U1898

U1898 U1898 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 1 1. Drain 2. Source 3. Gate Absolute Maximum Ratings* Ta=25°C unless otherwise noted Symbol VDG VGS IGF TJ, TSTG Parameter Drain-Gate Voltage Gate-Source Voltage Forward Gate Current Operating and Storage Junction Temperature Range Ratings 40 -40 50 -55 ~ 150 Units V V mA °C * This ratings are limiting values above which the serviceability of any semiconductor device may be impaired. NOTES: 1) These rating are based on a maximum junction temperature of 150 degrees C. 2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
