Product details
Overview
JAN1N4117D-1/TR 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, reference circuits, and overvoltage protection.
For engineers reviewing the JAN1N4117D-1/TR datasheet, JAN1N4117D-1/TR pinout, JAN1N4117D-1/TR application, or JAN1N4117D-1/TR 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, ±0.090 %/°C temperature coefficient, and hermetically sealed axial-leaded construction for stable operation across –65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a sharp breakdown knee (IZK = 250 mA), enabling stable regulation across wide current ranges (1–40 mA) and temperatures. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at 25 V) and radiation hardness per MicroNote 050.
The diode exhibits a positive temperature coefficient (+0.090 %/°C), making it suitable for temperature-compensated reference designs when paired with negative-coefficient devices. It is rated for 0.5 W average power dissipation with linear derating above 50 °C lead temperature and requires cathode-band orientation for proper Zener biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 25.0 V ±1% at IZT = 250 mA - precise reference point for calibration and feedback loops |
| Dynamic Impedance ZZT | 150 Ω at IZT = 250 mA - low AC impedance ensures minimal output voltage variation under load transients |
| Max Reverse Leakage IR | 0.01 µA at VR = 19.0 V - ultra-low leakage preserves accuracy in high-impedance bias networks |
| Temp Coefficient αVZ | +0.090 %/°C - predictable drift enables compensation in precision analog systems |
| Noise Density ND | 1 µV/√Hz at IZT = 250 mA - exceptionally low broadband noise for sensitive reference applications |
| Power Dissipation PM(AV) | 500 mW @ TC = 25 °C - supports robust regulation in compact, unheatsinked layouts |
| Junction Temp Range TJ | –65 °C to +175 °C - validated for extreme-environment operation in military avionics and space-grade electronics |
Pinout & Package

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 electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mounting | Select when board space is constrained and reflow compatibility is required |
| JANTXV1N4117D-1 | Identical Zener parameters and 1% tolerance; differs only in qualification level (JANTXV vs. JAN) | JANTXV includes additional screening (burn-in, thermal shock) for extended life in flight-critical subsystems | Select for manned aerospace platforms where failure mode analysis mandates enhanced screening |
Compared with JAN1N4117D-1/TR, the 1N4117US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-solderability, while JANTXV1N4117D-1 delivers identical electrical behavior with higher reliability assurance at increased cost and longer lead time.

FAQ
What is the Zener voltage tolerance of JAN1N4117D-1/TR?
JAN1N4117D-1/TR has a nominal Zener voltage of 25.0 V with a tight ±1% tolerance, denoted 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 reference design without post-manufacturing trimming. The 1% spec applies across the full qualified temperature range when used within derated power limits.
Is JAN1N4117D-1/TR suitable for high-temperature operation?
Yes, JAN1N4117D-1/TR is rated for junction temperatures from –65 °C to +175 °C and qualified to JANS level per MIL-PRF-19500/435. Its metallurgically bonded construction and hermetic glass package ensure stable Zener voltage and low leakage up to 175 °C, provided power dissipation is linearly derated above 50 °C lead temperature per Figure 2 in the datasheet.
What does the "TR" suffix mean in JAN1N4117D-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4117D-1/TR contains the same die, electrical specifications, and MIL qualification as JAN1N4117D-1, with no performance difference-only packaging format changes to support high-volume SMT manufacturing workflows.
How does JAN1N4117D-1/TR compare to commercial-grade 1N4117D-1?
JAN1N4117D-1/TR is the JAN-level qualified version, meaning it undergoes additional screening including lot acceptance testing, electrical verification across temperature extremes, and compliance with MIL-PRF-19500/435. Commercial 1N4117D-1 lacks this screening and is not approved for military or space applications, though both share identical nominal Zener voltage, impedance, and noise characteristics.
What is the maximum reverse leakage current for JAN1N4117D-1/TR?
JAN1N4117D-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 19.0 V, measured at 25 °C. This ultra-low leakage ensures minimal error in high-impedance reference divider networks and preserves accuracy in battery-powered or low-power instrumentation where standby current must be minimized.
