| 2N3819 2N3819 N-Channel RF Amplifier * This device is designed for RF amplifier and mixer applications operating up to 450MHz, and for analog switching requiring low capacitance. * Sourced from process 50. TO-92 1 1. Drain 2. Gate 3. Source Epitaxial Silicon Transistor Absolute Maximum Ratings* TC=25C unless otherwise noted Symbol VDG VGS ID IGF TSTG Parameter Drain-Gate Voltage Gate-Source Voltage Drain Current Forward Gate Current Storage Temperature Range Ratings 25 -25 50 10 -55 ~ 150 Units V V mA 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.
