Description
The SD210DE/214DE are enhancement-mode MOSFETs
designed for high speed low-glitch switching in audio, video,
and high-frequency applications. The SD214DE is normally used
for
±10-V analog switching. These MOSFETs utilize lateral
construction to achieve low capacitance and ultra-fast switching
speeds. These MOSFETs do not have a gate protection Zener
diode which results in lower gate leakage and
±
voltage capability
from gate to substrate. A poly-silicon gate is featured for
manufacturing reliability.
For similar products see: quad array—SD5000/5400 series, and
Zener protected—SD211DE/SST211 series.
