Overview
The TPD1E10B09DPYT is a single-channel electrostatic discharge (ESD) protection device manufactured by Texas Instruments. This device is designed to provide system-level ESD protection for I/O interfaces and is packaged in a compact 0402 footprint, making it ideal for space-constrained applications. The TPD1E10B09 features a back-to-back transient voltage suppression (TVS) diode configuration, which supports bipolar or bidirectional signal lines. It is suitable for protecting a wide range of electronic devices from ESD strikes and surge pulses.
