MX2N4858UB

Overview

The MX2N4858UB is a Silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip Technology. It utilizes a TO-18-3 metal can package designed for through-hole mounting. The device operates within a temperature range of -65°C to +200°C and features a single configuration. Key electrical characteristics include a drain-source breakdown voltage of 40V, a gate-source breakdown voltage of -30V, and a maximum power dissipation of 360mW.

Feature Summary

High-temperature operation capability up to 200°C
Robust silicon construction in a hermetically sealed metal can
Designed for high-voltage analog switching applications

Applications

High-temperature analog signal switching
Precision current source circuits
Low-noise amplifier input stages

Procurement Notes

Verify the specific suffix 'UB' against the official Microchip datasheet to confirm pinout and electrical tolerances. Ensure the procurement channel provides traceability documentation required for military or aerospace specifications associated with this component series.

Selection Notes

Select this component when a hermetically sealed JFET is required for extreme thermal environments exceeding standard plastic package limits. Consider the TO-18-3 form factor for compatibility with existing through-hole layouts requiring high reliability.

Part Context

This part belongs to the 2N4858 family of N-channel JFETs produced by Microchip Technology. These devices are characterized by their use in ruggedized electronics where standard commercial components fail due to thermal stress. The 'MX' prefix typically denotes a specific manufacturing lot or enhanced specification variant within the broader 2N4858 product line.
