Jfets datasheet and documents for SST4119 SOT-23 3L ROHS

SST4119 SOT-23 3L ROHS

Jfets Overview

The SST4119 is an ultra-high input impedance N-channel JFET amplifier housed in a SOT-23 package. It features a gate-source breakdown voltage of -40V and a saturation drain current range of 0.20 to 0.80 mA at VDS=10V. The device exhibits a common-source forward transconductance between 100 and 700 µS, with a maximum gate reverse current of 10 pA at 25°C. Total device dissipation is rated at 300mW, derating by 2mW/ºC above 25ºC.

Jfets Feature Summary

Ultra-high input impedance for minimal circuit loading
Low power consumption characteristics
Symmetrical geometry allowing interchangeable source and drain leads

Jfets Applications

High-impedance signal amplification
Precision analog circuits requiring low leakage
Battery-powered instrumentation

Jfets Procurement Notes

Verify the specific suffix matches the required electrical tolerance class. Confirm the package type corresponds to the SOT-23 footprint. Ensure RoHS compliance documentation aligns with project requirements. Cross-reference the datasheet revision date against manufacturing batches for consistency.

Jfets Selection Notes

Select based on required transconductance and leakage specifications. Compare IDSS ranges against circuit biasing needs. Consider thermal derating limits for high-temperature environments. Evaluate package compatibility with existing PCB layouts.

Jfets Part Context

Part of the Linear Integrated Systems 4117/4118/4119 series of N-channel JFETs. Designed for applications demanding superior input impedance and low noise performance. Manufactured using proprietary processes developed from historical expertise in discrete semiconductor technology.

Jfets Replacement Considerations

Direct replacements include SST4117 and SST4118 within the same series. Verify pinout compatibility as source and drain are interchangeable due to symmetrical geometry. Check if alternative packages like TO-72 or TO-92 fit the mechanical constraints.
