BAS40 8700 E.
Thomas Road Scottsdale, AZ 85251 Tel: (480) 941-6300 Fax: (480) 947-1503 and BAS70 SCHOTTKYarray™ SERIES DESCRIPTION Various configurations of Schottky barrier's diodes in SOT-23 packages are provided for general-purpose use in high-speed switching, mixers and detector applications.
They may also be used for signal terminations at the board level.
This helps maintain signal integrity and counteract the transmission-line effects with (PC) board traces by clamping over/and undershoot from signal reflections with the schottky-low-threshold voltages.
This type of termination also does not depend on matching the transmission line characteristic impedance, making it particularly useful where line impedance is unknown or a variable.
This method of termination can control distortions of clock, data, address, and control lines as well as provides a stabilizing effect on signal jitter.
It can also significantly reduce power consumption compared to standard resistor- based termination methods.
