2N4092UB

Overview

The Microchip Technology 2N4092UB is a single N-channel Junction Field-Effect Transistor (JFET) designed for through-hole mounting in the TO-18-3 metal can package. It operates with a drain-source breakdown voltage of 40 V and a gate-source breakdown voltage of -40 V. The device supports a continuous drain current of up to 100 pA and features a maximum power dissipation of 360 mW. It maintains an on-resistance of 50 Ohms and functions within an extended temperature range from -65°C to +175°C, ensuring reliability in demanding environments.

Feature Summary

• Utilizes silicon JFET technology for stable depletion mode operation
• Provides high thermal stability suitable for extreme temperature applications
• Features a hermetically sealed metal can package for robust protection

Applications

• High-reliability analog signal processing circuits
• Low-noise amplifier stages in aerospace systems
• Precision instrumentation requiring stable impedance characteristics

Procurement Notes

Verify the specific suffix 'UB' against the official Microchip datasheet to confirm pinout and electrical tolerances match your design requirements. Ensure the procurement channel provides traceable documentation for the TO-18-3 package. Confirm RoHS compliance status as indicated in the manufacturer's specifications before finalizing orders.

Selection Notes

Select this component when a ruggedized N-channel JFET with a 40 V rating is required for harsh environments. Compare the 50 Ohm on-resistance and 360 mW power dissipation limits against circuit load demands. Consider the TO-18-3 package constraints for PCB layout and thermal management solutions during the design phase.

Part Context

This part belongs to the 2N409x series of N-channel JFETs manufactured by Microchip Technology. It shares similar electrical characteristics with variants like the MX2N4092 but may differ in specific manufacturing lot qualifications or packaging details defined by the UB suffix. It serves as a discrete semiconductor solution for analog switching and amplification tasks.

Replacement Considerations

Cross-reference with MX2N4092 for potential functional equivalence in standard applications. Verify that alternative sources offer identical TO-18-3 pin configurations and meet the same -65°C to +175°C operating temperature range specifications.
