Overview
The MQ2N4860 is a silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip Technology. It features a single configuration housed in an SMD-3 surface-mount package. The device supports a drain-source breakdown voltage of 30 V and a gate-source breakdown voltage of -30 V. It operates with a continuous drain current of 175 mA and exhibits a maximum on-resistance of 25 Ohms at zero gate-source voltage. The component handles a power dissipation of 1.8 W and functions within a temperature range of -65°C to +200°C.
Feature Summary
- Utilizes silicon technology for robust performance in high-temperature environments up to 200°C.
- Designed as a single N-channel JFET suitable for surface-mount assembly applications.
- Provides stable operation with defined breakdown voltages for both drain-source and gate-source terminals.
Applications
- High-temperature analog signal processing circuits
- Low-noise amplifier stages requiring surface-mount integration
- Precision current source implementations
Procurement Notes
Verify the specific suffix and package type against official Microchip documentation before procurement, as variations exist within the family. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the ordering part number matches the required surface-mount configuration and electrical specifications precisely to avoid integration errors.
Selection Notes
Select this component when a surface-mount N-channel JFET with high thermal tolerance is required. Compare the 175 mA drain current and 25 Ohm on-resistance against circuit requirements. Consider the SMD-3 package constraints for PCB layout. Verify that the 30 V breakdown ratings align with the system's maximum operating voltages to ensure reliability under stress conditions.
Part Context
This device belongs to the Microchip JFET product line, specifically designed for applications demanding high reliability and wide temperature operation. It complements through-hole variants like the MV2N4860 by offering a compact surface-mount solution. The series is characterized by consistent silicon fabrication standards and strict parameter control for analog switching and amplification tasks.
Replacement Considerations
Cross-reference with other Microchip SMD JFETs such as the MQ2N4861UB or MQ2N4859UB/TR if pinout compatibility and similar electrical characteristics are required. Verify that substitute parts maintain the same SMD-3 package footprint and meet the 30 V breakdown voltage requirement.
