The PESD2V8Y1BSF from Nexperia is a Bidirectional ESD Protection Diode that is designed to protect a single bidirectional data line from surge pulses and ESD-related damages. This protection diode has a reverse voltage from -2.8 V to +2.8 V. It is suitable on lines where the signal polarities are both positive and negative for the ground. This diode uses an advanced clamping structure that provides a negative dynamic resistance. It exhibits snap-back behavior which helps in reducing the clamping voltage to the system behind the ESD protection limit during an ESD event. This diode is available in a surface-mount package that measures 0.6 x 0.3 x 0.3 mm and is ideal for cellular handsets and accessories, portable electronics, computers and peripherals, USB 4, USB 3.2, Thunderbolt 3, and 4 data lines, and communication system applications.
