Linear Systems JFETs LSK170D TO-92 3L ROHS

The LSK170D is a single N-channel JFET designed for low-noise, high-input-impedance applications in audio, instrumentation, and sensor circuits. It is available in a through-hole TO-92 3L package with a maximum power dissipation of 400 mW at 25°C. The device features a gate-to-source breakdown voltage of 40 V minimum, a typical transconductance of 22 mS, and an input noise voltage of 0.9 nV/√Hz at 1 kHz. The LSK170D has a drain-to-source saturation current range of 18.0 to 30.0 mA at VDS = 10 V and VGS = 0 V. It is RoHS compliant and offers a high input impedance of 20 GΩ typical and an input capacitance of 20 pF maximum. The part is a pin-for-pin replacement for the Toshiba 2SK170, suitable for battery-operated portable devices requiring minimal noise and compact form factors.
