LSK189 SOT-23 3L ROHS

Overview

The LSK189 is a single N-channel JFET in a SOT-23 package. It features an ultra-low noise voltage of 1.8 nV/√Hz at 1 kHz and low input capacitance of 4 pF. The device has a gate-to-source breakdown voltage of -60 V, a typical drain-to-source saturation current (IDSS) of 5 mA, and a full conductance transconductance (Gfs) of 1500 µS. Operating temperatures range from -55°C to +150°C with continuous power dissipation of 300 mW.

Feature Summary

Ultra-low noise performance for sensitive signal applications
Low input capacitance suitable for high-frequency circuits
High transconductance for effective amplification
Wide operating temperature range

Applications

Audio preamplifiers
Instrumentation amplifiers
Low-noise oscillator circuits
Precision sensor interfaces

Procurement Notes

Verify the component matches the Linear Integrated Systems datasheet Doc 201150 Rev A20. Confirm the SOT-23 3L package and ROHS compliance status. Ensure the part number corresponds to the single N-channel JFET configuration. Check for any specific handling requirements related to electrostatic discharge protection during storage and installation.

Selection Notes

Select this component when minimizing input-referred noise voltage is critical. The low input capacitance makes it suitable for high-impedance sources. Verify that the required IDSS and Gfs ranges fit the circuit design constraints. Consider the thermal derating requirements if operating above 25°C ambient temperature.

Part Context

Linear Integrated Systems specializes in high-performance discrete semiconductors using proprietary processes. The LSK189 is part of their portfolio of low-noise JFETs, designed for applications requiring superior signal integrity. The company leverages expertise from previous semiconductor industry leaders to develop these components.

Replacement Considerations

For equivalent monolithic dual configurations, refer to the LSK489. Direct replacements should match the electrical characteristics, specifically the noise voltage, input capacitance, and pinout compatibility within the SOT-23 package.
