Product details
Overview
JANTX1N4117D-1 from Microsemi is a 25 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4117D-1 datasheet, JANTX1N4117D-1 pinout, JANTX1N4117D-1 application, or JANTX1N4117D-1 equivalent, key selection criteria include its 25 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA maximum reverse leakage at 19 V, and +0.090 %/°C temperature coefficient - critical for precision reference and biasing circuits requiring stable regulation across temperature.
Technical Context
This device operates as a reverse-biased voltage regulator with a sharp breakdown knee (IZK = 250 mA), low noise density (1 µV/√Hz typical), and minimal capacitance (<1 pF at 25 V). Its metallurgical bond ensures mechanical robustness under thermal cycling and shock.
Designed for operation at lead temperature TL ≤ 50 °C, it delivers full 500 mW power rating only when mounted with ≥10 mm lead length; derating begins linearly above 50 °C and reaches zero at 175 °C junction temperature.

FAQ
What is the Zener voltage tolerance of JANTX1N4117D-1?
JANTX1N4117D-1 has a nominal Zener voltage of 25.0 V with ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, enabling high-accuracy voltage referencing without post-manufacturing adjustment. The JANTX1N4117D-1 meets this spec under MIL-PRF-19500/435 screening requirements.
Is JANTX1N4117D-1 RoHS compliant?
No, JANTX1N4117D-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 JAN, JANTX, JANTXV, or JANS reliability levels. The JANTX1N4117D-1 retains traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements.
What is the maximum reverse leakage current for JANTX1N4117D-1?
The maximum reverse leakage current for JANTX1N4117D-1 is 0.01 µA at VR = 19.0 V and 25 °C, as specified in the Electrical Characteristics table. This ultra-low leakage ensures minimal loading in high-impedance bias networks and preserves accuracy in precision reference applications where JANTX1N4117D-1 is commonly deployed.
Can JANTX1N4117D-1 be used in surface-mount designs?
No, JANTX1N4117D-1 uses a DO-35 axial-leaded glass package and is not suitable for surface-mount assembly. For SMT compatibility, Microsemi offers the functionally identical 1N4117US-1 in DO-213AA package. The JANTX1N4117D-1 requires through-hole mounting with ≥10 mm lead length for rated 500 mW dissipation.
What is the temperature coefficient of JANTX1N4117D-1?
The temperature coefficient of JANTX1N4117D-1 is +0.090 %/°C, meaning its Zener voltage increases by 0.090% per degree Celsius rise in junction temperature. This value is confirmed in the Electrical Characteristics table and supports predictable drift modeling in thermal design of JANTX1N4117D-1-based reference circuits.
