2SK242-5-TB-E

Overview

The 2SK242-5-TB-E is an N-channel JFET manufactured by onsemi, designed for high-frequency low-noise amplifier applications. It operates with a drain-source voltage of 25 V and a continuous drain current of 50 mA. The device features a maximum power dissipation of 400 mW and functions within a temperature range of -55°C to +150°C. Packaged in the SC-70 (SOT-323) surface-mount format, it offers low input capacitance and high reliability for signal processing tasks.

Feature Summary

Optimized for high-frequency low-noise amplifier circuits
Capable of operation at elevated temperatures up to 150°C
Utilizes a compact surface-mount package for space-constrained designs

Applications

High-frequency low-noise amplification stages
RF signal processing circuits
Precision analog front-end modules

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm RoHS compliance status and specific tape-and-reel packaging requirements prior to procurement. Ensure supply chain stability as discrete semiconductor components may experience lifecycle variations or obsolescence notices from the manufacturer.

Selection Notes

Select this component when low noise figure and high-frequency performance are critical requirements. The SC-70 package suits automated surface-mount assembly processes. Evaluate thermal management needs given the 400 mW dissipation limit and ensure gate-source voltage ratings align with circuit biasing conditions to prevent breakdown during operation.

Part Context

This part belongs to onsemi's portfolio of discrete JFETs intended for analog and RF applications. The 2SK series designation indicates compatibility with legacy specifications while meeting modern manufacturing standards. It serves as a specialized solution for maintaining signal integrity in sensitive electronic systems requiring minimal noise introduction.

Replacement Considerations

Cross-reference with other N-channel JFETs offering similar 25 V ratings and 50 mA current capabilities. Verify pinout compatibility and package dimensions before substitution. Consider alternatives like the CPH3910-TL-E if parameter matching is required, though functional equivalence must be validated against specific circuit requirements.
