Product details
Overview
JANTX1N4109D-1/TR from Microsemi is a 15.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supplies.
For engineers reviewing the JANTX1N4109D-1/TR datasheet, JANTX1N4109D-1/TR pinout, JANTX1N4109D-1/TR application, or JANTX1N4109D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (100 Ω at 250 mA), noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and MIL-qualified reliability level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 15.0 V at 250 mA test current (IZT), exhibiting a temperature coefficient of +0.085 %/°C and maximum reverse leakage of 0.05 µA at 12.0 V (VR). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The DO-35 package enables axial through-hole mounting with tin-lead plating, cathode band polarity marking, and hermetic glass sealing. It supports operation from –65 °C to +175 °C junction temperature, with linear power derating from 500 mW at 25 °C ambient to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.0 V ±1% at 250 mA - ensures tight regulation for reference circuits requiring <1% error budget. |
| Power Dissipation | 500 mW at 25 °C lead temp - supports stable operation in compact, conduction-cooled designs. |
| Dynamic Impedance (ZZT) | 100 Ω at IZT - low AC impedance minimizes output voltage variation under load transients. |
| Noise Density (ND) | 1 µV/√Hz at 250 mA - ultra-low broadband noise critical for precision analog references. |
| Temp Coefficient (αVZ) | +0.085 %/°C - predictable positive drift enables accurate temperature-compensated designs. |
| Reverse Leakage (IR) | 0.05 µA max at 12.0 V - negligible standby current preserves battery life in low-power systems. |
| Junction Temp Range | –65 °C to +175 °C - validated for extended-temperature military, avionics, and downhole electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4109US-1TR | Same 15.0 V, 1% spec, but in surface-mount DO-213AA package; no axial leads. | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or legacy board rework. | Select when space-constrained layouts or automated pick-and-place manufacturing demand SMT compatibility. |
| JAN1N4109D-1/TR | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX). | Lacks JANTX-level burn-in, lot acceptance testing, and failure analysis reporting required for mission-critical platforms. | Select only for non-safety-critical commercial/military hybrid applications where full JANTX documentation is not mandated. |
Compared with JANTX1N4109D-1/TR, the 1N4109US-1TR offers identical regulation performance in a smaller footprint but eliminates axial-leaded flexibility, while the JAN1N4109D-1/TR reduces cost and lead time at the expense of MIL-qualified reliability assurance for high-integrity systems.

FAQ
What is the Zener voltage tolerance of JANTX1N4109D-1/TR?
JANTX1N4109D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This means its nominal 15.0 V Zener voltage is guaranteed between 14.85 V and 15.15 V at 250 mA test current and 25 °C, enabling high-accuracy reference design without post-calibration.
Is JANTX1N4109D-1/TR RoHS compliant?
No, JANTX1N4109D-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4109D-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 to ensure solderability and reliability under military thermal cycling requirements.
What does the "TR" suffix mean in JANTX1N4109D-1/TR?
The "TR" suffix in JANTX1N4109D-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated assembly. It does not affect electrical or reliability specifications - the device remains identical to the bulk version except for packaging format and quantity per reel.
What is the maximum reverse leakage current for JANTX1N4109D-1/TR?
JANTX1N4109D-1/TR has a maximum reverse leakage current (IR) of 0.05 µA at VR = 12.0 V and 25 °C. This ultra-low leakage supports energy-efficient standby modes and high-impedance sensing circuits where parasitic current paths must be minimized.
How is the temperature coefficient of JANTX1N4109D-1/TR specified?
JANTX1N4109D-1/TR has a temperature coefficient (αVZ) of +0.085 %/°C, meaning its Zener voltage increases by approximately 12.75 mV per °C rise in junction temperature. This predictable positive drift allows designers to compensate for thermal effects in precision reference networks.
