Product details
Overview
JAN1N4103D-1/TR from Microsemi is a 500 mW, 9.1 V, ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded 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/TR datasheet, JAN1N4103D-1/TR pinout, JAN1N4103D-1/TR application, or JAN1N4103D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.080 %/°C), and JANS-level radiation hardness.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 9.1 V at 250 mA test current (IZT), exhibiting low dynamic impedance (200 Ω) and minimal capacitance (typ. <2 pF). Its metallurgical bond construction ensures stable regulation across wide current (1–40 mA) and temperature (−65 °C to +175 °C) ranges.
The JAN1N4103D-1/TR delivers low-noise performance (1 µV/√Hz) and exhibits a positive temperature coefficient (+0.080 %/°C), enabling predictable drift compensation in reference circuits. It is hermetically sealed in glass and non-sensitive to ESD per MIL-STD-750 Method 1020.

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 | Required for automated SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and reflow compatibility is mandatory |
| JANTXV1N4103D | Identical Zener parameters and ±1% tolerance, but qualified only to JANTXV (not JANS); lower screening rigor | Acceptable for airborne (non-space) platforms where full JANS testing is not mandated by spec | Select when cost sensitivity outweighs requirement for Class S radiation assurance |
Compared with JAN1N4103D-1/TR, the 1N4103US-1 offers identical regulation performance in a surface-mount form factor, while JANTXV1N4103D provides a lower-cost alternative with reduced screening depth-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JAN1N4103D-1/TR?
JAN1N4103D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet, where it specifies 9.1 V nominal VZ at 250 mA with ±1% tolerance. The tighter tolerance reduces calibration overhead in high-accuracy reference designs compared to standard 5% variants like JAN1N4103-1.
Is JAN1N4103D-1/TR qualified to JANS level?
Yes, JAN1N4103D-1/TR is qualified to JANS level per MIL-PRF-19500/435, as explicitly stated in the "Qualified Levels" section on page 1 of the datasheet. This includes full Class S screening for space applications, such as radiation hardness assurance, extended temperature testing, and lot traceability-making it suitable for satellite and strategic defense systems where failure is not an option.
What is the maximum Zener current (IZM) for JAN1N4103D-1/TR?
The maximum Zener current (IZM) for JAN1N4103D-1/TR is 40 mA, as listed in the Electrical Characteristics table on page 3 of the datasheet. This value corresponds to the rated average power dissipation of 500 mW at 25 °C ambient, derived from P = VZ × IZM → 9.1 V × 40 mA ≈ 364 mW, with margin reserved for thermal derating above 50 °C per Figure 2.
Does JAN1N4103D-1/TR have low noise performance?
Yes, JAN1N4103D-1/TR delivers low noise performance with a specified noise density of 1 µV/√Hz at 250 mA test current, per the Electrical Characteristics table. This is among the lowest values in the 1N4100-series and results from optimized metallurgical bonding and low-capacitance glass packaging-critical for precision analog circuits such as metrology-grade references and low-phase-noise oscillator biasing.
What package type does JAN1N4103D-1/TR use?
JAN1N4103D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded glass package, as confirmed in the "MECHANICAL and PACKAGING" section on page 2 of the datasheet. It features hermetically sealed construction, tin-lead or RoHS-compliant matte-tin plating, and cathode identification via a visible band. The "TR" suffix indicates tape-and-reel packaging per EIA-296.
