The SGM40679A has two symmetrical paths, which is designed for match with the differential transmission pairs for USB Type-C transmission stripe lines. When the voltage on the DN pin or the DP pin exceeds the typical common-mode range, the paths will be disconnected to ensure that no high direct current voltage is transmitted separately to the DSN pin or the DSP pin. 

This SGM40679A is biased between the VCC and GND pins with a low current, and the bias voltage range is from 2.3V to 5.5V. When the two paths are biased to 1V by the Type-C receiver or the transmitter without DC isolation capacitors, the performance is guaranteed. 

The SGM40679A is available in a Green WLCSP- 0.75×1.1-6B package.
