ESD441DPYR

ESD441 is a unidirectional ESD protection diode designed to protect data lines and other I/O ports. Compliant with the IEC 61000-4-2 international standard, it is rated to dissipate ESD strikes up to ±30kV, exceeding Level 4. The device features a typical I/O capacitance of 1pF, enabling protection for high-speed interfaces such as USB 2.0. For system-level protection against transient events, the device is specified with an ultra-low dynamic resistance of 0.1Ω and a clamping voltage of 7.6V at 16A TLP. The 30kV ESD rating and 6A surge capability deliver reliable transient protection in an ultra-compact package, safeguarding 5.5V power rails in space-constrained applications such as portable electronics and wearables. ESD441 is available in industry-standard 0201 and 0402 packages.
