Overview
The PN4393_D26Z is a small signal N-channel silicon Junction Field-Effect Transistor (JFET) manufactured by onsemi. It is housed in a TO-92 through-hole package with kinked leads. The device operates in depletion mode and features a maximum drain-source on-resistance of 100 ohms. Key electrical characteristics include a maximum feedback capacitance (Crss) of 3.5 pF. The component is lead-free and RoHS compliant, designed for general-purpose switching and amplification applications within standard operating temperature ranges.
Feature Summary
- N-channel JFET technology for signal processing
- Depletion mode operation capability
- Low feedback capacitance for high-frequency performance
Applications
- Small signal amplification circuits
- Analog switching applications
- General-purpose discrete transistor designs
Procurement Notes
Verify the specific suffix D26Z against official manufacturer documentation to confirm exact packaging or tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TO-92-3 kinked lead configuration. Confirm that the depletion mode characteristic aligns with the circuit design requirements before integration.
Selection Notes
Select this component when an N-channel JFET with low input capacitance is required for analog signal paths. The TO-92 package suits through-hole assembly processes. Verify that the 100 ohm on-resistance meets the impedance constraints of the target application. Consider the depletion mode nature for normally-on circuit topologies.
Part Context
This part belongs to the broader category of small signal field-effect transistors produced by onsemi. It serves as a discrete semiconductor solution for linear and switching applications. The PN4393 variant specifically utilizes silicon junction FET technology, distinguishing it from MOSFET or bipolar transistor alternatives within the same product portfolio.
Replacement Considerations
Consult official cross-reference guides for equivalent N-channel JFETs in TO-92 packages. Verify pinout compatibility and electrical parameter overlaps such as Crss and Rds(on). No direct substitute part numbers are confirmed in the provided data.
