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 ele-
ments 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.
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 protec-
tion, high-speed switching, and voltage clamping.
