The -50V 2N4117/A, 2N4118/A, and 2N4119/A JFET’s are targeted for ultra high input impedance applications for mid to high frequency designs. Gate leakages are typically 1pA at room temperatures. The 2N4117 has a cutoff voltage of less than 1.8V ideal for lowlevel power supplies. The TO-72 package is.
