J177_D74Z

Overview

The onsemi J177-D74Z is a P-channel Junction Field-Effect Transistor (JFET) designed for small-signal applications. It utilizes a TO-92 through-hole package with three pins. The device features a maximum power dissipation of 350mW and supports operating temperatures up to 150°C. Key electrical characteristics include a maximum drain-source on-resistance of 125 Ω and operation in depletion mode.

Feature Summary

• P-channel silicon junction FET technology
• Through-hole TO-92 package configuration
• Depletion mode operation capability

Applications

• Small signal amplification circuits
• Low noise pre-amplifier stages
• General purpose switching applications

Procurement Notes

Verify the specific suffix 'D74Z' against official onsemi documentation to confirm exact binning or tape-and-reel specifications, as generic part numbers may vary by manufacturer lot codes. Ensure the procurement source provides valid traceability data consistent with the component's industrial grade requirements.

Selection Notes

Select this component when a P-channel JFET with low input current and moderate on-resistance is required in a compact through-hole form factor. Consider the 125 Ω resistance limit and 350mW thermal constraints during circuit design to ensure reliable operation within the specified temperature range.

Part Context

This component belongs to the family of small-signal field-effect transistors manufactured by onsemi. Similar devices include the J176 series and other P-channel JFETs from legacy manufacturers like Fairchild and Texas Instruments, often sharing the TO-92 package style for general-purpose electronic designs.

Replacement Considerations

Potential substitutes include the J177/D28Z and J175D27Z, which share similar P-channel JFET characteristics and TO-92 packaging. Verify pinout compatibility and electrical parameters such as on-resistance and breakdown voltage before implementation.
