Introduction

The ESD441 is a unidirectional ESD protection diode for protecting data lines and other I/O ports. The ESD441 is rated to dissipate ESD strikes up to ±30 kV per the IEC 61000 - 4 - 2 international standard (greater than Level 4). This device features a 1 pF (typical) IO capacitance enabling high - speed interfaces protection for protocols such as USB 2.0. The extremely low dynamic resistance (0.1 Ω) and clamping voltage (7.6 V at 16 TLP) is specified for system level protection against transient events. The 30 kV ESD rating and 6.2 A surge provides robust transient protection in a tiny package for protecting 5.5 V power rails in portable electronics and other space constrained applications such as wearables. The ESD441 is offered in the industry standard 0201 (DPL) package.
