| High Speed DMOS N-Channel Switch CORPORATION SD403 FEATURES DESCRIPTION The Calogic SD403 is an N-Channel Enhancement-Mode Lateral DMOS FET. This product has very low capacitance, (crss < 0.4pf typical) allowing for high speed switching (tr 1ns). The SD403 is a high gain device (19mmhos) and has good performance values for sample and hold circuits, video switches and switch drivers where lower capacitance and high speed switching are critical.
