Product details
Overview
JAN1N4117C-1 from Microsemi is a 25 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and 0.01 µA maximum reverse leakage at 19.0 V. It regulates voltage in precision reference and power supply feedback circuits across military temperature range.
For engineers reviewing the JAN1N4117C-1 datasheet, JAN1N4117C-1 pinout, JAN1N4117C-1 application, or JAN1N4117C-1 equivalent, this page delivers verified electrical parameters, mil-spec qualification status, thermal derating behavior, noise density (1 µV/√Hz), and direct alternatives for high-reliability analog design.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
It exhibits a +0.090 %/°C temperature coefficient of Zener voltage, enabling predictable drift compensation in voltage references. Maximum regulator current is 40 mA at 25 °C, with linear derating to zero at 175 °C ambient on standard PCB layout.

FAQ
What is the Zener voltage tolerance for JAN1N4117C-1?
JAN1N4117C-1 has a nominal Zener voltage of 25.0 V with a ±2% tolerance, denoted 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 military temperature range when used within its derated power envelope.
Is JAN1N4117C-1 RoHS compliant?
No, JAN1N4117C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant plating (matte tin) is available only on commercial-grade versions (e.g., 1N4117C-1e3). The JAN-level part uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements and maintain compatibility with legacy military assembly processes.
What is the maximum reverse leakage current for JAN1N4117C-1?
JAN1N4117C-1 has a maximum reverse leakage current (IR) of 0.01 µA at 19.0 V, as specified in the Electrical Characteristics table. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision reference applications where leakage-induced voltage drop must be negligible.
How does the power derating work for JAN1N4117C-1?
JAN1N4117C-1 linearly derates from 500 mW at 25 °C ambient to zero at 175 °C on a typical FR4 PCB with 1 oz copper. Derating begins at 50 °C lead temperature, with slope of –6.25 mW/°C. This behavior is defined in Figure 2 of the datasheet and must be applied in thermal design to avoid junction overheating.
What package type does JAN1N4117C-1 use?
JAN1N4117C-1 uses the DO-35 (DO-204AH) axial-leaded hermetically sealed glass package. Dimensions are specified on page 5 of the datasheet: body diameter 1.42–2.29 mm, body length 3.56–5.08 mm, lead diameter 0.46–0.56 mm, and overall length 25.4–38.1 mm.
