Device identity and key parametrics
The JFE150DCKR is a Texas Instruments N-Channel JFET in a 5-pin SC-70-5 (SOT-353) surface-mount package, rated for 40 V drain-to-source voltage and 50 mA maximum drain current. Its drain current at zero gate voltage (Idss) is 24 mA at Vds = 10 V, the figure that governs the device's on-resistance and drive capability in analog switch and low-noise amplifier front-ends. Input capacitance (Ciss) is 24 pF at Vds = 5 V, keeping the gate-drive burden low for high-frequency signal paths and fast switching applications.
The SC-70-5 package (also known as SOT-353) occupies a 2.1 mm × 2.0 mm footprint with a 0.65 mm lead pitch — a compact choice for dense mixed-signal boards where real estate is tight.
