The Nexperia PESD3V3Z1BSFYL is a single-channel bidirectional ESD suppressor diode in an 0201 case, the imperial equivalent of the DFN0603 metric outline. It has a 3.3V reverse standoff voltage with a 6.9V breakdown and absorbs 9.5A of peak pulse current. The distinguishing figure is its 280fF capacitance, low enough to sit on a high-speed line without meaningfully loading it. The PESD3V3Z1BSFYL stands just 320µm high, is rated to a 150°C junction temperature, is RoHS compliant and ships on tape and reel in 9000-piece quantities.

A 3.3V standoff with sub-picofarad capacitance targets the fastest interfaces on a board: USB and other high-speed serial links, display and camera lanes, antenna feeds and radio-frequency front ends, where a conventional suppressor would attenuate and reflect the signal. The 0201 body allows placement directly at the connector pin, which is what makes the protection effective. Handset, module and high-speed digital board designers buy these in very high reel volumes. Note that this part carries a declared REACH SVHC substance.
