Product details
Overview
JANTXV1N4109C-1 from Microsemi is a 15 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4109C-1 datasheet, JANTXV1N4109C-1 pinout, JANTXV1N4109C-1 application, or JANTXV1N4109C-1 equivalent, key selection criteria include Zener voltage (15.0 V), test current (250 mA), dynamic impedance (100 Ω), temperature coefficient (+0.085 %/°C), and hermetic DO-35 packaging for stable operation across -65 °C to +175 °C.
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, exhibiting low dynamic impedance (100 Ω) and minimal noise density (1 µV/√Hz). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The JANTXV1N4109C-1 is rated for 500 mW average power dissipation with linear derating above 50 °C lead temperature, and features cathode band polarity marking for unambiguous orientation in series-shunt regulation circuits requiring tight voltage reference stability.
Key Specifications

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 | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when automated assembly and board space constraints outweigh need for axial mounting flexibility |
| JANS1N4109C-1 | Identical electrical and mechanical specs, but qualified to JANS (highest MIL-PRF-19500 reliability level) with full radiation testing | Required for spaceflight and nuclear-hardened systems where single-event burnout (SEB) immunity is mandated | Select only when JANS-level screening and radiation assurance documentation are contractually required |
Compared with JANTXV1N4109C-1, the 1N4109US-1 trades axial-mount robustness for SMT compatibility, while JANS1N4109C-1 adds radiation hardness verification at higher cost and longer lead time-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JANTXV1N4109C-1?
JANTXV1N4109C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a nominal 15.0 V Zener voltage ranging from 14.7 V to 15.3 V at 250 mA test current and 25 °C ambient, enabling tighter regulation than standard 5% tolerance variants.
Is JANTXV1N4109C-1 suitable for high-temperature operation?
Yes, JANTXV1N4109C-1 is rated for junction and storage temperatures from -65 °C to +175 °C and is qualified to MIL-PRF-19500/435 JANTXV level. Its metallurgically bonded construction and hermetic DO-35 package ensure stable Zener voltage and low leakage across this full range, making it suitable for engine bay or avionics bay deployments.
What does the "JANTXV" prefix indicate for JANTXV1N4109C-1?
The "JANTXV" prefix on JANTXV1N4109C-1 signifies compliance with the highest commercial-off-the-shelf (COTS) military reliability level defined in MIL-PRF-19500/435-exceeding JAN and JANTX in screening rigor and including additional environmental stress testing such as thermal shock and life testing.
Does JANTXV1N4109C-1 have low noise performance?
Yes, JANTXV1N4109C-1 exhibits a maximum noise density of 1 µV/√Hz at its 15 V Zener voltage and 250 mA test current. This low-noise characteristic is confirmed in Microsemi's T4-LDS-0245-2 datasheet and makes JANTXV1N4109C-1 appropriate for precision analog references where spectral purity is critical.
What is the maximum Zener current rating for JANTXV1N4109C-1?
JANTXV1N4109C-1 has a maximum Zener current (IZM) of 40 mA, derived from its 500 mW power rating and 15 V nominal Zener voltage (P = V × I → I = 0.5 W / 15 V ≈ 33.3 mA, rounded to 40 mA per datasheet Table on Page 3). Operation beyond this current risks thermal runaway or parametric shift.
