Product details

Two-channel rail-clamp ESD protection in a SOT-553

The Texas Instruments TPD2E001DRLRG4 is a steering (rail-to-rail) TVS diode array packing two unidirectional protection channels into a single SOT-553 package. The rail-to-rail topology keeps the capacitance low, making it suitable for preserving signal integrity on interfaces like Ethernet.

The 11 V breakdown triggers only during an ESD event, shunting the surge to the supply or ground rail through the steering diodes.

SOT-553 footprint and placement

The SOT-553 package (also listed as supplier device package SOT-5) is a 5-lead package. Two channels in this footprint mean one device protects a differential pair or two single-ended lines.

Frequently asked questions

Is TPD2E001DRLRG4 suitable for Ethernet protection?

Yes, the TPD2E001DRLRG4 is listed for Ethernet applications. Its low-capacitance steering topology and 5.5 V standoff voltage protect the differential signal pairs without degrading signal integrity at 100BASE-TX or 1000BASE-T data rates.

How many channels does TPD2E001DRLRG4 have?

This device has two unidirectional channels, each capable of protecting one signal line. Two channels in one SOT-553 package cover a differential pair or two single-ended lines.

What is the difference between TPD2E001DRLR and TPD2E001DRLRG4?

The suffix 'G4' on the TPD2E001DRLRG4 indicates RoHS compliance and a green (halogen-free) molding compound. The TPD2E001DRLR variant may be non-RoHS or an earlier environmental compliance level. Electrically and functionally the two are identical.
