2N5486 APM PBFREE

Overview

The Central Semiconductor Corp 2N5486 APM PBFREE is an N-channel Junction Field-Effect Transistor (JFET) designed for general-purpose amplification and switching applications. It features a maximum drain-source voltage of 25 V and a gate-source voltage rating of 25 V. The device supports a continuous drain current of 100 mA with a typical on-resistance of 300 Ohms at zero gate bias. Key electrical characteristics include a minimum forward transconductance of 1000 µmhos and a maximum gate reverse current of 1 nA. The component operates within a temperature range of -65°C to +150°C and is housed in a TO-92-3 package.

Feature Summary

• Provides high input impedance suitable for low-noise signal processing circuits
• Capable of operation across extended industrial temperature ranges
• Designed for linear amplification and analog switching functions

Applications

• Low-noise audio preamplifiers
• High-impedance buffer stages
• Analog signal switching matrices

Procurement Notes

Verify the specific suffix 'APM' against the manufacturer's official datasheet to confirm packaging type and binning specifications. Ensure that the 'PBFREE' designation aligns with current environmental compliance requirements for the target assembly process. Cross-reference the Mouser or DigiKey part numbers with the original equipment manufacturer's documentation to validate authenticity and lot traceability before procurement.

Selection Notes

Select this component when a standard N-channel JFET with moderate current handling and low noise performance is required. Compare the 100 mA drain current limit and 300 Ohm on-resistance against circuit load requirements. Verify that the TO-92-3 through-hole package fits the available board space and thermal management constraints relative to alternative surface-mount options.

Part Context

This part belongs to the Central Semiconductor JFET family, specifically utilizing silicon planar technology. It serves as a discrete replacement for legacy junction field-effect transistors in analog design architectures. The component is distinct from bipolar transistors and MOSFETs due to its depletion-mode operation and inherent high input impedance characteristics.

Replacement Considerations

Consult official substitution guides for equivalent N-channel JFETs such as the 2N5485 or 2N5487 if pin compatibility and voltage ratings match. Verify that alternative devices meet the same 100 mA current and 25 V voltage specifications without compromising the required transconductance levels.
