Rail-to-rail steering for high-speed data lines
The TPD4E05U06QDQARQ1 is a four-channel steering (rail-to-rail) TVS diode array from Texas Instruments, designed to clamp ESD transients on high-speed differential data lines such as HDMI and USB ports. Each of the four unidirectional channels routes the surge current to the supply rail or ground, keeping the protected IC within its safe operating area.
Automotive-grade transient protection
This part carries AEC-Q101 qualification, making it suitable for automotive electronics where reliability under temperature cycling and vibration is mandatory.
Clamping performance and package fit
The clamping voltage at peak pulse current is 14 V (max), and the device handles 2.5 A of peak pulse current (8/20 µs waveform) with a peak pulse power rating of 40 W.
