SMMBFJ310LT3G

Overview

The SMMBFJ310LT3G is a single N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It utilizes silicon technology and is housed in an SOT-23-3 surface-mount package. The device features a drain-source breakdown voltage of 25 V and a gate-source breakdown voltage of 25 V. At zero gate-to-source voltage, the drain current ranges from 24 mA to 60 mA. This component belongs to the MMBFJ310L series and is designed for applications requiring small-signal amplification or switching within these electrical limits.

Feature Summary

• Single N-channel JFET configuration
• Silicon-based semiconductor technology
• SOT-23-3 surface-mount packaging

Applications

• Small-signal amplification circuits
• Low-noise analog signal processing
• High-impedance input stages

Procurement Notes

Verify the complete part number including the suffix LT3G against official onsemi documentation to ensure correct packaging and compliance specifications. Confirm that the SOT-23-3 package type matches the design requirements. Check RoHS status details through authorized channels. Ensure the supplier provides valid traceability for the MMBFJ310L series component.

Selection Notes

Select this component when a single N-channel JFET with a 25 V breakdown rating is required. The 24 mA to 60 mA drain current range at Vgs=0 must align with circuit biasing needs. The SOT-23-3 package dictates the physical footprint constraints. Verify thermal dissipation capabilities relative to the specific application environment.

Part Context

This part is a member of the MMBFJ310L series from onsemi. It shares the core electrical characteristics of the standard MMBFJ310 but includes specific manufacturing and packaging identifiers in its designation. The LT3G suffix indicates the tape-and-reel packaging format and lead-free compliance status defined by the manufacturer.

Replacement Considerations

Direct substitutes include other MMBFJ310 variants from different manufacturers that match the SOT-23-3 package and 25V/24-60mA specifications. Verify pinout compatibility and parameter tolerances before substitution.
