2N5658

Overview

The 2N5658 is a silicon junction field-effect transistor (JFET) manufactured by Microchip Technology. It is designed for general-purpose amplification and switching applications in through-hole configurations. The device operates with a maximum drain-source voltage of 40V and can handle a continuous drain current of up to 50mA. Power dissipation capabilities are rated at 360mW, ensuring reliable performance within specified thermal limits. This component utilizes standard N-channel JFET technology suitable for analog signal processing tasks.

Feature Summary

• Utilizes silicon-based JFET technology for stable analog operation
• Supports through-hole mounting for robust mechanical integration
• Provides high input impedance characteristics typical of JFET structures

Applications

• General-purpose analog signal amplification circuits
• Electronic switching applications requiring low gate drive current
• Input stages for audio or sensor interfacing equipment

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with project timelines. Confirm that the received components match the 2N5658 designation exactly, as suffixes may indicate different packaging or testing standards. Check for physical damage to leads before soldering. Ensure storage conditions prevent moisture absorption if long-term storage is required prior to assembly.

Selection Notes

Select this component when a through-hole N-channel JFET with 40V breakdown voltage is required. Consider its 50mA current rating against circuit load requirements. Evaluate thermal management needs given the 360mW power dissipation limit. Compare input impedance specifications against other available JFETs if signal integrity is critical. Ensure the package style matches the existing PCB footprint constraints.

Part Context

This part belongs to Microchip's discrete semiconductor portfolio, specifically within the transistor category. It serves as a fundamental active component for linear and switching circuits. The 2N5658 represents a standard military-grade or commercial-grade JFET option depending on the specific ordering suffix, providing designers with a reliable solution for legacy and new analog designs requiring through-hole implementation.

Replacement Considerations

Consult official cross-reference guides for direct replacements. Verify pinout compatibility and electrical parameters such as Vgs(off) and Idss before substituting. Ensure any alternative component meets the same voltage and current ratings.
