Overview
The ESD401DPYR is a bidirectional TVS (Transient Voltage Suppressor) ESD (Electrostatic Discharge) protection diode manufactured by Texas Instruments. This component is designed to safeguard sensitive electronic components from ESD damage and other transient voltage events. It features low dynamic resistance and low clamping voltage, making it ideal for protecting high-speed interfaces such as USB 2.0. The ESD401DPYR operates within an industrial temperature range of -40°C to 125°C and is packaged in a compact 2-X1SON package, which is RoHS compliant and has a moisture sensitivity level (MSL) of 1.
