SST5484-E3

Overview

The Vishay Siliconix SST5484-E3 is a single N-channel Junction Field-Effect Transistor (JFET) manufactured using silicon technology. It is housed in a TO-92 through-hole package designed for general-purpose amplification and switching applications. The device features a gate-source breakdown voltage of -25 V and supports continuous drain currents up to 1 mA. Key electrical characteristics include a maximum reverse leakage current of 1 nA at VGS=0V and a typical forward transconductance of 1500 µmhos at VDS=5V and ID=1mA.

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout orientation and exact electrical tolerances, as variations may exist within the product family. Ensure the component meets RoHS compliance requirements for your target assembly process by checking the latest environmental declaration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing circuits requiring high input impedance and low noise figures in small form factors. The TO-92 package facilitates easy prototyping and through-hole mounting. Consider the -25 V gate-source limit when determining biasing networks. Evaluate thermal dissipation capabilities relative to the expected operating temperature range of -55°C to +150°C for robustness in varying environments.

Part Context

This JFET belongs to Vishay's discrete semiconductor lineup, specifically engineered for analog signal control. It serves as a fundamental building block for precision electronic designs where minimal signal distortion is critical. The device complements other passive and active components in power management and signal conditioning subsystems.

Replacement Considerations

Consult official Vishay substitution guides for verified equivalents. Generic replacements may differ in transconductance or leakage specifications. Verify pin compatibility and electrical ratings before integrating alternative sources into existing designs.
