Product details
Overview
JANS1N4102-1/TR from Microsemi is a 500 mW, 8.2 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers 8.2 V regulation at 250 mA test current, with ±5% tolerance, 200 Ω dynamic impedance, and 0.5 µA reverse leakage at 6.3 V.
For engineers reviewing the JANS1N4102-1/TR datasheet, JANS1N4102-1/TR pinout, JANS1N4102-1/TR application, or JANS1N4102-1/TR equivalent, key selection criteria include military-grade reliability qualification, low-noise performance (≤1 µV/√Hz), thermal resistance of 250 °C/W (junction-to-lead), and operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision shunt voltage reference in feedback loops and power supply regulation circuits. Its metallurgically bonded construction ensures stable Zener voltage under radiation exposure and thermal cycling, with temperature coefficient of +0.070 %/°C - enabling predictable drift compensation in wide-temperature environments.
The JANS1N4102-1/TR exhibits low capacitance (typical <2 pF at 0 V) and minimal noise density (≤1 µV/√Hz below 6.8 V), making it suitable for low-jitter analog references and sensitive instrumentation front-ends where parasitic coupling must be minimized.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4102-1 | Same electrical specs but qualified only to JANTXV level; lacks full JANS screening (e.g., burn-in, radiation testing) | Suitable for high-reliability ground-based systems where full space qualification is not mandated | Select when cost sensitivity outweighs need for Class S radiation hardness and extended temperature validation |
| 1N4102US | Surface-mount DO-213AA package; identical VZ, IZT, and αVZ, but RθJL = 300 °C/W vs. 250 °C/W | Preferred for automated assembly and compact PCB layouts where axial leads are impractical | Select when board space constraints or reflow compatibility require SMT mounting without sacrificing regulation accuracy |
Compared with JANTXV1N4102-1 and 1N4102US, the JANS1N4102-1/TR offers superior thermal performance (250 °C/W junction-to-lead), full space-level screening, and proven radiation tolerance - making it the sole choice for mission-critical avionics and spacecraft subsystems demanding guaranteed parametric stability over lifetime.

FAQ
What is the Zener voltage tolerance for JANS1N4102-1/TR?
The JANS1N4102-1/TR has a nominal Zener voltage of 8.2 V with ±5% tolerance, consistent with the standard JEDEC specification for the 1N4102-1 series. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and is maintained across the full qualified temperature range due to its JANS-level screening and metallurgical bond construction. The JANS1N4102-1/TR does not offer tighter tolerances like 2% or 1% - those are reserved for commercial-grade variants.
Is JANS1N4102-1/TR RoHS compliant?
No, the JANS1N4102-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (marked with "e3" suffix) are available only for commercial-grade parts (e.g., 1N4102-1e3), not for JANS-qualified devices. The JANS1N4102-1/TR uses traditional tin-lead plating on its axial leads to meet MIL-STD-750 solderability requirements and ensure long-term reliability under thermal cycling - a requirement that conflicts with lead-free alloy specifications.
What is the maximum Zener current IZM for JANS1N4102-1/TR?
The maximum Zener current IZM for JANS1N4102-1/TR is 40 mA, derived from its 500 mW power rating and 8.2 V Zener voltage (IZM = PM(AV)/VZ ≈ 61 mA, but datasheet specifies 40 mA as absolute maximum to ensure safe operation within thermal limits). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, and reflects conservative derating to maintain junction temperature below 175 °C under worst-case ambient conditions. The JANS1N4102-1/TR must be used within this limit to preserve long-term reliability.
Does JANS1N4102-1/TR have radiation hardness certification?
Yes, the JANS1N4102-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic glass packaging provide proven tolerance to total ionizing dose (TID) up to 100 krad(Si) and single-event effects immunity appropriate for low-earth orbit missions. This radiation hardness is a direct result of its JANS qualification per MIL-PRF-19500/435 and is verified through lot-specific radiation testing - a key differentiator from commercial or JANTXV variants. The JANS1N4102-1/TR's radiation performance is integral to its use in satellite and strategic defense platforms.
What is the thermal resistance junction-to-lead (RθJL) for JANS1N4102-1/TR?
The thermal resistance junction-to-lead (RθJL) for JANS1N4102-1/TR is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the package body, as specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2. This value enables accurate thermal modeling when mounted in chassis or heat-sinked configurations, and is 50 °C/W lower than the junction-to-ambient (RθJA) rating of 300 °C/W - confirming its suitability for lead-heat-sinking in high-reliability power regulation circuits. This RθJL is a fixed characteristic of the DO-35 package and metallurgical bond design used in the JANS1N4102-1/TR.
