SINGLE 3 SERIES 3
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 capacitance minimizes waveshape loss that causes signal degradation.
Applications
RF and computer designs that require circuit protection, highspeed switching, and voltage clamping.
