Product Information

J108 / J109 / J110 Discrete POWER & Signal Technologies J108 J109 J110 G SD TO-92 N-Channel Switch This device is designed for analog or digital switching applications where very low on resistance is mandatory. Sourced from Process 58. Absolute Maximum Ratings* Symbol VDG VGS IGF TJ, Tstg Drain-Gate Voltage Gate-Source Voltage Forward Gate Current TA = 25°C unless otherwise noted Parameter Value 25 - 25 10 -55 to +150 Units V V mA °C Operating and Storage Junction Temperature Range *These ratings are limiting values above which the serviceability of any semiconductor device may be impaired. NOTES: 1) These ratings are based on a maximum junction temperature of 150 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
