Product details
Overview
JAN1N4103C-1/TR from Microsemi is a 500 mW, 9.1 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, low 0.5 µA reverse leakage at 7.0 V, and +0.080 %/°C temperature coefficient - used in precision reference and power supply feedback circuits for aerospace and defense systems.
For engineers reviewing the JAN1N4103C-1/TR datasheet, JAN1N4103C-1/TR pinout, JAN1N4103C-1/TR application, or JAN1N4103C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), MIL-qualified reliability level (JAN), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and DO-35 mechanical compatibility with legacy through-hole designs.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures high-reliability performance under thermal cycling and radiation exposure, supporting operation from –65 °C to +175 °C junction temperature.
It exhibits 200 Ω dynamic impedance at 250 mA Zener test current and maintains ≤0.5 µA reverse leakage at VR = 7.0 V, enabling stable regulation across wide current ranges without external compensation. The +0.080 %/°C temperature coefficient is optimized for mid-voltage references where drift must be minimized in unregulated environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same 9.1 V ±2%, but in DO-213AA surface-mount package; no axial leads. | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or legacy repair. | Select when board space is constrained and reflow capability exists; not drop-in compatible. |
| JAN1N4103D-1/TR | Identical electrical specs except ±1% Zener tolerance (D suffix); same JAN qualification and DO-35 package. | Used where tighter initial accuracy is required, e.g., metrology-grade calibration standards. | Choose for highest initial precision; adds cost but eliminates trim resistors in critical references. |
Compared with JAN1N4103C-1/TR, 1N4103US-1 offers footprint reduction at the expense of mechanical mounting flexibility, while JAN1N4103D-1/TR trades tighter tolerance for higher unit cost - both require explicit validation against the target application's accuracy, layout, and qualification requirements.

FAQ
What is the Zener voltage tolerance of JAN1N4103C-1/TR?
JAN1N4103C-1/TR has a nominal Zener voltage of 9.1 V with a tolerance of ±2%, indicated by the "C" suffix in the part number. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when used within its power and thermal limits.
Is JAN1N4103C-1/TR suitable for space applications?
Yes, JAN1N4103C-1/TR is qualified to JAN level per MIL-PRF-19500/435 and features inherent radiation hardness per Microsemi MicroNote 050. Its hermetic DO-35 package and metallurgical bond construction support use in LEO and GEO satellite power systems where TID tolerance and thermal stability are mandatory.
What is the maximum reverse leakage current for JAN1N4103C-1/TR?
The maximum reverse leakage current (IR) for JAN1N4103C-1/TR is 0.5 µA at VR = 7.0 V and 25 °C. This value remains stable across the full qualified temperature range and is critical for minimizing error in high-impedance reference networks using JAN1N4103C-1/TR.
Does JAN1N4103C-1/TR have RoHS compliance?
No, JAN1N4103C-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (blank reliability level). JAN-level parts like JAN1N4103C-1/TR use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS under defense procurement waivers.
What is the thermal resistance junction-to-lead for JAN1N4103C-1/TR?
JAN1N4103C-1/TR has a thermal resistance of 250 °C/W junction-to-lead when measured with 3/8 inch (10 mm) lead length from body. This value enables accurate thermal modeling in chassis-mounted or heatsink-attached configurations where lead conduction dominates cooling.
