Description
The TPD4S009DGSR is a 4-channel ESD protection diode array from Texas Instruments, designed to safeguard sensitive electronics from electrostatic discharge (ESD), electrical fast transients (EFT), and surge events. Key features include:
- Low clamping voltage (8V at 3A) for robust protection.
- Ultra-low leakage current (1nA max) to minimize power loss.
- Small DFN-10 package (3mm × 3mm), ideal for space-constrained designs.
- IEC 61000-4-2 compliance (±15kV air-gap, ±8kV contact discharge).
Commonly used in USB ports, HDMI interfaces, and other high-speed data lines, it ensures reliable operation in consumer electronics, industrial systems, and automotive applications.

Pinout
The TPD4S009DGSR is a 10-pin (DGS package) USB ESD protection diode designed for high-speed interfaces like USB 2.0, HDMI, and DisplayPort.
Key Functions:
1. ESD Protection – Safeguards against electrostatic discharge (IEC 61000-4-2, ±8kV contact, ±15kV air).
2. Low Capacitance – ~0.6pF per channel to minimize signal distortion.
3. 4-Channel Protection – Protects 4 data lines (e.g., USB D+/D–, HDMI differential pairs).
4. Integrated Pull-Down Resistors – Helps with hot-plug detection (e.g., for HDMI).
Pinout Highlights:
- Pins 1–4: Protected I/O lines (e.g., D1+ to D4+).
- Pins 5–8: Corresponding return paths (e.g., D1– to D4–).
- Pin 9: Ground (GND).
- Pin 10: No connect (NC).
Applications: USB ports, HDMI, DisplayPort, and other high-speed data lines.
