2N5458_D27Z

Overview

The onsemi 2N5458_D27Z is an N-channel silicon small-signal Junction Field-Effect Transistor (JFET) housed in a TO-92 through-hole package. It operates with a maximum drain-source voltage of 25 V and a gate-source voltage limit of 25 V. The device dissipates up to 310 mW of power and supports a junction temperature of 135°C. Key electrical characteristics include a typical drain current of 2 mA at 15 V, a maximum input capacitance of 7 pF at 15 V, and a gate cutoff voltage of 1 V at 10 nA.

Feature Summary

• Utilizes depletion mode operation for standard JFET functionality
• Designed for low-noise signal processing applications
• Features high input impedance suitable for buffer circuits

Applications

• Low-noise preamplifier stages
• High-impedance buffer circuits
• Analog switch implementations

Procurement Notes

Verify the specific manufacturer designation for the suffix D27Z, as official documentation primarily lists the base part number 2N5458G from onsemi. Confirm component availability status, as related variants may be marked as obsolete or end-of-life. Ensure the procurement source provides valid RoHS compliance data and authentic datasheets matching the specified package type.

Selection Notes

Select this component when a robust N-channel JFET with a 25 V breakdown rating is required for discrete analog designs. Compare against surface-mount alternatives like the MMBF5458 if board space constraints exist. Verify that the TO-92 package dimensions align with the target PCB footprint and thermal management requirements.

Part Context

This component belongs to the standard 2N5458 family of N-channel JFETs. Variants such as the 2N5457 differ primarily in pinout configuration or specific gain groupings. The D27Z suffix typically indicates a specific tape-and-reel or bulk packaging format rather than a change in electrical performance parameters.

Replacement Considerations

Direct substitutes include the Central Semiconductor 2N5458 and Fairchild 2N5457D27Z. Surface-mount equivalents are available as the MMBF5458. Verify pinout compatibility before substitution.
