TVS Diode Arrays (SPA®® Diodes)
Lightning Surge Protection- SP3312T Series
SP3312T Series 3.3V 15A Diode Array
RoHS
Pb GREEN
Description
The SP3312T integrates 4 channels (2 differential pair) of
low capacitance diodes to protect sensitive I/O pins against
lightning induced surge events and ESD. This robust device
can safely absorb up to 15A per IEC61000-4-5 (tp=8/20μs)
without performance degradation and a minimum
±30kV ESD per IEC61000-4-2 international standard. The
low loading capacitance makes the SP3312T ideal for
protecting high-speed signal pins.
