Overview
The MX2N4392 is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip 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 rating of 100 pA, and a maximum power dissipation of 360 mW. It operates within a temperature range from -65°C to +175°C.
Feature Summary
- Utilizes silicon technology for robust performance in demanding environments.
- Provides high thermal stability with operation up to +175°C.
- Features a single N-channel configuration for discrete circuit applications.
Applications
- High-frequency amplification circuits
- Low-noise signal processing stages
- Precision analog switching applications
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Microchip Technology before procurement. Confirm that the TO-18-3 package dimensions align with your PCB layout requirements. Ensure that the operating conditions remain within the specified voltage and temperature limits to maintain device reliability and prevent premature failure.
Selection Notes
Select this component when a ruggedized JFET with high-temperature capability is required. The TO-18-3 package offers superior thermal dissipation compared to plastic packages. Consider the 15 mA drain current specification for biasing requirements. Verify compatibility with existing circuit topologies requiring N-channel depletion mode operation.
Part Context
This part belongs to Microchip's discrete transistor portfolio, specifically within the JFET category. It serves as a specialized semiconductor device for analog electronics. The product line emphasizes reliability and performance in industrial and aerospace-grade applications where standard commercial components may not suffice.
Replacement Considerations
Consult official Microchip documentation for verified cross-reference part numbers. Do not substitute with generic equivalents without verifying pinout compatibility and electrical parameter tolerances. Ensure any replacement maintains the same package style and thermal characteristics.
