Product details
Overview
JANS1N4101C-1/TR from Microsemi is a 500 mW, 8.2 V ±2% 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 stable regulation at 250 mA test current with 200 Ω dynamic impedance, low noise density (1 µV/√Hz), and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4101C-1/TR datasheet, JANS1N4101C-1/TR pinout, JANS1N4101C-1/TR application, or JANS1N4101C-1/TR equivalent, this page provides verified electrical specs, thermal derating behavior, radiation-hardened performance, and military-grade qualification context essential for avionics power conditioning, precision reference design, and space-qualified voltage stabilization.
Technical Context
This device functions as a two-terminal, reverse-biased Zener regulator with metallurgically bonded junction for enhanced reliability. Its 8.2 V nominal Zener voltage is specified at IZT = 250 mA, with ZZT = 200 Ω measured at 10% rms AC modulation superimposed on IZT - confirming stable regulation under dynamic load conditions.
It exhibits a positive temperature coefficient of +0.070 %/°C, enabling predictable drift compensation in multi-diode reference strings. The DO-35 package supports axial mounting with cathode band polarity marking and meets MIL-STD-750 solderability requirements, while its hermetic glass seal ensures long-term stability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 8.2 V ±2% at 250 mA - enables precise mid-range voltage reference without external trimming. |
| Power Dissipation | 500 mW @ TC = 25 °C, linearly derated to zero at 175 °C - defines maximum continuous thermal budget on PCB. |
| Dynamic Impedance ZZT | 200 Ω @ 250 mA - ensures <164 mV output variation for ±50 mA load step, critical for analog supply stability. |
| Noise Density ND | 1 µV/√Hz @ 250 mA - supports low-noise references in precision instrumentation and ADC biasing. |
| Reverse Leakage IR | 0.5 µA @ 6.3 V - guarantees minimal quiescent current draw in standby or battery-backed circuits. |
| Temp Coefficient αVZ | +0.070 %/°C - allows predictable drift modeling over –65 °C to +175 °C for mission-critical thermal compensation. |
| Junction Temp Range | –65 °C to +175 °C - validated for operation in satellite power systems and jet engine control electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4101C-1 | Same 8.2 V ±2%, DO-35 package, but qualified only to JANTXV level (not JANS); lower screening rigor and no Class S radiation assurance. | Limited to ground-based or non-spaceflight military platforms where full JANS screening is not mandated. | Select when cost sensitivity outweighs need for space-qualified radiation hardness and extended burn-in. |
| 1N4101C-1/TR (commercial) | Identical electrical specs and DO-35 form factor, but RoHS-compliant matte-tin plating and no MIL-PRF-19500 qualification; rated only for commercial temp range (–65 °C to +175 °C not guaranteed). | Suitable for industrial test equipment or non-safety-critical embedded systems requiring Zener stability without military certification. | Choose for prototyping or volume production where JANS-level reliability and traceability are unnecessary. |
Compared with JANTXV1N4101C-1 and 1N4101C-1/TR, the JANS1N4101C-1/TR uniquely combines full JANS screening, radiation hardness validation, and guaranteed –65 °C to +175 °C operation - making it the sole option for flight-critical avionics and space-qualified subsystems requiring zero-failure probability under extreme stress.

FAQ
What is the Zener voltage tolerance and test current for JANS1N4101C-1/TR?
The JANS1N4101C-1/TR has a nominal Zener voltage of 8.2 V with ±2% tolerance, verified at a Zener test current (IZT) of 250 mA. This tight tolerance ensures predictable regulation in precision reference designs, and the 250 mA test point reflects real-world operating conditions where stable thermal equilibrium is maintained in the DO-35 package.
Does JANS1N4101C-1/TR meet MIL-PRF-19500/435 requirements?
Yes, the JANS1N4101C-1/TR is fully qualified to MIL-PRF-19500/435 at the JANS level - the highest reliability tier - including rigorous screening for temperature cycling, hermeticity, radiation hardness, and lot traceability. This qualification is documented in Microsemi's T4-LDS-0245-2 specification and applies specifically to the JANS prefix variant.
What is the maximum power dissipation and thermal derating behavior of JANS1N4101C-1/TR?
JANS1N4101C-1/TR is rated for 500 mW average power dissipation at 25 °C case temperature, with linear derating to zero at 175 °C. Derating begins at 50 °C lead temperature per the datasheet curve; on a standard FR4 board, usable power drops to ~350 mW at 70 °C ambient - critical for thermal design in sealed avionics enclosures.
Is JANS1N4101C-1/TR radiation hardened, and what evidence supports this claim?
Yes, JANS1N4101C-1/TR is inherently radiation hard per Microsemi MicroNote 050, with no total ionizing dose (TID) degradation observed up to 100 krad(Si). This is a material-level property of its metallurgically bonded junction and hermetic DO-35 construction - not a post-fabrication test result - making it suitable for LEO satellite power systems.
What does the "TR" suffix indicate in JANS1N4101C-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. The JANS1N4101C-1/TR retains full JANS qualification and electrical specs; only the packaging format differs from bulk or ammo-pack versions - no performance or reliability trade-offs are introduced.
