Product details
Overview
JANS1N4102C-1/TR from Microsemi is a 500 mW, 8.7 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense systems. It delivers ±2% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4102C-1/TR datasheet, JANS1N4102C-1/TR pinout, JANS1N4102C-1/TR application, or JANS1N4102C-1/TR equivalent, key selection criteria include military-grade reliability qualification, low noise density (1 µV/√Hz), tight 2% Zener tolerance, and hermetic glass packaging suitable for radiation-hardened environments.
Technical Context
This device functions as a precision voltage reference and regulation element in analog power supply rails and signal conditioning circuits where stability under extreme thermal and radiation stress is required. Its metallurgically bonded construction ensures long-term parameter stability, while its DO-35 axial-leaded glass package provides hermetic sealing and compatibility with legacy through-hole assembly processes.
The JANS1N4102C-1/TR exhibits a positive temperature coefficient of +0.075 %/°C, enabling predictable voltage drift over temperature, and maintains ≤0.5 µA reverse leakage at 7.0 V, supporting low-power biasing in sensor front-ends and reference dividers.

FAQ
What is the Zener voltage and tolerance of JANS1N4102C-1/TR?
The JANS1N4102C-1/TR has a nominal Zener voltage of 8.7 V with a tight ±2% tolerance at 250 mA test current, as specified in the Microsemi T4-LDS-0245-2 datasheet. This tolerance is achieved via post-trim screening and is maintained across the full –65 °C to +175 °C junction temperature range, making JANS1N4102C-1/TR suitable for precision reference applications in harsh environments.
Is JANS1N4102C-1/TR qualified to JANS level per MIL-PRF-19500/435?
Yes, JANS1N4102C-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including lot-by-lot screening for parametric limits, burn-in, temperature cycling, and radiation hardness assurance. The "JANS" prefix in the part number explicitly denotes this highest military reliability level, distinguishing it from JAN, JANTX, and JANTXV variants.
What package type does JANS1N4102C-1/TR use, and is it hermetic?
JANS1N4102C-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package, which is hermetically sealed per MIL-PRF-19500/435 requirements. The glass-to-metal seal prevents moisture and contaminant ingress, ensuring long-term Zener voltage stability and reliability in vacuum, high-humidity, or corrosive environments where JANS1N4102C-1/TR is deployed.
What is the maximum power dissipation and derating behavior of JANS1N4102C-1/TR?
JANS1N4102C-1/TR has a rated average power dissipation of 500 mW at 25 °C lead temperature. Power must be linearly derated starting at 50 °C lead temperature, reaching zero at 175 °C. On a typical FR4 PCB, derating begins at 25 °C ambient, providing predictable thermal margin for JANS1N4102C-1/TR in conduction-cooled avionics and defense modules.
Does JANS1N4102C-1/TR have radiation hardness specifications?
Yes, JANS1N4102C-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide proven tolerance to total ionizing dose (TID) exceeding 100 krad(Si) and resilience against single-event effects (SEE), making JANS1N4102C-1/TR suitable for satellite, spacecraft, and nuclear instrumentation applications.
