SST111 SOT-23 3L ROHS

Overview

The SST111 is a single N-channel JFET switch manufactured by Linear Integrated Systems in a SOT-23 package. It serves as a direct replacement for the Siliconix J/SST111 series. Key electrical characteristics include a gate-to-source cutoff voltage (VGS(off)) ranging from -3V to -10V, a drain-to-source on-resistance (rDS(on)) of 30Ω at VGS=0V, and a typical gate leakage current of 5pA. The device features fast switching with a turn-on time of 4ns and supports a continuous power dissipation of 350mW.

Feature Summary

Direct replacement compatibility with the Siliconix J/SST111 series
Ultra-low gate leakage current specification of 5pA
Fast switching capability with a 4ns turn-on time

Applications

Low noise signal switching circuits
High impedance buffer stages
Precision analog signal routing

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet indicates availability in both SOT-23 and TO-92 configurations. Confirm RoHS compliance status through official documentation or supplier declarations prior to procurement. Ensure the component source is authorized to guarantee authenticity and traceability.

Selection Notes

Select this component when low gate leakage and high input impedance are critical requirements. The 30Ω on-resistance makes it suitable for applications requiring minimal signal attenuation. Consider the -3V to -10V VGS(off) range to ensure proper biasing for the intended control logic levels.

Part Context

Linear Integrated Systems produces this discrete semiconductor using proprietary processes derived from expertise at Amelco, Union Carbide, Intersil, and Micro Power Systems. The company focuses on high-performance discrete devices, positioning this JFET within their portfolio of specialized analog switches.

Replacement Considerations

This part is documented as a direct replacement for the Siliconix J/SST111 series. Verify pinout compatibility between SOT-23 and legacy packages if substituting into existing designs.
