Semtech RClamp1654P
RailClamp® 低电容 TVS 阵列
The RClamp1654P is specifically designed to protect portable devices that utilize the USB port for battery charging. The unique design of this device features low capacitance TVS diodes for protection of the USB data(DP, DM) and USB ID (accessory detect) pins operating up to 5 volts. Loading capacitance on these lines is <1pF for maximum signal integrity. An integrated 12 volt TVS diode is used for protection of the USB voltage bus.
