LSK170A TO-92 3L ROHS

Overview

The LSK170A TO-92 3L ROHS is a single N-channel JFET designed for ultra-low noise and high input impedance applications. It features a minimum gate-to-source breakdown voltage of -40V, a typical transconductance of 22mS at 1kHz, and an input capacitance of 20pF maximum. The device offers a narrow IDSS range of 2.6mA to 6.5mA and operates within a junction temperature range of -55°C to +135°C with continuous power dissipation of 400mW.

Feature Summary

Ultra-low noise performance optimized for both high and low frequencies
High input impedance with exceptionally low leakage current
Narrow IDSS grading range to facilitate design stability
Direct pin-for-pin replacement for Toshiba 2SK170

Applications

Audio amplifiers and preamplifiers
Discrete low-noise operational amplifiers
Guitar pickups and effects pedals
Microphones and audio mixer consoles
Acoustic sensors and hydrophones

Procurement Notes

Verify the specific grade suffix (A, B, C, or D) matches the required IDSS range for your circuit design. Confirm RoHS compliance status if non-standard parts are requested. Ensure the package type corresponds exactly to the PCB footprint requirements. Check datasheet notes regarding voltage specification testing methods before finalizing procurement specifications.

Selection Notes

Select the LSK170A variant for lower saturation drain currents ranging from 2.6mA to 6.5mA. Consider higher grades (B, C, D) only if the application requires increased current handling capabilities beyond the A-grade limits. Evaluate the trade-off between noise voltage and capacitance based on the specific frequency response needs of the target circuit.

Part Context

This component belongs to the LSK170 series of high input impedance, ultra-low noise JFETs manufactured by Linear Integrated Systems. The series includes variants in SOT-23, TO-92, and SOT-89 packages. It serves as an improved functional replacement for Interfet models IF1320, IF1330, IF1331, and IF4500.
