**TVS Diode Array** (SPA[ ® ] Diodes) Lightning Surge Protection- SP3312T Series 

~~**RoHS Pb GREEN** L_IOL_]~~ 

## ~~SP3312T Series 3.3V 15A Diode Array~~ 

## ~~**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 component can safely absorb up to 15A per IEC 61000-4-5 (tp=8/20μs)without performance degradation and a minimum ±30kV ESD per IEC 61000-4-2 international standard. The low loading capacitance makes the SP3312T ideal for protecting high-speed signal pins.
