PACUSBVB-D1Y6R

Overview

The PACUSBVB-D1Y6R is a single-channel USB downstream-port termination network by onsemi, designed for signal integrity and ESD protection. It integrates an EMI/RFI filter comprising resistor R1 and capacitor C1, alongside VBUS ESD protection diodes. The device operates within a voltage range of 3.0V to 3.6V (Vrwm) and features a low capacitance of 4.5 pF. Packaged in a compact SOT23-6 surface-mount format with dimensions of 0.445 x 0.24 mm, it supports USB D+/-, GPIO, and audio lines while ensuring compliance with USB specifications.

Feature Summary

• Integrates EMI/RFI filtering components directly into the termination network for enhanced signal quality.
• Provides robust electrostatic discharge protection for sensitive data and power lines.
• Utilizes a stacked architecture design to minimize physical footprint for space-constrained applications.

Applications

• USB Downstream Port Termination
• ESD Protection for USB Data Lines
• GPIO Line Protection

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm package marking and lot traceability against official datasheets. Check for obsolescence status as historical records indicate potential end-of-life phases. Ensure storage conditions comply with moisture sensitivity levels specified in the handling guidelines.

Selection Notes

Select this component when designing circuits requiring integrated termination and protection for USB interfaces. Consider the SOT23-6 package size for PCB layout constraints. Evaluate the 4.5 pF capacitance impact on high-speed signal integrity relative to specific USB standards. Ensure voltage ratings align with system VBUS requirements.
