Low-Capacitance, 2/3/4/6-Channel, ±15kV ESD-Protection Arrays for High-Speed Data Interfaces

Lowest Capacitance 2-/3-/4-/6-Channel ESD-Protection Arrays in WLP

Please check latest availability status for a specific part variant.


The MAX3202E/MAX3203E/MAX3204E/MAX3206E are low-capacitance ±15kV ESD-protection diode arrays designed to protect sensitive electronics attached to communication lines. Each channel consists of a pair of diodes that steer ESD current pulses to VCC or GND. The MAX3202E/MAX3203E/MAX3204E/MAX3206E protect against ESD pulses up to ±15kV Human Body Model, ±8kV Contact Discharge, and ±15kV Air-Gap Discharge, as specified in IEC 61000-4-2. These devices have a 5pF capacitance per channel, making them ideal for use on high-speed data I/O interfaces.

The MAX3202E is a two-channel device intended for USB and USB 2.0 applications. The MAX3203E is a triple-ESD structure intended for USB On-the-Go (OTG) and video applications. The MAX3204E is a quad-ESD structure designed for Ethernet and FireWire® applications, and the MAX3206E is a six-channel device designed for cell phone connectors and SVGA video connections.

All devices are available in tiny 4-bump (1.05mm x 1.05mm) WLP, 6-bump (1.05mm x 1.57mm) WLP, 9-bump (1.52mm x 1.52mm) WLP, 6-pin (3mm x 3mm) TDFN, and 12-pin (4mm x 4mm) TQFN packages and are specified for -40°C to +85°C operation.
