MX2N4858UB/TR

Overview

The MX2N4858UB/TR is a silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip Technology. It features a surface-mount SMD-3 package and operates within a temperature range of -65°C to +200°C. Key electrical specifications include a drain-source breakdown voltage of 30 V, a gate-source breakdown voltage of -30 V, and a continuous drain current of 175 mA. The device exhibits a maximum power dissipation of 1.8 W and an on-resistance of 25 Ohms.

Feature Summary

Utilizes silicon technology for robust performance in high-reliability applications.
Supports surface-mount installation via an SMD-3 package configuration.
Capable of operating at elevated temperatures up to 200°C.

Applications

High-reliability analog signal processing circuits
Military and aerospace electronic systems
Precision low-noise amplifier stages

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and qualification level. Ensure compatibility with existing PCB footprints for the SMD-3 configuration. Confirm that the component meets all required environmental and military standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when a surface-mount JFET with high-temperature capability is required. Compare the 30 V breakdown voltage and 1.8 W power dissipation against circuit requirements. Consider the SMD-3 footprint constraints and verify that the 175 mA current rating aligns with the design's operational limits.

Part Context

This part belongs to the Microchip high-reliability JFET portfolio, often associated with MIL-PRF-19500 qualifications. It serves as a surface-mount alternative to through-hole variants like the MX2N4858UB, maintaining similar electrical characteristics while adapting to modern assembly processes.
