Product details
Overview
JANTXV1N4102D-1/TR from Microsemi is a 1% tolerance, 8.7 V Zener voltage regulator diode in DO-35 glass axial package, rated for 500 mW power dissipation, -65°C to +175°C operating temperature, and qualified to MIL-PRF-19500/435 JANTXV level for high-reliability aerospace and defense systems.
For engineers reviewing the JANTXV1N4102D-1/TR datasheet, JANTXV1N4102D-1/TR pinout, JANTXV1N4102D-1/TR application, or JANTXV1N4102D-1/TR equivalent, this page delivers verified electrical parameters, military-grade qualification status, thermal derating behavior, noise density, and Zener impedance - all critical for precision voltage reference and regulation in harsh-environment analog circuits.
Technical Context
This device operates as a reverse-biased Zener regulator with a nominal 8.7 V breakdown at 250 mA test current (IZT), exhibiting 200 Ω dynamic impedance (ZZT) and ±1% initial voltage tolerance. Its metallurgically bonded construction ensures stable regulation across wide current (up to 6.7 mA IZM) and temperature ranges.
Designed for high-reliability applications, JANTXV1N4102D-1/TR features low noise density (1 µV/√Hz typical), minimal capacitance (~44 pF), and radiation-hardened behavior per Microsemi MicroNote 050. It is RoHS-compliant only in commercial versions - this JANTXV variant uses tin-lead plating and is not RoHS-compliant.
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 8.7 V, 1% tolerance, but in DO-213AA surface-mount package; no JANTXV qualification | Used where board space is constrained and MIL-spec is not required | Select for commercial industrial PCBs needing same electrical specs without military screening |
| JAN1N4102D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTXV) | Suitable for lower-tier reliability requirements such as ground-based avionics or non-flight-critical subsystems | Select when full JANTXV screening is unnecessary and cost sensitivity is higher |
Compared with JANTXV1N4102D-1/TR, 1N4102US-1 offers identical regulation but lacks hermetic axial packaging and radiation hardness, while JAN1N4102D-1 provides reduced screening depth and lower temperature survivability - both require re-evaluation of thermal management and environmental robustness in mission-critical deployments.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4102D-1/TR?
JANTXV1N4102D-1/TR has a nominal Zener voltage of 8.7 V with a tight ±1% tolerance, measured at 250 mA test current (IZT) and 25°C. This tolerance is achieved via post-process binning and is guaranteed under MIL-PRF-19500/435 JANTXV screening, making it suitable for high-accuracy reference applications where calibration stability is essential.
Is JANTXV1N4102D-1/TR RoHS compliant?
No, JANTXV1N4102D-1/TR is not RoHS compliant. As a JANTXV-qualified military-grade part, it uses traditional tin-lead plating on its axial leads per MIL-STD-750 method 2026. RoHS-compliant versions (e.g., with matte-tin plating) are available only in commercial-grade variants like 1N4102UR-1, not in JANTXV configuration.
What is the maximum Zener current (IZM) for JANTXV1N4102D-1/TR?
The maximum Zener current (IZM) for JANTXV1N4102D-1/TR is 6.7 mA at 25°C ambient. This value is derived from the 500 mW power rating and 8.7 V Zener voltage (P = V × I). Above this current, thermal derating applies linearly starting at 50°C lead temperature, reaching zero dissipation at 175°C.
How does the temperature coefficient affect JANTXV1N4102D-1/TR's performance?
JANTXV1N4102D-1/TR has a positive temperature coefficient of +0.075 %/°C, meaning its Zener voltage increases by approximately 6.5 mV per °C rise in junction temperature. This predictable drift allows compensation in precision circuits and confirms suitability for applications where monotonic voltage shift with temperature is acceptable or correctable.
What packaging and marking does JANTXV1N4102D-1/TR use?
JANTXV1N4102D-1/TR is supplied in DO-35 (DO-204AH) hermetically sealed axial-glass package with cathode indicated by a visible band. The "TR" suffix denotes tape-and-reel packaging per EIA-296 standard. Marking includes full part number "JANTXV1N4102D-1" laser-etched or ink-stamped on the glass body.
