Product details
Overview
JAN1N4117D-1 from Microsemi is a 25 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4117D-1 datasheet, JAN1N4117D-1 pinout, JAN1N4117D-1 application, or JAN1N4117D-1 equivalent, key selection factors 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, ±0.09 %/°C temperature coefficient, and radiation-hardened hermetic DO-35 construction.
Technical Context
This device operates as a precision shunt voltage regulator with a sharp breakdown knee (IZK = 250 mA), enabling stable reference generation across wide current and temperature ranges. Its metallurgical bond ensures low noise density (1 µV/√Hz typical) and minimal capacitance (<1 pF at 25 V).
The JAN1N4117D-1 exhibits a positive temperature coefficient (+0.09 %/°C), making it suitable for temperature-compensated reference designs when paired with negative-coefficient devices. It is rated for junction temperatures from –65 °C to +175 °C and supports linear derating to zero power at 175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4117D-1 | Same electrical specs; qualified to JANTXV level (lower screening rigor than JANS) | Suitable for high-reliability ground-based systems where full space qualification is not required | Select when cost sensitivity outweighs need for radiation hardness and extended temperature validation |
| 1N4117UR-1 | Same Zener voltage and tolerance; surface-mount DO-213AA package instead of axial DO-35 | Used in automated SMT production lines where through-hole assembly is unavailable | Select when board space constraints or manufacturing process require SMT compatibility |
Compared with JAN1N4117D-1, JANTXV1N4117D-1 offers reduced test coverage and no radiation hardness data, while 1N4117UR-1 trades hermetic axial reliability for SMT manufacturability-neither is pin-compatible due to differing packages and qualification scopes.

FAQ
What is the Zener voltage tolerance of JAN1N4117D-1?
JAN1N4117D-1 has a ±1% Zener voltage tolerance, denoted by the "D" suffix in its nomenclature. This means its nominal 25 V Zener voltage is guaranteed between 24.75 V and 25.25 V at 250 mA test current and 25 °C ambient temperature. The tighter tolerance supports precision reference applications where standard ±5% devices would introduce unacceptable error margins.
Is JAN1N4117D-1 suitable for space applications?
Yes, JAN1N4117D-1 is qualified to JANS level per MIL-PRF-19500/435 and is inherently radiation-hardened as documented in Microsemi MicroNote 050. Its hermetic DO-35 package, metallurgical bond construction, and validated performance from –65 °C to +175 °C make it suitable for low-earth orbit and deep-space missions where single-event effects and total ionizing dose resistance are required.
What is the maximum reverse leakage current for JAN1N4117D-1?
The maximum reverse leakage current (IR) for JAN1N4117D-1 is 0.01 µA at VR = 19 V and 25 °C. This ultra-low leakage ensures minimal current draw in high-impedance reference circuits and preserves accuracy in battery-powered or low-power avionics subsystems where standby current must remain below 100 nA.
Does JAN1N4117D-1 have a specified noise density?
Yes, JAN1N4117D-1 has a specified noise density of 1 µV/√Hz at 250 mA Zener test current, measured in the 1 kHz–3 kHz band. This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 and is critical for applications such as precision ADC references and low-phase-noise oscillator biasing where broadband noise directly impacts measurement fidelity.
What package type does JAN1N4117D-1 use?
JAN1N4117D-1 uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions are defined in the Package Dimensions table on page 5 of T4-LDS-0245-2, with body diameter 1.42–2.29 mm and overall length 3.56–5.08 mm. The cathode is marked by a visible band on the glass envelope.
