| BF246B N-Channel Switch BF246B N-Channel Switch * This device is designed for low level analog switching, sample and hold circuits and chopper stabalized amplifiers. * Sourced from process 51. * See J111 for characteristics. TO-92 DGS 1. Drain 2. Gate 3. Source Absolute Maximum Ratings* Symbol VDG VGS IGF TJ, TSTG Notes: Ta = 25C unless otherwise noted Parameter Drain-Gate Voltage Gate-Source Voltage Forward Gate Current Operating and Storage Junction Temperature Range Value 25 -25 50 -55 ~ 150 Units V V mA C * These ratings are limiting values above which the serviceability of any semiconductor device may e impaired. 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.
