Product details
Overview
JAN1N4109D-1/TR from Microsemi is a 15 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 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 JAN1N4109D-1/TR datasheet, JAN1N4109D-1/TR pinout, JAN1N4109D-1/TR application, or JAN1N4109D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (100 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.085 %/°C), and JANS-level radiation hardness.
Technical Context
This device operates as a precision shunt regulator with a nominal Zener voltage of 15.0 V at 250 mA test current, exhibiting low dynamic impedance (100 Ω) and minimal capacitance (typ. 40 pF). Its metallurgical bond construction ensures stable breakdown characteristics across temperature extremes.
Designed for high-reliability environments, it delivers ±1% initial voltage tolerance, +0.085 %/°C temperature coefficient, and maintains regulation over wide current ranges (IZK to IZM = 7.6 mA to 40 mA) while meeting MIL-STD-750 ESD immunity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 15.0 V ±1% @ 250 mA - enables precise reference generation in regulated power supplies requiring tight voltage stability. |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous operation in compact, unheatsinked designs with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 100 Ω @ 250 mA - ensures minimal output voltage variation under load transients in feedback reference circuits. |
| Noise Density | 1 µV/√Hz @ 250 mA - critical for low-noise analog references in precision instrumentation and ADC biasing. |
| Temp. Coefficient αVZ | +0.085 %/°C - provides predictable, monotonic voltage drift over -65 °C to +175 °C operating range. |
| Reverse Leakage IR | 0.05 µA @ 12.0 V - guarantees negligible current draw in standby mode for battery-backed systems. |
| Capacitance | 40 pF (typ.) - minimizes high-frequency coupling in RF bias networks and fast-switching regulators. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode indicated by band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or common return path; establishes reference potential for Zener regulation. |
| Cathode | Regulated output node | Banded end carries stabilized 15 V output; must be biased positive relative to anode for breakdown operation. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANS qualification | Validated for space-grade applications with full radiation hardness data per MicroNote 050. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling, ensuring long-term parameter stability. |
| 1% Zener voltage tolerance | Reduces need for post-assembly trimming in precision voltage references and calibration circuits. |
| Low noise density (1 µV/√Hz) | Supports use in high-resolution analog front-ends where reference noise directly impacts SNR. |
| Hermetic glass sealing | Prevents moisture ingress and parametric shift in humid or corrosive environments (e.g., avionics bays). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4109US-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 repair. | Select when board space is constrained and reflow compatibility is mandatory. |
| JANTXV1N4109D-1 | Identical Zener parameters and 1% tolerance, but qualified only to JANTXV (not JANS) per MIL-PRF-19500/435. | Approved for high-reliability ground systems but not spaceflight; lower radiation hardness validation. | Select when JANS-level radiation testing is not required and cost sensitivity is higher. |
Compared with JAN1N4109D-1/TR, 1N4109US-1 offers identical regulation performance in a smaller footprint but lacks axial mounting flexibility, while JANTXV1N4109D-1 reduces procurement cost and lead time at the expense of full space-grade qualification.

FAQ
What is the Zener voltage tolerance of JAN1N4109D-1/TR?
JAN1N4109D-1/TR has a nominal Zener voltage of 15.0 V with a ±1% tolerance, as indicated by the "D" suffix in its nomenclature per Microsemi's part numbering system. This tight tolerance is verified at 250 mA test current and ensures minimal binning or calibration effort in precision reference designs.
Is JAN1N4109D-1/TR suitable for space applications?
Yes, JAN1N4109D-1/TR is qualified to JANS level per MIL-PRF-19500/435 and documented as inherently radiation hard per Microsemi MicroNote 050, making it suitable for low-Earth orbit satellite systems where total ionizing dose and single-event effects must be mitigated.
What is the maximum Zener current IZM for JAN1N4109D-1/TR?
The maximum Zener current IZM for JAN1N4109D-1/TR is 40 mA, derived from its 500 mW power rating and 15 V Zener voltage (P = V × I). This value is specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet.
Does JAN1N4109D-1/TR have RoHS compliance?
No, JAN1N4109D-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4109D-1e3); JAN-level parts like JAN1N4109D-1/TR retain tin-lead plating per MIL-STD-750 for enhanced solderability and reliability in high-reliability assemblies.
What is the thermal resistance junction-to-lead for JAN1N4109D-1/TR?
The thermal resistance junction-to-lead (RθJL) for JAN1N4109D-1/TR is 250 °C/W when measured with 3/8 inch (10 mm) lead length from the body, as specified in the Maximum Ratings table on page 1 of the T4-LDS-0245-2 datasheet.
