2SK3666-2-TB-E

Overview

The onsemi 2SK3666-2-TB-E is an N-channel Junction Field Effect Transistor (JFET) designed for low-frequency general-purpose amplifier and impedance converter applications. It operates with a drain-source voltage of 50 V and a maximum continuous drain current of 10 mA. The device features a typical zero-gate-voltage drain current of 4 mA and a gate-source cutoff voltage ranging from -0.5 V to -4 V at 1 µA. Packaged in a compact SOT-23 form factor, it dissipates up to 350 mW of power and supports junction temperatures up to 150°C.

Feature Summary

N-channel JFET technology optimized for linear amplification
Suitable for high-input-impedance buffering stages
Compact surface-mount packaging for space-constrained designs

Applications

Low-frequency general-purpose amplifiers
Impedance converter circuits
High-impedance input buffers

Procurement Notes

Verify the manufacturer source document to confirm electrical parameters match design requirements. Ensure the SOT-23 package dimensions align with PCB layout constraints. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check for any specific handling instructions regarding electrostatic discharge during installation.

Selection Notes

Select this component when a small-signal N-channel JFET is required for low-noise, low-frequency analog signal processing. Compare Idss and Vgs(off) tolerances against circuit biasing needs. Consider the thermal dissipation limits relative to the expected operating current. Verify that the 50 V breakdown voltage provides sufficient margin for the application's supply rails.

Part Context

This part belongs to the 2SK3666 family of N-channel JFETs produced by onsemi. It shares functional similarities with other low-frequency JFETs but is distinguished by its specific pinout and packaging in the SOT-23 format. The suffix indicates the specific tape-and-reel packaging configuration used for automated assembly processes.

Replacement Considerations

Direct substitutes may include other N-channel JFETs in SOT-23 packages with comparable Vdss and Idss ratings. Verify pin compatibility before replacement. Generic equivalents might require circuit adjustments due to variations in transconductance or cutoff voltage ranges.
