PI3USB4002AZUAEX

Overview

The PI3USB4002AZUAEX is a differential bi-directional SPST switch and high voltage short/surge protector manufactured by Diodes Incorporated. It supports USB 2.0 signals with a 1 GHz bandwidth and operates on a single supply voltage of 2.7V to 5.5V. The device features an ultra-low ON resistance (Ron) of 5Ω typical and 9Ω maximum, alongside an ultra-low ON capacitance (Con) of 7pF. It provides over-voltage protection at 4.75V, allowing C0+/C0- pins to tolerate voltages up to 24V while L0+/- and VDD tolerate up to 6V. The component is housed in a 10-contact UQFN package measuring 1.5x2mm.

Feature Summary

High voltage tolerance for C0+/C0- pins up to 24V with integrated over-voltage protection switching off channels at 4.75V
Ultra-low signal distortion characteristics including 7pF ON capacitance and 1GHz bandwidth for maintaining USB 2.0 signal integrity
Robust ESD protection rated at 10kV per IEC61000-4-2 standards on data lines

Applications

Smartphones
USB-C applications
Tablets
Notebooks
Personal computers

Procurement Notes

Verify the ordering code matches the specific suffix requirements for your manufacturing needs. The 'ZUA' indicates the 10-pin UQFN package, while 'EX' denotes tape and reel packaging. Confirm that the component meets RoHS and halogen-free compliance standards required by your assembly specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring protection against high voltage surges on USB ports while maintaining high-speed signal transmission. It is suitable for systems needing a single-channel switch with low insertion loss and high isolation. Ensure the design accommodates the 1uF capacitor requirement on the REF pin for proper operation within the specified temperature range.

Part Context

This part belongs to the PI3USB4002A product line from Diodes Incorporated, designed specifically as a USB interface protection IC. It serves as a specialized solution for managing power delivery and signal integrity in portable electronic devices. The device integrates both switching functionality and robust protection mechanisms into a compact footprint.

Replacement Considerations

The PI3USB4002A is the base model for this component. Verify if alternative packages or suffixes are available from the manufacturer if different reel quantities or minor packaging variations are required for your production line.

FAQ

What is the function of the REF pin?

The REF pin serves as a reference input and must be connected to ground through a 1uF capacitor with a voltage rating higher than the maximum voltage applied to the C0+/C0- pins.

How does the device handle over-voltage conditions?

The device implements over-voltage protection (OVP) that triggers at 4.75V, immediately switching off the channels to protect the system side when an over-voltage condition is detected on the port side.
