# TPD2EUSB30DRTR: 2-Channel USB 3.0 TVS ESD Array (TI)

**Texas Instruments TPD2EUSB30DRTR** is a 2-channel TVS-based ESD protection array for
USB 3.0 SuperSpeed (5 Gbps) and other high-speed differential IO. Low 0.7 pF channel
capacitance and flow-through pin mapping keep it out of the way of the signal.

## Electrical (TPD2EUSB30, from SLVSAC2G)

| Parameter | Value |
|---|---|
| Channels | 2 (D+, D−), bidirectional TVS to GND |
| Reverse stand-off voltage V(RWM) | 5.5 V |
| Breakdown voltage V(BR) @ 1 mA | 7 V |
| Clamp voltage @ 1 A | 8 V |
| Dynamic resistance | 0.6 Ω typ |
| Capacitance IO→GND | 0.7 pF typ (DRT) |
| Capacitance IO→IO | 0.05 pF typ |
| IEC 61000-4-2 ESD | ±8 kV contact, ±8 kV air-gap |
| IEC 61000-4-5 surge | 5 A / 45 W peak (8/20 µs) |
| Operating temperature | −40 … 85 °C |

> The **TPD2EUSB30A** variant (same package, same footprint) drops V(RWM) to 3.6 V and
> V(BR) to 4.5 V. Use it where the protected rail never exceeds 3.6 V. This page is the
> plain **TPD2EUSB30**.

## Pinout

| Pin | Name | Type | Notes |
|---|---|---|---|
| 1 | D+ | passive | protected line |
| 2 | D− | passive | protected line |
| 3 | GND | passive | return for both TVS channels |

Flow-through mapping means the part drops straight onto a differential pair with no
stub. Place it as close to the connector as the layout allows and keep the GND pin's
via short and wide.

style and the footprint converted to modern KiCad syntax.
