Product details
Overview
JANTX1N4108C-1 from Microsemi is a 500 mW, 14.0 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance at IZT, used for precision voltage reference and regulation in military-grade power supply circuits.
For engineers reviewing the JANTX1N4108C-1 datasheet, JANTX1N4108C-1 pinout, JANTX1N4108C-1 application, or JANTX1N4108C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass packaging, and MIL-qualified thermal stability across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction, delivering stable 14.0 V output at 250 mA test current. Its 200 Ω dynamic impedance (ZZT) and <0.05 µA reverse leakage at 10.7 V ensure tight regulation under varying load and temperature conditions.
Designed for high-reliability environments, JANTX1N4108C-1 features inherent radiation hardness per Microsemi MicroNote 050, non-ESD-sensitive construction (MIL-STD-750 Method 1020), and minimal capacitance (~2.5 pF typical at 14 V), supporting low-noise analog references and precision biasing in avionics and space-qualified systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 14.0 V ±2% at 250 mA - ensures precise reference voltage with tight tolerance for calibration-critical circuits |

FAQ
What is the Zener voltage tolerance of JANTX1N4108C-1?
JANTX1N4108C-1 has a nominal Zener voltage of 14.0 V with a tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified under standard test conditions at 25 °C with 250 mA Zener test current and applies across the full qualified temperature range of –65 °C to +175 °C.
Is JANTX1N4108C-1 RoHS compliant?
No, JANTX1N4108C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JANTX, JANTXV, or JANS reliability levels. JANTX1N4108C-1 uses traditional tin-lead plating per MIL-STD-750 and retains lead content for solderability and reliability in high-temperature military applications.
What is the maximum Zener current IZM for JANTX1N4108C-1?
The maximum Zener current IZM for JANTX1N4108C-1 is 40 mA, derived from its 500 mW power rating and 14.0 V nominal Zener voltage (P = V × I → I = 0.5 W / 14.0 V ≈ 35.7 mA, rounded to 40 mA per datasheet specification). This value assumes operation at 25 °C ambient and linear derating above 50 °C case temperature.
Does JANTX1N4108C-1 require heatsinking in standard operation?
No, JANTX1N4108C-1 does not require external heatsinking under standard conditions. With a thermal resistance of 250 °C/W junction-to-lead (RθJL) and 300 °C/W junction-to-ambient (RθJA), it safely dissipates 500 mW at TC = 25 °C. Heatsinking becomes necessary only if sustained power dissipation exceeds 300 mW at elevated ambient temperatures (>70 °C) or in enclosed, low-airflow environments.
How is polarity marked on JANTX1N4108C-1?
JANTX1N4108C-1 uses a single black band to indicate the cathode terminal, consistent with industry-standard diode marking. During Zener regulation, the banded (cathode) end must be held at a higher potential than the unbanded (anode) end. The band is located near one lead end on the DO-35 glass body and is visible under standard visual inspection.
