Product details
Overview
JAN1N4109-1/TR from Microsemi is a 15.0 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JAN level per MIL-PRF-19500/435, with 5% voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and 0.05 µA maximum reverse leakage at 12.0 V. It serves as a precision voltage reference in military-grade power supply regulation.
For engineers reviewing the JAN1N4109-1/TR datasheet, JAN1N4109-1/TR pinout, JAN1N4109-1/TR application, or JAN1N4109-1/TR equivalent, key selection criteria include Zener voltage stability over temperature, low noise density (≤1 µV/√Hz below 6.8 V), metallurgical bond reliability, and MIL-qualified thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded construction ensures stable Zener voltage under thermal cycling and radiation exposure, supporting high-reliability aerospace and defense systems.
It exhibits a +0.085 %/°C temperature coefficient and delivers regulated output across 10.7–11.4 mA Zener current range while maintaining ≤100 Ω dynamic impedance - critical for low-drift analog references and feedback networks in regulated DC-DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 15.0 V ±5% at 250 mA - defines nominal regulation point with predictable deviation in military-grade power rails |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - sets maximum continuous thermal load on PCB traces |
| Dynamic Impedance ZZT | 100 Ω at IZT = 250 mA - determines output voltage variation under load transients |
| Reverse Leakage IR | 0.05 µA max at VR = 12.0 V - ensures minimal quiescent current in standby-mode references |
| Noise Density | ≤1 µV/√Hz - enables use in low-noise analog circuits such as sensor excitation and precision ADC references |
| Temp Coefficient αVZ | +0.085 %/°C - quantifies voltage drift per degree, enabling thermal error budgeting in sealed enclosures |
| Junction Temp Range | −65 to +175 °C - supports operation in extreme environmental conditions without parameter shift |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-glass package with tin-lead plating; cathode identified by single black band; weight ≈0.2 g; lead length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to system ground or lower-potential rail; must sink full Zener current during regulation |
| Cathode (banded end) | Regulated output node | Held at stable 15.0 V relative to anode; supplies bias to op-amp inputs or feedback dividers |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock, ensuring long-term Zener voltage stability in flight-critical hardware |
| MIL-PRF-19500/435 JAN qualification | Validated screening for burn-in, temperature cycling, and hermeticity - required for DoD procurement compliance |
| Low noise density (≤1 µV/√Hz) | Reduces RMS noise contribution in high-gain analog stages, preserving signal integrity in radar receiver bias networks |
| Hermetic glass sealing | Prevents moisture ingress and ion migration, maintaining specified leakage and impedance over 20+ year field life |
| Non-ESD-sensitive design | Withstands >4 kV HBM per MIL-STD-750 Method 1020 - simplifies handling in uncontrolled assembly environments |

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 SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is available |
| JANTXV1N4109-1 | Identical DO-35 package and Zener parameters, but qualified to JANTXV level with extended screening (e.g., 100% lot testing) | Required for mission-critical avionics where failure probability must be <10−6 per hour | Select when system safety integrity level (ASIL-D or DAL-A) mandates enhanced reliability screening |
Compared with JAN1N4109-1/TR, 1N4109US-1 offers footprint reduction at the cost of mechanical robustness, while JANTXV1N4109-1 adds screening rigor without altering electrical behavior - enabling trade-offs between cost, manufacturability, and assurance level.

FAQ
What is the Zener voltage tolerance for JAN1N4109-1/TR?
JAN1N4109-1/TR has a nominal Zener voltage of 15.0 V with a ±5% tolerance, consistent with JEDEC-standardized 1N4099–1N4135 series specifications. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Does JAN1N4109-1/TR require heatsinking in typical applications?
JAN1N4109-1/TR does not require external heatsinking when operated within its 500 mW power limit and derated linearly above 50 °C lead temperature. Its RθJL of 250 °C/W allows safe operation at full power with 3/8-inch lead length on standard FR4 boards, provided ambient temperature remains below 70 °C.
Is JAN1N4109-1/TR RoHS compliant?
No, JAN1N4109-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS-compliant versions, which are only available for commercial-grade parts. JAN-level devices like JAN1N4109-1/TR use traditional tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS restrictions under defense procurement exemptions.
What is the maximum reverse leakage current for JAN1N4109-1/TR?
JAN1N4109-1/TR specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 12.0 V and 25 °C. This ultra-low leakage ensures minimal loading on high-impedance reference nodes and supports battery-powered applications with multi-year standby life.
How is polarity marked on JAN1N4109-1/TR?
JAN1N4109-1/TR uses a single black band to identify the cathode terminal. For proper Zener regulation, the banded end must be held at a higher potential than the unbanded (anode) end. This marking conforms to JEDEC DO-35 package standards and is visible under 10× magnification for automated optical inspection.
