PESDR0521P1 is an electronic component manufactured by PN SILICON, which is a Transient Voltage Suppressor (TVS) Diode array designed for ESD and surge protection. It has a DFN1006-2 footprint, with dimensions of 1.0x0.6x0.5 mm, and is compliant with RoHS (Restriction of Hazardous Substances) standards. It has a very fast response time and low operating voltage. It has a peak pulse power rating of 6.0 W, and is typically used for protecting sensitive electronic components, such as power drivers, from electro-static discharge (ESD) and surge events.
