HBAT-5400, 5402, 540B, 540C
High Performance Schottky Diode
for Transient Suppression
Data Sheet
Description
The HBAT-540x 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 capaci-
tance minimizes waveshape loss that causes signal deg-
radation.
Features
•
Ultra-low Series Resistance for Higher Current
Handling
•
Low Capacitance
•
Low Series Resistance
•
Lead-free Option Available
Applications
RF and computer designs that require circuit protection,
high-speed switching, and voltage clamping.
