Description
The HSMS-2700 series of Schottky diodes, commonly
referred to as clipping/clamping diodes, are optimal for
circuit and waveshape preservation applications with
high speed switching. Ultra-low series resistance, R
S
,
makes them ideal for protecting sensitive circuit elements
against higher current transients carried on data lines.
With picosecond switching, the HSMS-270x can respond
to noise spikes with rise times as fast as 1 ns. Low ca-
pacitance minimizes waveshape loss that causes signal
degradation.
