Rail-to-rail steering for high-speed data lines
The SRV05-4MR6T1G is a steering (rail-to-rail) TVS diode array from onsemi, designed to clamp transient overvoltages on four unidirectional channels while keeping signal integrity intact on high-speed interfaces. With a typical capacitance of just 3 pF at 1 MHz, it loads the data line minimally — a fit for USB 2.0, HDMI, or LVDS paths where added capacitance would round off the signal edges. The 5 V reverse standoff (max) and 17.5 V clamping (max at Ipp) mean it triggers below the damage threshold of 3.3 V and 5 V logic families, shunting the surge to the supply rails.
300 W peak pulse — what it buys you
Rated for 300 W peak pulse power (8/20 µs waveform), the array handles the energy of a typical ESD strike or cable discharge event without the part failing short — the clamp absorbs the transient, not the downstream IC.
