Description
LSJ111 N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J111
This n-channel JFET is optimised for low noise high performance switching. The part is particularly suitable for use in low noise audio amplifiers. The SOT-23 package is well suited for cost sensitive applications and mass production. (See Packaging Information). FEATURES DIRECT REPLACEMENT FOR SILICONIX J111 LOW GATE LEAKAGE CURRENT 5pA FAST SWITCHING t(on) ≤ 4ns ABSOLUTE MAXIMUM RATINGS @ 25°C (unless otherwise noted)
Maximum Temperatures Storage Temperature ‐55°C to +150°C LSJ111 Benefits: Operating Junction Temperature ‐55°C to +135°C Short Sample & Hold Aperture Time Maximum Power Dissipation Low insertion loss Continuous Power Dissipation 350mW Low Noise MAXIMUM CURRENT LSJ111 Applications: Gate Current (Note 1) 50mA Analog Switches MAXIMUM VOLTAGES Commutators Gate to Drain Voltage VGDS = ‐35V Choppers Gate to Source Voltage VGSS = ‐35V LSJ111 ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTIC MIN TYP.
