Surge and ESD Protection for
Safeguarding Gigabit Ethernet
Gigabit Ethernet transceivers, built on advanced semiconductor process nodes, are more
sensitive to electrical transient events than ever before. Today’s advanced PHYs require
state of the art TVS protection arrays that can absorb the expected transient energy, clamp
the incoming surge to a safe level, and present sufficiently low junction capacitance to be
electrically transparent to the system under normal operation.
• AEC-Q100 qualified
• Small 3-pin 0402 package
(1.0 x 0.60 x 0.40mm)
RClamp® 2502L
