Product details
Overview
JAN1N4103-1/TR from Microsemi is a 500 mW, 9.1 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supplies.
For engineers reviewing the JAN1N4103-1/TR datasheet, JAN1N4103-1/TR pinout, JAN1N4103-1/TR application, or JAN1N4103-1/TR equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 250 °C/W), noise density (1 µV/√Hz), junction temperature range (–65 to +175 °C), and MIL-spec qualification level.
Technical Context
This device operates as a precision shunt regulator with a nominal Zener voltage of 9.1 V at 250 mA test current (IZT), dynamic impedance of 200 Ω at IZT, and reverse leakage current ≤0.5 µA at 7.0 V (VR). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
It exhibits a positive temperature coefficient of +0.080 %/°C and low capacitance (typ. <1.5 pF), making it suitable for low-noise reference and stabilization circuits where voltage drift and parasitic coupling must be minimized across –65 to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.1 V ±5% at 250 mA - defines precise regulation point for feedback loops and reference rails |
| Power Dissipation | 500 mW at TL = 25 °C - supports stable operation in compact through-hole layouts with 3/8″ lead length |
| Dynamic Impedance ZZT | 200 Ω at IZT - limits output voltage variation under load transients in regulated supplies |
| Noise Density | 1 µV/√Hz - enables use in low-noise analog references without added filtering |
| Junction Temp Range | –65 to +175 °C - certified for extended-temperature military avionics and space-qualified subsystems |
| Thermal Resistance RθJL | 250 °C/W - determines safe derating curve when mounted with 10 mm lead length from body |
| Reverse Leakage IR | ≤0.5 µA at 7.0 V - ensures minimal quiescent current in standby or battery-backed circuits |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-glass package with cathode indicated by band; leads are tin-lead plated and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |

| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and vibration, ensuring long-term Zener voltage stability |
| Low noise density (1 µV/√Hz) | Reduces RMS noise contribution in precision voltage references without external filtering components |
| Hermetic glass sealing | Prevents moisture ingress and parameter drift in high-humidity or sealed enclosure environments |
| ESD immunity (MIL-STD-750 Method 1020) | Withstands >4 kV HBM without parameter shift-critical for handling in cleanroom and field-repair workflows |

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 repair | Select when board space is constrained and automated placement is available |
| JANTX1N4103-1 | Identical DO-35 package and Zener parameters, but qualified to JANTX level (higher screening than JAN) | Supports systems requiring enhanced burn-in and parametric testing per MIL-PRF-19500/435 Table I | Select when procurement mandates JANTX-level reliability documentation and lot traceability |
Compared with JAN1N4103-1/TR, 1N4103US-1 offers footprint reduction at the cost of manual assembly compatibility, while JANTX1N4103-1 adds screening rigor without altering electrical behavior-enabling trade-offs between cost, manufacturability, and assurance level.

FAQ
What is the Zener voltage tolerance for JAN1N4103-1/TR?
JAN1N4103-1/TR has a nominal Zener voltage of 9.1 V with a standard tolerance of ±5%, as defined in the JEDEC-registered 1N4099–1N4135 family specification and confirmed in the T4-LDS-0245-2 datasheet Electrical Characteristics table.
Is JAN1N4103-1/TR RoHS compliant?
No, JAN1N4103-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4103-1e3); JAN-level parts retain tin-lead plating per MIL-STD-750 and are exempt from RoHS restrictions under defense procurement rules.
What does the "TR" suffix mean in JAN1N4103-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4103-1/TR is supplied in reels containing standard quantities specified by Microsemi's factory-distinct from bulk or ammo-pack options.
What is the maximum Zener test current IZT for JAN1N4103-1/TR?
JAN1N4103-1/TR is characterized at a Zener test current IZT of 250 mA, as documented in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This current establishes the 9.1 V regulation point and is used for measuring ZZT and ND parameters.
How does JAN1N4103-1/TR differ from commercial 1N4103-1?
JAN1N4103-1/TR is screened and qualified to MIL-PRF-19500/435 JAN level-including temperature cycling, hermeticity, and parametric testing-whereas commercial 1N4103-1 lacks military screening and traceability. Both share identical electrical specs and DO-35 packaging, but JAN1N4103-1/TR carries full lot-level documentation required for defense contracts.
