2N5598

Overview

The General Semiconductor 2N5598 is a Junction Field-Effect Transistor (JFET) belonging to the standard N-channel depletion mode family. It utilizes a three-terminal TO-5 metal can package configuration, providing robust mechanical stability for high-reliability applications. The device operates as a voltage-controlled resistor or amplifier, characterized by its specific transconductance and breakdown voltage limits defined in official datasheets.

Feature Summary

• Utilizes a hermetically sealed TO-5 metal can package for environmental protection
• Operates as an N-channel depletion mode junction field-effect transistor
• Functions as a voltage-controlled element for signal amplification and switching

Applications

• Analog signal processing circuits
• Voltage-controlled resistance applications
• High-reliability military and aerospace electronic systems

Procurement Notes

Verify the manufacturer origin carefully, as General Semiconductor assets were acquired by onsemi. Ensure the component matches the original General Semiconductor specifications rather than modern equivalents unless cross-referenced. Confirm the package type is the legacy TO-5 metal can variant. Check for lead-free compliance if required by current assembly standards.

Selection Notes

Select this component when a discrete N-channel JFET with a hermetic metal package is required. It serves as a direct replacement for older designs utilizing the 2N5598 designation. Consider the physical size of the TO-5 package during PCB layout. Verify that the available supply chain supports legacy semiconductor sourcing requirements.

Part Context

This component represents a classic discrete semiconductor device from the General Semiconductor portfolio. It is part of a long-standing lineage of JFETs used in precision analog electronics. The brand heritage indicates a focus on high-reliability components often specified for defense and industrial sectors before corporate acquisitions consolidated the product lines.

Replacement Considerations

Direct replacements include the 2N5484 series or equivalent N-channel JFETs in TO-5 packages. Verify pinout compatibility and electrical parameters such as IDSS and VGS(off) against the original design requirements before substitution.
