Product details
Overview
JAN1N4117C-1/TR from Microsemi is a 25 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 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 JAN1N4117C-1/TR datasheet, JAN1N4117C-1/TR pinout, JAN1N4117C-1/TR application, or JAN1N4117C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), JANS-qualified thermal stability (–65 °C to +175 °C), and hermetic DO-35 packaging for harsh-environment operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 25.0 V at 250 mA test current, exhibiting a temperature coefficient of +0.090 %/°C and dynamic impedance of 150 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling.
Designed for military-grade reliability, JAN1N4117C-1/TR maintains regulation across wide current ranges (IZK to IZM = 40 mA max) and supports low-noise analog references due to its 1 µV/√Hz noise density at 25 V - significantly lower than standard Zeners below 6.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 25.0 V ±2% at 250 mA - enables precise reference generation in regulated power rails requiring tight voltage tolerance. |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in compact axial-leaded designs with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 150 Ω at 250 mA - ensures minimal output voltage variation under load transients in feedback loops. |
| Noise Density | 1 µV/√Hz - critical for low-noise analog circuits such as precision ADC references and sensor signal conditioning. |
| Temp Coefficient αVZ | +0.090 %/°C - provides predictable, monotonic drift over –65 °C to +175 °C for mission-critical thermal environments. |
| Reverse Leakage IR | 10 µA max at 19.0 V - guarantees stable regulation onset with negligible quiescent current in standby modes. |
| Junction Temp Range | –65 °C to +175 °C - validated for extended operation in avionics, satellite power systems, and downhole electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US-1 | Same 25 V ±2% Zener voltage but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow assembly is required instead of through-hole mounting. | Select 1N4117US-1 when automated SMT production replaces manual axial insertion and thermal mass constraints apply. |
| JANTXV1N4117C-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening (burn-in, life test, hermeticity). | Required for programs demanding higher reliability assurance than JAN level, e.g., manned spacecraft avionics. | Choose JANTXV1N4117C-1 only if program spec mandates JANTXV screening; otherwise JAN1N4117C-1/TR meets most defense-tier requirements. |
Compared with 1N4117US-1 and JANTXV1N4117C-1, JAN1N4117C-1/TR delivers optimal balance of MIL-qualified performance, axial-leaded serviceability, and cost efficiency for volume-deployed defense electronics where JANTXV-level screening is not mandated.

FAQ
What is the Zener voltage tolerance of JAN1N4117C-1/TR?
JAN1N4117C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" in its part number per Microsemi's nomenclature. This corresponds to a nominal 25.0 V Zener voltage ranging from 24.5 V to 25.5 V at 250 mA test current and 25 °C ambient, enabling tighter regulation than standard ±5% variants in precision reference designs.
Is JAN1N4117C-1/TR RoHS compliant?
No, JAN1N4117C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JAN-level devices like JAN1N4117C-1/TR retain traditional tin-lead plating to meet MIL-PRF-19500/435 solderability and reliability requirements.
What is the maximum Zener current IZM for JAN1N4117C-1/TR?
The maximum Zener current IZM for JAN1N4117C-1/TR is 40 mA, derived from its 500 mW power rating and 25 V nominal Zener voltage (P = V × I → I = 0.5 W / 25 V = 20 mA), with margin added per Microsemi's published IZM value in the Electrical Characteristics table on page 3 of T4-LDS-0245-2.
Does JAN1N4117C-1/TR require heatsinking in typical applications?
No, JAN1N4117C-1/TR does not require external heatsinking in standard applications. Its DO-35 package has RθJL = 250 °C/W and RθJA = 300 °C/W; at 500 mW dissipation and 25 °C ambient, junction temperature rise is ~125 °C - within its –65 °C to +175 °C rating. Derating begins at 50 °C lead temperature per Figure 2.
How is polarity identified on JAN1N4117C-1/TR?
Polarity on JAN1N4117C-1/TR is identified by a visible cathode band on the glass DO-35 body. The banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation; reverse connection results in forward conduction at ~1.1 V, not regulation.
