Dual N-channel dual gate MOS-FET
BF1204
STATIC CHARACTERISTICS
Tj =25 °C; per MOS-FET; unless otherwise specied.
Note
1. RG1 connects gate 1 to VGG =5V.
DYNAMIC CHARACTERISTICS
Common source; Tamb =25 °C; VG2-S =4V; VDS =5V; ID = 12 mA; per MOS-FET (1); unless otherwise specied.
Notes
1. For the MOS-FET not in use: VG1-S = 0; VDS =0.
2. Measured in Fig.19 test circuit.
