Two-channel steering TVS for automotive signal-line protection
The Texas Instruments TPD2E001IDRLRQ1 is a steering (rail-to-rail) TVS diode array with two unidirectional channels, designed to clamp ESD transients on high-speed data lines such as automotive Ethernet. The reverse standoff voltage is rated at 5.5V max, with a minimum breakdown of 11V, so it protects 3.3V and 5V signal rails without loading them during normal operation.
SOT-553 footprint and power-line protection
Housed in a SOT-553 package (supplier device package SOT-5), the part occupies minimal board area — useful when routing differential pairs near the connector. Power line protection is integrated, so the same device can clamp both signal and supply lines in a single package.
