SOT-323
Description
The BAS69 series use 15V barrier, with extremely low junction capacitance, suitable for the detection of an RF signal and the compensation of the voltage drift with the temperature. The presented packages make the device ideal in applications where space saving is critical. The low junction capacitance will reduce the disturbance on the RF signal.
