Product details
Overview
JANS1N6109US/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon Zener diode rated for 15 V nominal breakdown voltage, 500 mW power dissipation, and ±5% voltage tolerance, designed for precision voltage regulation and transient suppression in aerospace-grade analog signal conditioning circuits.
For engineers reviewing the JANS1N6109US/TR datasheet, JANS1N6109US/TR pinout, JANS1N6109US/TR application, or JANS1N6109US/TR equivalent, key selection criteria include MIL-PRF-19500/537 qualification, hermetic TO-236AB (SOT-23) package, low dynamic impedance (≤20 Ω), temperature coefficient of ±0.05 %/°C, and radiation hardness up to 100 krad(Si).
Technical Context
This device operates as a two-terminal voltage reference with stable reverse-bias Zener conduction. It meets Class K screening per MIL-PRF-19500 and supports operation from –65 °C to +175 °C with guaranteed Zener voltage drift ≤±2.5% over full temperature range.
The JANS1N6109US/TR exhibits low noise spectral density (≤10 µV/√Hz at 1 kHz), minimal leakage current (≤100 nA at 12 V), and is qualified for use in high-reliability analog front-ends where long-term parametric stability under thermal cycling and ionizing radiation is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±5% - defines regulated output voltage under specified test current (5 mA) |
| Power Dissipation (PZ) | 500 mW - maximum continuous power handling in derated conditions up to +175 °C |
| Dynamic Impedance (ZZT) | ≤20 Ω at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Temperature Coefficient | ±0.05 %/°C - guarantees predictable VZ drift across military temperature range |
| Leakage Current (IR) | ≤100 nA at 12 V - enables low-error biasing in high-impedance sensor interfaces |

Pinout & Package
Hermetic TO-236AB (SOT-23) package with three terminals: Anode, Cathode, and case-connected substrate (non-functional for this diode). The JANS1N6109US/TR uses a two-terminal configuration; terminal 3 is internally tied to cathode and serves as mechanical ground anchor.

|---|---|---|
| Terminal 1 | Anode | Connected to circuit ground or lower-potential node during Zener operation |
| Terminal 2 | Cathode | Output node delivering regulated 15 V when reverse-biased above breakdown |
| Terminal 3 | Case / Substrate | Hermetically sealed metal tab tied to cathode; provides EMI shielding and thermal path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6109US | Same Zener voltage and screening level, but non-hermetic glass-passivated DO-35 package | Limited to non-vacuum, non-harsh-environment terrestrial systems | Choose for cost-sensitive ground-based test equipment where hermeticity is not mandated |
| 1N6109US/TR | Commercial-grade version; no MIL-PRF-19500 qualification or radiation testing | Restricted to industrial or commercial avionics development prototypes | Select only for early-stage design validation before transitioning to JANS-level parts for flight hardware |
Compared with JANS1N6109US/TR, JANTXV1N6109US offers identical electrical specs but lacks hermetic sealing and radiation tolerance, while 1N6109US/TR omits all military screening-making JANS1N6109US/TR the sole option for flight-certified, radiation-hardened Zener regulation.

FAQ
What is the Zener voltage tolerance specification for JANS1N6109US/TR?
The JANS1N6109US/TR has a Zener voltage tolerance of ±5% at 5 mA test current, meaning its nominal 15 V breakdown voltage falls within 14.25 V to 15.75 V across all qualified lots. This tolerance is verified per MIL-PRF-19500/537 screening and remains stable over temperature and lifetime. JANS1N6109US/TR maintains this spec under full Class K environmental stress testing.
Is JANS1N6109US/TR compatible with reflow soldering processes?
Yes, JANS1N6109US/TR is qualified for lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. Its hermetic TO-236AB package withstands thermal cycling without seal degradation. JANS1N6109US/TR must be stored per MIL-STD-750 Method 1081 to prevent moisture-induced popcorning during reflow.
Does JANS1N6109US/TR require derating above +70 °C?
Yes, JANS1N6109US/TR requires linear power derating above +70 °C: maximum dissipation decreases from 500 mW to zero at +175 °C. Derating follows MIL-PRF-19500/537 requirements and is defined in the official Microchip JANS1N6109US/TR datasheet. JANS1N6109US/TR performance remains within spec throughout this derated range.
What is the maximum leakage current specification for JANS1N6109US/TR?
The maximum leakage current for JANS1N6109US/TR is 100 nA at 12 V reverse bias and +25 °C, per MIL-PRF-19500/537 test condition 405. This value increases to ≤500 nA at +175 °C but remains within specification limits. JANS1N6109US/TR leakage is measured on every lot during qualification screening.
Can JANS1N6109US/TR be used in zero-bias detector applications?
No, JANS1N6109US/TR is not optimized for zero-bias RF detection; it is a precision Zener reference diode intended for regulated DC voltage generation. Its junction capacitance (~2 pF) and forward conduction characteristics are not characterized for detector linearity or sensitivity. JANS1N6109US/TR should only be used in reverse-biased Zener regulation roles per its qualified specification.
