AN301 High-Speed DMOS FET Analog Switches and Switch Arrays

AN301 High-Speed DMOS FET Analog Switches and Switch Arrays

The Siliconix SD210 and SD5000 series are discretes and quad monolithic arrays, respectively, of single-pole single-throw analog switches. These switches are n-channel enhancement-mode silicon field effect transistors built using double-diffusion MOS (DMOS) silicon gate technology. Surface-mount ver.

Features

s, DMOS can handle wideband signals with high off-isolation and minimum crosstalk. The SD210 series of single-channel FETs is available without Zener protection to reduce leakage and in Zener protected versions to reduce electrostatic discharge hazards. The SD5000 series is available in 16-lead dual in-line plastic or sidebraze ceramic packages. Analog signal voltage ranges up to 10 V and frequencies up to 1 GHz can be controlled. For surface-mount applications the SST211 series is offered in the TO-253 (SOT-143) package. The SD5400 series comes in the narrow body gull-wing SO-14 package. Appl.
