Product details
Overview
JAN1N4109C-1 from Microsemi is a 500 mW, 15 V Zener voltage regulator diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and maximum reverse leakage of 0.05 µA at 12.8 V. It delivers stable regulation in high-reliability power supply reference and voltage clamp circuits for aerospace and defense systems.
For engineers reviewing the JAN1N4109C-1 datasheet, JAN1N4109C-1 pinout, JAN1N4109C-1 application, or JAN1N4109C-1 equivalent, key selection factors include its JANTXV qualification status, 15 V nominal Zener voltage with ±2% tolerance, 100 Ω Zener impedance at IZT = 250 mA, low 0.05 µA IR at VR = 12.8 V, and DO-35 axial-leaded hermetic glass package suitable for high-temperature and radiation-hardened environments.
Technical Context
This device operates as a precision shunt voltage reference using avalanche breakdown in a metallurgically bonded silicon junction. Its 15 V nominal Zener voltage exhibits +0.085 %/°C temperature coefficient and 1 µV/√Hz noise density at 25 °C, enabling low-noise analog references in regulated power supplies.
The JAN1N4109C-1 is rated for 500 mW average power dissipation with linear derating from 50 °C (ambient) to zero at 175 °C, and features thermal resistance of 250 °C/W junction-to-lead (3/8″ lead length), supporting operation in high-temperature military chassis-mounted applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4109UR-1 | Same electrical specs but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; no axial through-hole mounting | Select when automated assembly and board space reduction are prioritized over legacy through-hole compatibility |
| JANTXV1N4109-1 | Identical DO-35 package and 15 V rating but with ±5% tolerance (no C suffix) | Higher voltage variation requires tighter downstream filtering or calibration | Select when cost sensitivity outweighs need for ±2% regulation accuracy in non-critical rails |
Compared with JAN1N4109C-1, 1N4109UR-1 offers identical regulation performance in a surface-mount form factor ideal for modern high-density layouts, while JANTXV1N4109-1 provides the same military qualification at lower cost but with relaxed ±5% voltage tolerance requiring additional design margin.

FAQ
What is the Zener voltage tolerance of JAN1N4109C-1?
JAN1N4109C-1 has a nominal Zener voltage of 15.0 V with ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient temperature, and applies across the full qualified temperature range of -65 to +175 °C for JANTXV-level devices.
Is JAN1N4109C-1 suitable for surface-mount assembly?
No, JAN1N4109C-1 uses the axial-leaded DO-35 (DO-204AH) glass package and is intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the 1N4109UR-1 in DO-213AA package - a functionally identical part with same 15 V Zener voltage and JANTXV qualification but adapted for reflow soldering.
What is the maximum reverse leakage current for JAN1N4109C-1?
JAN1N4109C-1 specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 12.8 V, measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and minimizes quiescent power loss in battery-backed or low-power subsystems where JAN1N4109C-1 serves as a reference element.
Does JAN1N4109C-1 meet RoHS requirements?
No, JAN1N4109C-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4109C-1e3); military-qualified parts like JAN1N4109C-1 retain tin-lead plating per MIL-STD-750 and are exempt from RoHS compliance requirements due to their high-reliability application scope.
What is the thermal resistance specification for JAN1N4109C-1?
JAN1N4109C-1 has a thermal resistance of 250 °C/W junction-to-lead (RθJL) when mounted with 3/8″ (10 mm) lead length from body, and 300 °C/W junction-to-ambient (RθJA) on FR4 board with specified copper pad geometry. These values govern safe power derating - JAN1N4109C-1 must be linearly derated from 500 mW starting at 50 °C lead temperature to zero at 175 °C.
