Overview
The Microchip Technology 2N4092 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. Key electrical characteristics include a zero-gate-voltage drain current of 15 mA, a continuous drain current of -100 pA, and a drain-source on-resistance of 50 Ohms. The component supports a power dissipation of 360 mW and operates within a temperature range from -65 C to +175 C.
Feature Summary
- Utilizes silicon JFET technology for reliable signal processing.
- Provides high thermal stability with an extended operating temperature range up to +175 C.
- Features a robust metal can package suitable for harsh environments.
Applications
- Low-noise analog signal amplification circuits
- High-impedance input stages in measurement equipment
- Precision current source applications
Procurement Notes
Verify the specific manufacturer origin, as the 2N4092 designation is historically associated with multiple vendors including Central Semiconductor and Intersil. Confirm that the Microchip Technology variant meets all required electrical tolerances and packaging specifications for your design. Ensure compliance with RoHS directives if applicable, noting that some legacy variants may not be compliant.
Selection Notes
Select this component when a single N-channel JFET with a 40 V breakdown voltage and 15 mA IDSS is required. Consider the TO-18-3 package constraints for board layout. Compare against MV2N4091 or MX2N4092 if different IDSS values or pinout configurations are needed for the specific circuit topology.
Part Context
The 2N4092 belongs to the standard military-grade JFET family. Microchip Technology produces this component alongside related variants like the MV2N4091 and MX2N4092, which share similar voltage ratings but differ in current specifications. These devices are part of a broader portfolio of discrete transistors used in industrial and aerospace electronics.
Replacement Considerations
Public confirmed substitute part numbers: MV2N4091, MX2N4092, 2N4092 (Central Semiconductor). Verify pinout compatibility and electrical parameter overlaps before substitution.
