Product details

Two-channel steering TVS for Ethernet PHY line protection

The Texas Instruments TPD2E001DRST-NM is a steering (rail-to-rail) TVS diode array designed to clamp overvoltage transients on high-speed differential signal lines. Its two unidirectional channels map directly to the transmit and receive pairs of a single 10/100 Ethernet port, with a reverse standoff voltage of 5.5V (max) that sits above a 3.3V supply rail yet below the typical PHY absolute maximum rating. The 11V minimum breakdown gives headroom for the clamping action without loading the signal during normal operation.

Package and rework — 6-SON with exposed pad

Housed in a 6-WDFN with exposed pad (also listed as 6-SON, 3x3 mm body), this part is surface-mount only. The pad pitch is fine enough that solder paste volume matters more than reflow profile.

For a BOM line protecting Ethernet ports on a multi-year production run, this part does not introduce obsolescence risk today.

Frequently asked questions

Is TPD2E001DRST-NM suitable for 10/100 Ethernet protection?

Yes. The two unidirectional channels cover the TX and RX differential pairs of a single 10/100 Ethernet port. The steering (rail-to-rail) topology clamps transients to the supply rails, which is the standard approach for PHY-side protection on 3.3V or 5V biased lines. The 5.5V reverse standoff keeps the diode out of conduction during normal signal swings.

What is the difference between TPD2E001DRST-NM and TPD2E001DRLR?

The two parts share the same TPD2E001 die and electrical specs — both are 2-channel steering TVS arrays. The difference is the package: TPD2E001DRST-NM comes in a 6-SON (3x3) with exposed pad, while TPD2E001DRLR is in a smaller SOT-5X3 (1.6x1.6 mm) package. The SON variant offers better thermal dissipation through the pad, which matters if the application sees repetitive surge events; the SOT variant saves board area for space-constrained designs. Pinout differs between the two packages, so a direct PCB swap is not possible without a layout change.
