Overview
The TPD1E01B04DPYT is a 1-channel ESD protection diode designed by Texas Instruments for protecting high-speed interfaces such as USB Type-C and Thunderbolt 3. This bidirectional TVS (Transient Voltage Suppressor) diode is rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4). It features ultra-low capacitance, low dynamic resistance, and low clamping voltage, making it ideal for system-level protection against transient events.
