Product details
Overview
JANTX1N4102C-1 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, with ±2% voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance - used for precision voltage regulation in military power supplies and analog reference circuits.
For engineers reviewing the JANTX1N4102C-1 datasheet, JANTX1N4102C-1 pinout, JANTX1N4102C-1 application, or JANTX1N4102C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and MIL-qualified reliability for high-reliability embedded systems.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction for stable breakdown characteristics across -65 °C to +175 °C. Its 8.7 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance of 200 Ω measured at 10% AC modulation superimposed on IZT.
The diode exhibits a positive temperature coefficient of +0.075 %/°C and maximum reverse leakage of 0.5 µA at 7.0 V (VR), enabling predictable regulation over wide temperature and current ranges in analog signal conditioning and power rail stabilization.

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 electrical specs but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or repair | Select when board space is constrained and automated assembly is used |

FAQ
What is the Zener voltage tolerance of JANTX1N4102C-1?
JANTX1N4102C-1 has a nominal Zener voltage of 8.7 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when derating is applied per the power curve.
Is JANTX1N4102C-1 RoHS compliant?
No, JANTX1N4102C-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-qualified parts. The JANTX1N4102C-1 uses traditional tin-lead plating per MIL-STD-750 method 2026.
What is the maximum Zener current (IZM) for JANTX1N4102C-1?
The maximum Zener current (IZM) for JANTX1N4102C-1 is 67 mA, calculated from its 500 mW power rating and 8.7 V nominal Zener voltage (IZM = PM(AV)/VZ ≈ 500 mW / 8.7 V). This value aligns with the 67 mA entry in the Electrical Characteristics table for 1N4102-1 at 250 mA IZT.
How does the temperature coefficient affect JANTX1N4102C-1 in operation?
JANTX1N4102C-1 has a temperature coefficient of +0.075 %/°C, meaning its Zener voltage increases by approximately 6.56 mV per °C rise above 25 °C. This predictable positive drift allows designers to compensate for thermal effects in high-precision reference designs, especially in environments spanning -55 °C to +125 °C.
Can JANTX1N4102C-1 be used as a replacement for commercial 1N4102-1?
JANTX1N4102C-1 shares identical electrical specifications with commercial 1N4102-1 but adds JANTX-level screening per MIL-PRF-19500/435, including extended environmental testing and lot traceability. It is not a drop-in replacement unless the application requires MIL-qualified reliability - mechanical fit and electrical behavior are identical in DO-35 package.
