Product details
Overview
JANS1N4109D-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 JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 100 Ω dynamic impedance, low noise density (1 µV/√Hz), and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4109D-1/TR datasheet, JANS1N4109D-1/TR pinout, JANS1N4109D-1/TR application, or JANS1N4109D-1/TR equivalent, key selection criteria include its 1% Zener voltage tolerance, JANS-level radiation-hardened qualification, DO-35 mechanical robustness, and verified noise performance below 1 µV/√Hz at 15 V - critical for precision reference and space-grade power conditioning circuits.
Technical Context
This device functions as a two-terminal shunt voltage regulator operating in reverse breakdown. Its metallurgical bond construction ensures long-term stability under thermal cycling and ionizing radiation, supporting compliance with MIL-PRF-19500/435 JANS screening requirements including burn-in, temperature cycling, and hermeticity testing.
The JANS1N4109D-1/TR exhibits a positive temperature coefficient of +0.085 %/°C and maintains ≤0.05 µA reverse leakage at 12.0 V, enabling predictable drift compensation in analog reference chains. Its 100 Ω dynamic impedance at 250 mA ensures minimal output voltage variation over load current changes in regulated supply rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4109D-1 | Same electrical specs and DO-35 package; qualified to JANTXV level (not JANS), with reduced radiation hardness assurance and no Class S screening. | Limited to ground-based or non-spaceflight military systems requiring high reliability but not full space qualification. | Select when radiation hardness and extended temperature validation per MIL-PRF-19500/435 Annex G are not required. |
| 1N4109US-1TR | Same 15 V/1% spec but in surface-mount DO-213AA package; lacks JANS qualification and has higher thermal resistance (RθJA = 400 °C/W vs. 300 °C/W). | Suitable for commercial or industrial PCBs where automated assembly and board space are prioritized over hermetic sealing and extreme environment operation. | Select only for non-military, non-radiation environments where reflow compatibility and smaller footprint outweigh reliability requirements. |
Compared with JANTXV1N4109D-1 and 1N4109US-1TR, the JANS1N4109D-1/TR uniquely combines Class S radiation hardness, hermetic DO-35 packaging, and full MIL-PRF-19500/435 JANS screening - making it the sole choice for flight-critical voltage references where parameter stability under ionizing radiation and thermal stress is non-negotiable.

FAQ
What is the Zener voltage tolerance of JANS1N4109D-1/TR?
The JANS1N4109D-1/TR has a nominal Zener voltage of 15.0 V with a tight ±1% tolerance, indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range and validated during JANS-level screening. The 1% tolerance reduces calibration overhead in precision analog circuits where JANS1N4109D-1/TR serves as a primary reference.
Is JANS1N4109D-1/TR qualified for space applications?
Yes, JANS1N4109D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including radiation hardness assurance per Microsemi MicroNote 050. It meets Class S requirements for spaceflight use, with screening for total ionizing dose (TID), enhanced low-dose-rate sensitivity (ELDRS), and single-event effects (SEE) - making JANS1N4109D-1/TR appropriate for satellite and launch vehicle electronics.
What is the maximum reverse leakage current for JANS1N4109D-1/TR?
The maximum reverse leakage current (IR) for JANS1N4109D-1/TR is 0.05 µA at 12.0 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports low-power operation in battery-backed systems and ensures minimal error contribution in high-impedance reference networks where JANS1N4109D-1/TR is deployed.
Does JANS1N4109D-1/TR have low noise performance?
Yes, JANS1N4109D-1/TR delivers a maximum noise density of 1 µV/√Hz at 15 V and 250 mA, per Figure 1 and the Electrical Characteristics table. This performance is achieved through metallurgical bond construction and optimized doping profiles. For low-phase-noise oscillator designs or precision sensor excitation, JANS1N4109D-1/TR provides measurably cleaner bias than standard Zeners.
What package type does JANS1N4109D-1/TR use?
JANS1N4109D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package, with cathode identified by a band. The package dimensions comply with JEDEC standards and support manual or wave-solder assembly. The "TR" suffix indicates tape-and-reel packaging per EIA-296, confirming JANS1N4109D-1/TR is supplied in industry-standard reels for automated placement.
