Product details
Overview
JAN1N4117-1 from Microsemi is a 500 mW, 25.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4117-1 datasheet, JAN1N4117-1 pinout, JAN1N4117-1 application, or JAN1N4117-1 equivalent, key selection criteria include its 25.0 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA maximum reverse leakage at 19.0 V, and +0.090 %/°C temperature coefficient - critical for precision reference stability across military temperature ranges.
Technical Context
This device operates as a two-terminal shunt voltage regulator with cathode-banded polarity, requiring external current limiting. Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical at 25 V), minimal capacitance (~15 pF), and inherent radiation hardness per Microsemi MicroNote 050.
It delivers stable regulation over -65 °C to +175 °C junction temperature, with thermal resistance of 250 °C/W junction-to-lead (3/8″ lead length) and linear power derating from 500 mW at 25 °C to zero at 175 °C on standard FR4 PCBs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US | Same 25 V Zener voltage and DO-35 package but commercial-grade (non-mil-qualified); RoHS-compliant matte-tin plating | Lacks JAN screening, radiation hardness, and extended temperature validation; suitable only for non-critical industrial use | Select when cost and RoHS compliance outweigh military reliability requirements |
| JANTXV1N4117 | Identical electrical specs and DO-35 package, but qualified to JANTXV level with enhanced screening and tighter lot traceability | Approved for higher-tier defense programs requiring burn-in, life testing, and lot-specific radiation data | Select when program mandates JANTXV-level documentation and extended reliability assurance |
Compared with JAN1N4117-1, 1N4117US offers lower cost and RoHS compliance but no military qualification, while JANTXV1N4117 provides superior screening and documentation for Tier-1 defense contracts - neither is pin-compatible drop-in replacement due to differing qualification scope and sourcing controls.

FAQ
What is the Zener voltage tolerance for JAN1N4117-1?
JAN1N4117-1 has a nominal Zener voltage of 25.0 V with a standard ±5% tolerance, consistent with JEDEC registration for the 1N4099–1N4135 family. This tolerance applies at 250 mA test current and 25 °C ambient, and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Is JAN1N4117-1 RoHS compliant?
No, JAN1N4117-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4117-1e3); JAN-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum reverse leakage current for JAN1N4117-1?
JAN1N4117-1 specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 19.0 V, measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision reference applications across the full military temperature range.
Can JAN1N4117-1 be used in surface-mount designs?
No, JAN1N4117-1 is exclusively packaged in the axial-leaded DO-35 (DO-204AH) through-hole format. Surface-mount alternatives include the JANS-rated 1N4117UR-1 in DO-213AA or 1PMT4117 in DO-216, which share identical electrical specs but differ in mechanical form factor and qualification scope.
What is the thermal resistance specification for JAN1N4117-1?
JAN1N4117-1 has a thermal resistance of 250 °C/W junction-to-lead (RθJL) when measured with 3/8″ (10 mm) lead length from body, and 300 °C/W junction-to-ambient (RθJA) on FR4 PCB with 4 mm² copper pads. These values govern safe power derating above 25 °C ambient per Figure 2 in the T4-LDS-0245-2 datasheet.
