Overview
The MV2N4393 is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip Technology. It utilizes silicon technology and is housed in a TO-18-3 through-hole package. Key electrical specifications include a drain-source breakdown voltage of 40 V, a gate-source breakdown voltage of -40 V, and a maximum power dissipation of 360 mW. The device operates within a temperature range of -65°C to +175°C.
Feature Summary
- Provides single N-channel JFET configuration for signal processing applications.
- Capable of operation across an extended industrial temperature range up to 175°C.
- Features high input impedance characteristics inherent to JFET technology.
Applications
- Low-noise amplifier circuits
- High-impedance switching applications
- Analog signal conditioning
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm exact binning or testing criteria. Confirm RoHS compliance status as indicated in the datasheet, noting that some variants may not meet current environmental directives. Ensure the TO-18-3 package type matches the target PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring robust performance at elevated temperatures up to 175°C. The 40 V breakdown voltage rating suits moderate voltage applications. Consider the TO-18-3 package constraints for board space. Verify that the required drain current and transconductance parameters align with the specific operational needs of the analog circuit design.
Part Context
This part belongs to the Microchip JFET family, which includes various N-channel and P-channel devices. These components are typically used in precision analog electronics where low noise and high input impedance are critical. The MV2N4393 shares functional similarities with other standard JFETs but offers specific thermal and electrical ratings defined by the manufacturer.
Replacement Considerations
Consult official substitution guides for compatible equivalents. Generic replacements must match the N-channel configuration, TO-18-3 package, and minimum 40 V breakdown voltage ratings to ensure circuit compatibility.
