2N4093

Jfets Overview

The Microchip Technology 2N4093 is a single N-channel Junction Field-Effect Transistor (JFET) manufactured using silicon technology. It is housed in a TO-18-3 metal can package designed for through-hole mounting. The device features a drain-source breakdown voltage of 40 V and a gate-source breakdown voltage of -40 V. At zero gate-source voltage, the drain current is specified at 8 mA, with a maximum on-resistance of 80 Ohms. The component supports a power dissipation of 360 mW and operates within an extended temperature range from -65°C to +175°C.

Jfets Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct binning and electrical tolerances. Confirm RoHS compliance status as indicated in the manufacturer documentation, noting that standard versions may not meet current environmental directives. Validate the package type and pinout configuration prior to integration into the PCB layout to prevent assembly errors.

Jfets Selection Notes

Select this component when a low noise figure and high input impedance are required for analog signal paths. Compare the 8 mA drain current specification against circuit requirements to ensure proper biasing. Consider the TO-18-3 package constraints for board space and thermal management capabilities relative to alternative surface-mount options.

Jfets Part Context

The 2N4093 belongs to the 2N409x series of N-channel JFETs produced by Microchip Technology. This family includes variants such as the 2N4091 and 2N4092, which share similar voltage ratings but differ in their zero-bias drain current specifications. These components are typically utilized in specialized analog electronics requiring reliable performance under varying thermal conditions.

Jfets Replacement Considerations

Direct substitutes include the MX2N4093 and MV2N4093, which maintain identical electrical characteristics and pin configurations. Verify compatibility with existing circuit biasing networks before swapping between these specific part numbers.
