Description
The HBAT-5400 series of Schottky
diodes, commonly referred to as
clipping /clamping diodes, are
optimal for circuit and waveshape
preservation applications with
high speed switching. Low series
resistance, R
S
, makes them ideal
for protecting sensitive circuit
elements against high current
transients carried on data lines.
With picosecond switching, the
HBAT-540x 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, high-
speed switching, and voltage
clamping.
