Product details
Overview
JANTX1N4102-1/TR from Microsemi is a 500 mW, 8.7 V Zener diode in DO-35 glass package, qualified to JANTX reliability 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 precision voltage regulation in military power supplies and analog reference circuits.
For engineers reviewing the JANTX1N4102-1/TR datasheet, JANTX1N4102-1/TR pinout, JANTX1N4102-1/TR application, or JANTX1N4102-1/TR equivalent, key selection criteria include Zener voltage stability over temperature, low noise density (1 µV/√Hz), hermetic DO-35 packaging, MIL-qualified reliability, and compatibility with axial-leaded PCB layouts requiring high-reliability regulation.
Technical Context
This device functions as a two-terminal reverse-biased voltage regulator, operating in breakdown mode with cathode-band polarity marking. Its metallurgically bonded junction ensures stable Zener voltage under thermal cycling and radiation exposure, supporting operation up to 175 °C junction temperature.
The JANTX1N4102-1/TR exhibits a +0.075 %/°C temperature coefficient and 0.5 µA maximum reverse leakage at 7.0 V, enabling predictable regulation across wide ambient ranges without external compensation. Its 200 Ω dynamic impedance at IZT = 250 mA defines load regulation sensitivity in feedback paths.

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 nominal Zener, but in DO-213AA surface-mount package; no axial leads | Requires rework of PCB layout; eliminates through-hole assembly but reduces mechanical robustness in vibration-prone systems | Select when board space is constrained and automated SMT placement is preferred over manual axial insertion |
| JAN1N4102-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Approved for commercial/mid-tier military use; not cleared for mission-critical avionics or space payloads | Select when cost sensitivity outweighs need for full JANTX screening, and application does not require extended burn-in or radiation testing |
Compared with JANTX1N4102-1/TR, the 1N4102US-1 offers footprint reduction at the expense of mechanical mounting strength, while JAN1N4102-1 provides identical performance with reduced reliability assurance-making JANTX1N4102-1/TR the optimal choice for high-integrity analog references where screening rigor directly impacts system lifetime.

FAQ
What is the Zener voltage tolerance for JANTX1N4102-1/TR?
JANTX1N4102-1/TR has a nominal Zener voltage of 8.7 V with a ±5% tolerance, measured at 250 mA test current and 25 °C. This tolerance is standard for the JEDEC-registered 1N4099–1N4135 series and applies across the full JANTX reliability grade without additional binning.
Is JANTX1N4102-1/TR RoHS compliant?
No, JANTX1N4102-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is available only on commercial-grade versions (e.g., 1N4102-1e3). JANTX-level parts retain tin-lead plating per MIL-STD-750 to ensure solderability and reliability in high-reliability assemblies.
What is the maximum reverse leakage current for JANTX1N4102-1/TR?
JANTX1N4102-1/TR specifies a maximum reverse leakage current (IR) of 0.5 µA at VR = 7.0 V and 25 °C. This low leakage supports high-impedance reference node integrity in precision analog circuits without introducing measurable error current.
Can JANTX1N4102-1/TR be used in surface-mount designs?
No, JANTX1N4102-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not compatible with surface-mount assembly. For SMT equivalents, consider the 1N4102US-1 in DO-213AA or 1PMT4102 in DO-216 - both share identical Zener characteristics but require different footprints and reflow profiles.
What is the thermal resistance junction-to-lead for JANTX1N4102-1/TR?
JANTX1N4102-1/TR has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body. This value guides heatsinking decisions for continuous operation near rated power, especially in confined chassis or high-ambient-temperature deployments.
