Product details
Overview
JANS1N4109C-1/TR from Microsemi is a hermetically sealed, metallurgically bonded glass Zener diode in DO-35 package, rated for 500 mW power dissipation, with nominal Zener voltage of 15.0 V at 250 mA test current, ±2% tolerance (denoted by "C"), and qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications.
For engineers reviewing the JANS1N4109C-1/TR datasheet, JANS1N4109C-1/TR pinout, JANS1N4109C-1/TR application, or JANS1N4109C-1/TR equivalent, key selection criteria include its 15.0 V regulation accuracy, low dynamic impedance (100 Ω), minimal reverse leakage (0.05 µA @ 11.4 V), radiation-hardened construction, and thermal stability across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision voltage reference and shunt regulator in high-stability analog circuits, leveraging metallurgical bonding for low noise (1 µV/√Hz typical) and stable Zener knee characteristics. Its internal construction ensures immunity to ESD per MIL-STD-750 Method 1020 and inherent radiation hardness per Microsemi MicroNote 050.
The JANS1N4109C-1/TR exhibits a positive temperature coefficient of +0.085 %/°C, enabling predictable drift compensation in temperature-critical bias networks. It maintains regulation over wide current ranges (IZK to IZM = 11.4 mA to 40 mA) and supports stable operation up to 175 °C junction temperature with linear derating from 500 mW at 25 °C ambient.
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 surface-mount DO-213AA package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or repair | Select when board-level automation and space constraints outweigh manual serviceability needs |
| JANTXV1N4109C-1 | Identical Zener parameters and DO-35 package, but qualified only to JANTXV level (not JANS) | Lacks full space-grade screening (e.g., radiation lot acceptance testing); limited to non-flight subsystems | Choose for ground-test equipment or avionics spares where JANS cost premium is unjustified |
Compared with JANS1N4109C-1/TR, the 1N4109US-1 enables higher-density layouts but sacrifices hand-solderability, while JANTXV1N4109C-1 reduces procurement cost and lead time at the expense of radiation assurance and extended life testing required for flight hardware.

FAQ
What is the Zener voltage tolerance of JANS1N4109C-1/TR?
The "C" suffix in JANS1N4109C-1/TR denotes ±2% Zener voltage tolerance at 250 mA test current, verified per MIL-PRF-19500/435 screening. This tighter tolerance than standard ±5% parts enables higher-accuracy reference design in precision analog circuits without external trimming.
Is JANS1N4109C-1/TR suitable for space applications?
Yes - JANS1N4109C-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including radiation lot acceptance testing and extended life screening. Its inherent radiation hardness per MicroNote 050 makes it appropriate for low-earth orbit satellite subsystems where TID resistance up to 100 krad(Si) is required.
What is the maximum reverse leakage current for JANS1N4109C-1/TR?
JANS1N4109C-1/TR has a maximum reverse leakage current (IR) of 0.05 µA at 11.4 V (0.76 × VZ), measured at 25 °C. This ultra-low leakage preserves accuracy in high-impedance bias networks and minimizes power loss in battery-powered remote sensors.
Does JANS1N4109C-1/TR require derating above 25 °C ambient?
Yes - JANS1N4109C-1/TR's 500 mW power rating linearly derates from 25 °C ambient to zero at 175 °C junction temperature. At 100 °C ambient, maximum allowable dissipation drops to ~330 mW, requiring careful thermal design in enclosed avionics enclosures.
What packaging option does the "TR" suffix indicate for JANS1N4109C-1/TR?
The "TR" suffix on JANS1N4109C-1/TR indicates tape-and-reel packaging per EIA-296 standard, optimized for automated pick-and-place assembly. Each reel contains standard quantities per factory specification and supports high-volume production of military-grade PCBs.
