Central Semiconductor Corp. JFETs CMPF4391 TR TIN/LEAD

The CMPF4391 is a silicon N-channel JFET for switching applications, housed in an SOT-23 surface mount package with dimensions of 2.80 to 3.05 mm in length and 1.19 to 1.40 mm in width. It has a drain-gate, gate-source, and drain-source voltage rating of 40 V, a maximum power dissipation of 350 mW, and an operating junction temperature range of -65°C to +150°C. The device has a thermal resistance of 357 °C/W and a gate-source cutoff voltage of 4.0 to 10 V. The part is available in tape and reel packaging with a TR suffix and uses tin/lead plating as indicated by the TIN/LEAD suffix.
