Product details
Overview
JANS1N4117D-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 aerospace and defense voltage regulation. It delivers stable reference voltage across wide current (250 mA test) and temperature (−65 °C to +175 °C) ranges with low dynamic impedance (150 Ω) and minimal noise density (1 µV/√Hz).
For engineers reviewing the JANS1N4117D-1/TR datasheet, JANS1N4117D-1/TR pinout, JANS1N4117D-1/TR application, or JANS1N4117D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), radiation hardness, hermetic glass packaging, MIL-spec qualification level, and thermal derating behavior above 50 °C.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, critical for space-grade applications.
It exhibits a positive temperature coefficient of +0.090 %/°C and maintains ≤150 Ω dynamic impedance at IZT = 250 mA, enabling tight regulation in low-noise analog references and power supply feedback loops where long-term drift and ESD immunity matter.
Key Specifications

Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package. Cathode identified by single black band; banded end is anode when used as forward diode, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to system ground or common return; establishes reference potential for regulated output |
| Cathode (banded end) | Zener output node | Provides stabilized 25 V output when reverse-biased; must be connected to unregulated input via current-limiting resistor |

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 25 V ±1%, DO-35, but qualified only to JANTXV level (not JANS); lower screening severity and no radiation hardness documentation | Limited to ground-based military systems without TID or SEE requirements | Select when full JANS qualification is not mandated and cost reduction is prioritized |
| 1N4117D-1/TR | Commercial-grade version: RoHS-compliant matte tin plating, no MIL-PRF-19500 qualification, same electrical specs | Restricted to non-safety-critical industrial or telecom infrastructure | Choose for prototyping or commercial derivatives where traceability and extended temp range are secondary |
Compared with JANTXV1N4117D-1 and 1N4117D-1/TR, JANS1N4117D-1/TR uniquely provides documented radiation hardness, full Class S screening, and guaranteed performance from −65 °C to +175 °C - essential for launch vehicle power conditioning and on-orbit electronics.

FAQ
What is the Zener voltage tolerance of JANS1N4117D-1/TR?
JANS1N4117D-1/TR has a nominal Zener voltage of 25.0 V with a tight ±1% tolerance, indicated by the "D" suffix in its nomenclature. This tolerance is verified per MIL-PRF-19500/435 screening and applies across the full operating temperature range of −65 °C to +175 °C, making JANS1N4117D-1/TR suitable for high-accuracy reference applications where calibration margin is constrained.
Is JANS1N4117D-1/TR radiation-hardened?
Yes, JANS1N4117D-1/TR is inherently radiation hard as described in Microsemi MicroNote 050 and qualified to JANS level per MIL-PRF-19500/435. Its metallurgically bonded glass construction and process controls ensure survivability under total ionizing dose (TID) up to 100 krad(Si) and resilience against single-event effects - a core requirement confirmed for JANS1N4117D-1/TR in space-grade power systems.
What does the "TR" suffix mean in JANS1N4117D-1/TR?
The "TR" suffix in JANS1N4117D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-reliability PCB assembly lines. This packaging format is standard for JANS1N4117D-1/TR and includes full lot traceability, humidity barrier bagging, and desiccant - all required for controlled handling of JANS-class components during JANS1N4117D-1/TR integration into flight hardware.
What is the maximum Zener current IZM for JANS1N4117D-1/TR?
The maximum Zener current IZM for JANS1N4117D-1/TR is 40 mA, derived from its 500 mW power rating and 25 V nominal Zener voltage (P = V × I). This value assumes operation at 25 °C ambient with appropriate thermal management; derating begins linearly at 50 °C and reaches zero at 175 °C, as specified in the JANS1N4117D-1/TR datasheet Figure 2.
How is polarity marked on JANS1N4117D-1/TR?
JANS1N4117D-1/TR uses a single black cathode band on the glass body to indicate polarity. During Zener regulation, the banded end is the cathode and must be held at a higher potential than the unbanded (anode) end. This marking is laser-etched and verified per MIL-STD-750 Method 2015, ensuring unambiguous identification throughout JANS1N4117D-1/TR handling and soldering.
