Low diode capacitance
Designed for RF applications
Low profile packages
Very low parasitic inductor and resistor
BAS69KFILM
(Single)
SOD-523
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.
