Microsemi is a 1% tolerance, 10.0 V, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4104D-1/TR datasheet, JANTX1N4104D-1/TR pinout, JANTX1N4104D-1/TR application, or JANTX1N4104D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), dynamic impedance (200 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.080 %/°C), and JANTX-level qualification for extended temperature operation.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics across -65 °C to +175 °C. Its low noise density (1 µV/√Hz) and tight 1% Zener voltage tolerance support reference-grade stability in analog measurement and sensor excitation circuits.
The DO-35 package provides hermetic glass sealing and axial leads compatible with through-hole mounting and wave soldering. Thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length, enabling reliable 500 mW dissipation when properly heatsunk.

FAQ
What is the Zener voltage and tolerance of JANTX1N4104D-1/TR?
JANTX1N4104D-1/TR has a nominal Zener voltage of 10.0 V with a tight ±1% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is achieved via post-process binning and is guaranteed under MIL-PRF-19500/435 JANTX screening, making JANTX1N4104D-1/TR suitable for high-accuracy reference applications where drift and initial error must be minimized.
Is JANTX1N4104D-1/TR RoHS compliant?
No, JANTX1N4104D-1/TR is not RoHS compliant. The "e3" RoHS suffix is available only on commercial-grade versions (e.g., 1N4104D-1e3). JANTX1N4104D-1/TR uses traditional tin-lead plating per MIL-STD-750 and is intended for high-reliability applications where leaded finishes are specified for solder joint integrity and long-term intermetallic stability.
What is the maximum power dissipation and derating behavior of JANTX1N4104D-1/TR?
JANTX1N4104D-1/TR is rated for 500 mW average power dissipation at 25 °C lead temperature, with linear derating beginning at 50 °C and reaching zero at 175 °C. Derating is defined per MIL-PRF-19500/435 and applies to both ambient and lead temperature conditions; actual usable power depends on PCB copper area, lead length, and airflow-JANTX1N4104D-1/TR must be mounted with ≥10 mm lead length for specified RθJL = 250 °C/W.
How does the temperature coefficient of JANTX1N4104D-1/TR affect its performance?
JANTX1N4104D-1/TR has a temperature coefficient of +0.080 %/°C, meaning its Zener voltage increases by approximately 8 mV per °C rise in junction temperature. This predictable, monotonic drift allows designers to compensate in circuit layout or firmware; it also indicates operation near the zero-TC crossover point for 10 V Zeners, minimizing curvature error over moderate temperature spans.
What packaging and marking format does JANTX1N4104D-1/TR use?
JANTX1N4104D-1/TR is supplied in DO-35 (DO-204AH) hermetically sealed glass axial-leaded package with cathode identified by a single black band. It is marked with the full part number "JANTX1N4104D-1" and packaged in tape-and-reel per EIA-296 (the "TR" suffix denotes this format); weight is approximately 0.2 grams, and leads are tin-lead solderable per MIL-STD-750 method 2026.
