Overview
The TPD1E1B04 is a bidirectional TVS (Transient Voltage Suppressor) ESD protection diode designed by Texas Instruments. This device is notable for its ultra-low dynamic resistance (RDYN) and extremely low clamping voltage, making it ideal for protecting sensitive signal pins against transient events. The TPD1E1B04 is rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4), ensuring robust protection for high-speed interfaces such as USB 2.0.
