Product details
Overview
JAN1N4111C-1 from Microsemi is a 500 mW, 17 V Zener voltage regulator diode in DO-35 glass package with 2% tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 qualification at JAN level. It regulates voltage across wide current and temperature ranges and is used in precision reference circuits for aerospace power conditioning.
For engineers reviewing the JAN1N4111C-1 datasheet, JAN1N4111C-1 pinout, JAN1N4111C-1 application, or JAN1N4111C-1 equivalent, key selection factors include its 17 V nominal Zener voltage at 250 mA test current, 100 Ω maximum dynamic impedance, ±0.090 %/°C temperature coefficient, and hermetically sealed axial-leaded DO-35 package for high-reliability environments.
Technical Context
This device operates in reverse breakdown to maintain stable 17 V output under varying load and thermal conditions. Its metallurgical bond ensures low noise density (1 μV/√Hz typical) and radiation hardness per MicroNote 050, supporting operation from –65 °C to +175 °C junction temperature.
The diode exhibits a positive temperature coefficient of +0.090 %/°C, enabling predictable voltage drift in temperature-critical systems. Its 100 Ω dynamic impedance at IZT = 250 mA and 0.05 µA maximum reverse leakage at VR = 13.0 V define regulation stability and low-power standby performance.
Key Specifications

FAQ
What is the Zener voltage and tolerance of JAN1N4111C-1?
JAN1N4111C-1 has a nominal Zener voltage of 17.0 V at 250 mA test current with a tolerance of ±2%, as indicated by the "C" suffix in the part number. This tighter tolerance reduces calibration effort in precision reference designs compared to standard 5% variants like JAN1N4111-1.
What does the "JAN" prefix signify for JAN1N4111C-1?
The "JAN" prefix denotes compliance with MIL-PRF-19500/435 at the JAN reliability level, including rigorous screening such as temperature cycling, steady-state life testing, and lot acceptance testing. JAN1N4111C-1 is fully traceable to manufacturing lots and certified for high-reliability defense and aerospace applications.
What is the maximum power dissipation and derating behavior of JAN1N4111C-1?
JAN1N4111C-1 is rated for 500 mW average power dissipation at 25 °C lead temperature. Power must be linearly derated starting at 50 °C, reaching zero at 175 °C. On a typical FR4 board, derating begins at 25 °C ambient, ensuring safe operation across its full –65 °C to +175 °C junction temperature range.
How is polarity marked and used in JAN1N4111C-1?
JAN1N4111C-1 uses a cathode band to indicate polarity. During Zener regulation, the banded (cathode) end must be held positive relative to the anode. This configuration allows the diode to operate in reverse breakdown, delivering its specified 17 V regulation voltage across the terminals.
What package type and dimensions does JAN1N4111C-1 use?
JAN1N4111C-1 is housed in a hermetically sealed axial-leaded DO-35 (DO-204AH) glass package. Body diameter is 1.42–2.29 mm, body length is 3.56–5.08 mm, and lead length is 25.4–38.1 mm. The package meets MIL-STD-750 solderability requirements and supports manual or wave soldering.
