Texas Instruments TPD4E110DPWR

Overview

TPD4E110DPWR from Texas Instruments is a unidirectional ESD protection diode array designed for high-speed differential signal lines, featuring 0.45 pF typical channel capacitance, ±12 kV contact/±15 kV air-gap IEC 61000-4-2 ESD rating, and 6.5 V minimum DC breakdown voltage. It protects four independent IO channels (IO1–IO4) referenced to GND in USB 3.0, HDMI 2.0, and PCIe interfaces.

For engineers reviewing the TPD4E110DPWR datasheet, TPD4E110DPWR pinout, TPD4E110DPWR application, or TPD4E110DPWR equivalent, key selection criteria include ultra-low capacitance for >6 Gbps data integrity, low dynamic resistance (0.7–0.8 Ω), clamping voltage ≤13 V at 5 A TLP, and compatibility with space-constrained 0.8 mm × 0.8 mm X2SON packaging.

Technical Context

The TPD4E110DPWR employs a central ESD clamp architecture with two series-hiding diodes per channel to minimize capacitive loading while maintaining fast response (<10 ns) during ±15 kV ESD transients. Its passive operation triggers only when line voltage exceeds 6.5 V (breakdown) or drops below –0.6 V (forward conduction), diverting surge current to GND.

Each of the four identical IO channels supports 0–5.5 V signal swing and exhibits matched capacitance variation (ΔCIO-TO-GND ≤ 0.05 pF), enabling precise differential pair routing without skew. The device operates across –40°C to 125°C and sustains 2.5 A (8/20 µs) IEC 61000-4-5 surge events with peak pulse power up to 35 W forward.

Key Specifications

Pinout & Package

The TPD4E110DPWR uses a 4-terminal X2SON (DPW) package measuring 0.8 mm × 0.8 mm with 0.4 mm maximum height and an exposed thermal pad. Pin 1 index is marked on top; orientation follows Q2 quadrant convention. Thermal pad must be soldered for mechanical stability and thermal performance.

FAQ

What is the maximum data rate supported by TPD4E110DPWR?

The TPD4E110DPWR supports data rates up to 6 Gbps, validated via insertion loss measurements showing <1 dB attenuation at 3 GHz and eye diagram compliance in USB 3.0 SuperSpeed applications. Its 0.45 pF typical channel capacitance and matched inter-channel capacitance (≤0.05 pF) ensure minimal signal distortion at these speeds.

Does TPD4E110DPWR require external biasing or control signals?

No, the TPD4E110DPWR is a fully passive ESD protection device with no external bias or enable requirements. It operates automatically when transient voltages exceed its 6.5 V breakdown threshold or drop below –0.6 V forward conduction level, making it compatible with any 0–5.5 V IO interface without additional circuitry.

Can TPD4E110DPWR protect bidirectional differential signals like USB 3.0 SSTX+/SSTX–?

Yes, the TPD4E110DPWR's unidirectional architecture protects each IO line relative to GND, allowing it to safeguard both polarities of differential pairs. In USB 3.0, IO1 and IO2 are assigned to SSTX+ and SSTX– respectively, with both referenced to the same GND terminal - maintaining differential mode integrity while suppressing common-mode ESD transients.

What is the recommended PCB layout practice for TPD4E110DPWR?

Place the TPD4E110DPWR as close as possible to the connector - ideally within 5 mm - to minimize unprotected trace length. Route protected lines straight with rounded corners (≥0.5 mm radius), avoid vias between the device and connector, and solder the thermal pad to a solid ground plane. For USB 3.0, this enables single-layer routing of two differential pairs using 2.8 mil traces.

Is TPD4E110DPWR compliant with automotive AEC-Q200 standards?

No, the TPD4E110DPWR is not AEC-Q200 qualified. It is rated for industrial temperature range (–40°C to 125°C) and meets IEC 61000-4-2 Level 4 and IEC 61000-4-5 surge standards, but lacks the stress testing, failure analysis, and qualification documentation required for automotive-grade deployment. For automotive applications, consider TI's AEC-Q200 qualified alternatives such as TPD4E001DPYR.
