Product details
Overview
JANTXV1N4109C-1/TR from Microsemi is a 15 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANTXV level per MIL-PRF-19500/435, used for precision voltage regulation in military power supplies and analog reference circuits.
For engineers reviewing the JANTXV1N4109C-1/TR datasheet, JANTXV1N4109C-1/TR pinout, JANTXV1N4109C-1/TR application, or JANTXV1N4109C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), low noise density (1 µV/√Hz), radiation-hardened construction, and MIL-spec thermal derating behavior.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 15.0 V at 250 mA test current, dynamic impedance of 200 Ω, and temperature coefficient of +0.080 %/°C. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
Designed for high-reliability environments, it delivers regulated output across wide current ranges (IZK to IZM) while maintaining ≤0.05 µA reverse leakage at VR = 12.0 V and exhibiting minimal capacitance (<2 pF typical at 15 V), critical for low-noise analog references and stable bias networks.

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 DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated SMT placement is available |
| JANTXV1N4109D-1/TR | Identical package and rating but tighter ±1% Zener tolerance (D suffix) | Higher cost; justified only where absolute voltage accuracy > ±0.15 V is mandatory | Select only if system-level calibration budget requires sub-1% initial tolerance |
Compared with JANTXV1N4109C-1/TR, the 1N4109US-1 offers identical regulation performance in a compact SMT form factor but eliminates manual lead forming, while JANTXV1N4109D-1/TR trades higher cost for ±1% tolerance-valuable only in metrology-grade references where 0.15 V margin is insufficient.

FAQ
What is the Zener voltage tolerance of JANTXV1N4109C-1/TR?
JANTXV1N4109C-1/TR has a nominal Zener voltage of 15.0 V with a tolerance of ±2%, denoted by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range and qualifies the device for precision regulation tasks where tighter control than standard ±5% parts is required.
Is JANTXV1N4109C-1/TR radiation hardened?
Yes, JANTXV1N4109C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide proven resistance to total ionizing dose (TID), making it suitable for satellite, avionics, and nuclear instrumentation applications without requiring additional shielding or derating.
What is the maximum reverse leakage current for JANTXV1N4109C-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4109C-1/TR is 0.05 µA at VR = 12.0 V and 25 °C. This ultra-low leakage ensures minimal power loss and stable reference behavior in high-impedance bias networks, especially critical in battery-powered or low-quiescent-current military subsystems.
Does JANTXV1N4109C-1/TR require derating above 25 °C?
Yes, JANTXV1N4109C-1/TR must be linearly derated starting at 25 °C ambient (on a typical PCB) or 50 °C lead temperature, reaching zero power dissipation at 175 °C. The derating slope is 5.88 mW/°C (500 mW over 85 °C), per Figure 2 in the official datasheet T4-LDS-0245-2.
What does the "TR" suffix mean in JANTXV1N4109C-1/TR?
The "TR" suffix in JANTXV1N4109C-1/TR indicates tape-and-reel packaging per EIA-296 standards, enabling automated pick-and-place assembly. It does not affect electrical or reliability specifications - the device remains fully compliant with MIL-PRF-19500/435 JANTXV requirements and retains all stated performance parameters.
