PI3USB4002AQ1ZUAEX

Overview

The PI3USB4002AQ is an ultra-high voltage protection USB 2.0 SPST switch manufactured by Diodes Incorporated. It features a differential bidirectional architecture with a wide input voltage range of 0V to 5.5V and a supply voltage of 2.7V to 5.5V. The device provides over-voltage protection (OVP) at 4.75V, ensuring immediate channel shutdown during high-voltage events. Key electrical parameters include a typical on-resistance (Ron) of 5Ω, a -3dB bandwidth of 1GHz, and ultra-low capacitance values: Con of 7pF and Coff of 9pF. It operates within a temperature range of -40°C to 125°C and is packaged in a 10-contact UQFN (ZUA) measuring 1.5x2mm.

Feature Summary

Ultra-high voltage tolerance for C0+/C0- pins up to 24V and L0+/- pins up to 6V
Integrated over-voltage protection that switches off channels when Vbus exceeds 4.75V
High-speed signal integrity maintained through 1GHz bandwidth and low propagation delay
AEC-Q100 qualified for automotive applications requiring specific change control

Applications

Smart Phones
USB-C Applications
Tablets
Notebooks
PCs

Procurement Notes

Verify the component against the official datasheet DS41995 Rev 2-2 to confirm authenticity. Ensure the ordering suffix matches the required package and tape/reel specifications. Confirm AEC-Q100 qualification status if deploying in automotive environments. Validate that the supplier sources from authorized channels to avoid counterfeit parts.

Selection Notes

Select this component for designs requiring robust protection against high-voltage surges on USB data lines. The 24V tolerance on the port side makes it suitable for hot-plug scenarios involving non-standard power delivery. Consider the 1.5x2mm UQFN package for space-constrained layouts. Ensure the REF pin is decoupled with a capacitor rated higher than the maximum expected voltage on the C0± pins.

Part Context

This part belongs to the PI3USB4002 family of high-voltage USB switches. Unlike standard switches, the AQ variant is specifically engineered for automotive-grade reliability and enhanced voltage tolerance. It complements other interface ICs in the portfolio by providing critical protection for downstream components against electrical overstress.
