Product details
Overview
JAN1N4103D-1 from Microsemi is a 500 mW, 9.1 V, ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4103D-1 datasheet, JAN1N4103D-1 pinout, JAN1N4103D-1 application, or JAN1N4103D-1 equivalent, key selection criteria include its 9.1 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.5 µA maximum reverse leakage at 7.0 V, and radiation-hardened hermetic construction suitable for harsh-environment analog reference and overvoltage protection circuits.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK = 250 mA and exhibits low noise density (1 µV/√Hz typical) due to its metallurgical bond structure. Its temperature coefficient of +0.080 %/°C ensures stable regulation across -65 °C to +175 °C junction range.
The JAN1N4103D-1 is designed for operation with cathode band positive relative to anode, requiring no series resistor in low-current reference applications but supporting up to 75 mA maximum Zener current (IZM) under derated thermal conditions at TC = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 9.1 V at 250 mA test current - sets precise regulation point for feedback loops and reference rails. |
| Zener Tolerance | ±1% - enables tight voltage control without post-calibration in critical analog systems. |
| Max Dynamic Impedance (ZZT) | 200 Ω at 250 mA - limits output voltage variation under load transients in regulated supplies. |
| Max Reverse Leakage (IR) | 0.5 µA at 7.0 V - ensures minimal quiescent current draw in battery-backed or low-power sensing nodes. |
| Power Dissipation (PM(AV)) | 500 mW at TC = 25 °C - supports robust regulation in compact through-hole designs with adequate heatsinking. |
| Junction Temperature Range | -65 °C to +175 °C - validated for operation in extended-temperature military avionics and space-grade electronics. |
| Noise Density (ND) | 1 µV/√Hz - provides ultra-low-noise reference for precision ADCs and instrumentation amplifiers. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with hermetically sealed body, tin-lead or RoHS-compliant matte-tin plating, cathode indicated by black band. Total weight ≈ 0.2 g; lead length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or common return; must be at lower potential than cathode during regulation. |
| Cathode | Regulated output node | Banded end; supplies stable 9.1 V to load when reverse-biased above breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Eliminates interfacial voids and enhances long-term stability under thermal cycling and radiation exposure. |
| JANS-level qualification | Fully screened per MIL-PRF-19500/435 for use in mission-critical flight control and satellite power systems. |
| Low noise density | 1 µV/√Hz at 9.1 V enables clean voltage references in high-resolution data acquisition front-ends. |
| Radiation hardness | Inherently radiation-tolerant per Microsemi MicroNote 050 - suitable for low-dose-rate space environments without shielding. |
| Hermetic glass seal | Prevents moisture ingress and parameter drift over decades in sealed enclosures and vacuum assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-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 mechanical mounting. | Select when board space is constrained and automated placement is available. |
| JANTXV1N4103D | Identical Zener voltage, tolerance, and package; differs only in screening level (JANTXV vs JANS). | Lower screening depth - not approved for Class S space applications or nuclear-hardened systems. | Select for high-reliability ground-based radar or naval systems where full JANS is not mandated. |
Compared with JAN1N4103D-1, 1N4103US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-solderability, while JANTXV1N4103D delivers matching electrical behavior with reduced test coverage and lifecycle traceability for cost-sensitive defense programs.

FAQ
What is the Zener voltage and tolerance of JAN1N4103D-1?
JAN1N4103D-1 has a nominal Zener voltage of 9.1 V with ±1% tolerance at 250 mA test current (IZT), verified per MIL-PRF-19500/435 screening. This tight tolerance eliminates need for external trimming in precision reference designs and ensures consistent regulation across production lots.
Is JAN1N4103D-1 suitable for space applications?
Yes, JAN1N4103D-1 is JANS-qualified per MIL-PRF-19500/435 and inherently radiation-hard per Microsemi MicroNote 050, making it suitable for low-earth orbit and deep-space missions where single-event effects and total ionizing dose must be mitigated without additional shielding.
What is the maximum reverse leakage current for JAN1N4103D-1?
JAN1N4103D-1 specifies a maximum reverse leakage current (IR) of 0.5 µA at VR = 7.0 V, measured at 25 °C. This ultra-low leakage supports energy-efficient operation in battery-powered avionics subsystems and extends operational life in always-on monitoring circuits.
Does JAN1N4103D-1 require a series current-limiting resistor?
JAN1N4103D-1 can operate without a series resistor in low-current reference applications (<1 mA), but for full 500 mW dissipation, a resistor must limit current to ≤75 mA at worst-case input voltage. Thermal derating applies linearly from 500 mW at 25 °C to zero at 175 °C junction temperature.
What package type does JAN1N4103D-1 use?
JAN1N4103D-1 uses the DO-35 (DO-204AH) axial-leaded glass package with hermetic seal, cathode identified by black band, and tin-lead or RoHS-compliant matte-tin plating. Dimensions comply with MIL-STD-1835 and JEDEC outline DO-35.
