PESD3V3U1UA,115

PESD3V3U1UA,115 is the tape-and-reel ordering code for the Nexperia PESD3V3U1UA unidirectional ESD protection diode in SOD-323, verified word-for-word on the maker’s chemical-content page with an RFS state. Verified figures: reverse standoff of 3.3 V maximum, breakdown between 4.5 V and 6.8 V at 5 mA (5.6 V typical), reverse leakage of 1 nA typical and 100 nA maximum, and diode capacitance of 2.6 pF typical and 3.1 pF maximum. The ultra-low capacitance is the selection point: this diode can sit on a 3.3 V high-speed line — USB, Ethernet and FireWire-class interfaces are the maker’s named applications — without loading the edge it protects. Selection advice: unidirectional protection suits a line with defined polarity; for a bipolar or AC-coupled 3.3 V line, choose a bidirectional device instead, and keep the ,115 packing suffix in the order string when the reel form is what your line consumes.
