The TPD1E1B04 is a bidirectional TVS ESD protection diode featuring low RDYN and low clamping voltage. The TPD1E1B04 is rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4). The ultra-low dynamic resistance (0.15 Ω) and extremely low clamping voltage (8.5 V at 16-A TLP) ensure system level protection against transient events. This device features a 1-pF IO capacitance making it ideal for protecting interfaces such as USB 2.0. The TPD1E1B04 is offered in the industry standard 0402 (DPY) package.
