Product details
Overview
JANS1N4103C-1/TR from Microsemi is a 500 mW, 9.1 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with ±2% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and 0.5 µA reverse leakage at 7.0 V. It serves as a precision voltage reference in radiation-hardened military power regulation and analog signal conditioning circuits.
For engineers reviewing the JANS1N4103C-1/TR datasheet, JANS1N4103C-1/TR pinout, JANS1N4103C-1/TR application, or JANS1N4103C-1/TR equivalent, this page delivers verified electrical specs, thermal derating behavior, noise density (1 µV/√Hz), and JANS-level qualification context for high-reliability design validation.
Technical Context
This device operates in reverse-biased Zener breakdown mode with a nominal 9.1 V regulation voltage at 250 mA test current (IZT), exhibiting +0.080 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT). Its metallurgically bonded glass construction ensures hermetic sealing and inherent radiation hardness per Microsemi MicroNote 050.
Rated for 500 mW average power dissipation at 25 °C lead temperature, it linearly derates to zero at 175 °C ambient, with junction-to-lead thermal resistance of 250 °C/W at 10 mm lead length. Reverse leakage is limited to 0.5 µA at VR = 7.0 V, and noise density is specified at 1 µV/√Hz - consistent with low-noise reference applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V ±2% at 250 mA - defines stable regulation point for precision biasing and reference generation |
| Power Dissipation | 500 mW @ TC = 25 °C - supports continuous operation in compact, unheatsinked layouts with linear derating above 50 °C |
| Dynamic Impedance | 200 Ω @ IZT = 250 mA - determines output voltage stability under load current variation |
| Reverse Leakage | 0.5 µA @ VR = 7.0 V - ensures minimal error contribution in high-impedance reference nodes |

| Temp Coefficient | +0.080 %/°C - quantifies drift magnitude over operating temperature range for system-level accuracy budgeting |
| Junction Temp Range | –65 to +175 °C - validated for extreme-environment deployment including space and avionics |
Pinout & Package

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4103C-1 | Same 9.1 V ±2%, DO-35 package, but qualified only to JANTXV level - lower screening rigor and no radiation hardness documentation | Limited to non-radiation environments; not approved for space or nuclear instrumentation | Select when full JANS qualification is unnecessary and cost sensitivity outweighs long-term reliability assurance |
| 1N4103C-1/TR | Commercial-grade version with RoHS-compliant matte-tin plating; identical electrical specs but no MIL-PRF-19500 qualification | Restricted to terrestrial industrial or commercial systems without environmental or reliability mandates | Choose for prototyping or volume production where JANS-level traceability and screening are not contractually required |

FAQ
What is the Zener voltage tolerance and test condition for JANS1N4103C-1/TR?
JANS1N4103C-1/TR has a nominal Zener voltage of 9.1 V with ±2% tolerance, measured at 250 mA Zener test current (IZT) and 25 °C ambient temperature. The "C" suffix explicitly denotes the 2% tolerance grade per JEDEC nomenclature, and this value is guaranteed under JANS-level screening and thermal equilibrium conditions.
Is JANS1N4103C-1/TR radiation hardened, and what documentation supports this claim?
Yes, JANS1N4103C-1/TR is inherently radiation hard per Microsemi MicroNote 050, a publicly archived technical note confirming its tolerance to total ionizing dose (TID) without parameter degradation. This property stems from its metallurgically bonded glass construction and is validated as part of JANS qualification per MIL-PRF-19500/435.
What is the maximum reverse leakage current specification for JANS1N4103C-1/TR?
JANS1N4103C-1/TR specifies a maximum reverse leakage current (IR) of 0.5 µA at VR = 7.0 V and 25 °C. This value is confirmed in the Electrical Characteristics table on Page 3 of T4-LDS-0245-2 Rev. 1 and applies to all JANS-level units post-screening.
Does JANS1N4103C-1/TR have a defined noise density, and how is it measured?
Yes, JANS1N4103C-1/TR has a noise density of 1 µV/√Hz, measured using a 1 kHz to 3 kHz bandpass filter at 25 °C ambient and constant IZT = 250 mA, per Figure 1 and associated notes in T4-LDS-0245-2. This low noise performance is retained across the JANS qualification lot.
What packaging and marking details apply to JANS1N4103C-1/TR?
JANS1N4103C-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by a visible band. It is marked with the full part number and supplied in tape-and-reel format (EIA-296 compliant) as denoted by the "TR" suffix; weight is approximately 0.2 grams.
