The PESD3V3S1UB.115 part of Nexperia is a discrete dual mono ESD protection diode in a small SOT-23 package. It provides ESD protection to signal lines up to 8kV Contact Discharge, and has an unusually low profile, making it ideal for thin, slim, or tight-fitting designs. The two separate monoflops act as two individual diodes in a single package, helping to reduce assembly times and making the most of board space. This device has a very low maximum clamping voltage and low forward voltage drop, which helps improve signal integrity and minimize power dissipation. It is suitable for a wide range of consumer-facing products, including USB, HDMI, and TV shielding.
