LS05006VPQ33

Overview

The LS05006VPQ33 is a board-mount surge protector designed for USB Type-C port protection. It safeguards CC and SBU lines against short-to-VBUS events, overvoltage up to 24 V, and ESD. The device features a 5 V voltage rating, 600 mA current rating, and 50 pF capacitance. It operates within a temperature range of -40°C to +150°C. Packaged in a QFN-20 footprint measuring 3.1 mm x 3.1 mm with a height of 0.8 mm, it supports surface mount installation.

Feature Summary

• Protects downstream low-voltage silicon circuits from overvoltage and IEC61000-4-2 ESD shocks
• Includes an integrated CC pin pull-down resistor for battery-depleted device charging support
• Automatically disconnects the internal pull-down resistor upon system power-up to prevent control conflicts

Applications

• USB Type-C devices
• Laptops
• Desktop computers
• Monitors
• Industrial computers
