Typical Applications
TPD2E001DRLR is suitable for 6 applications: USB Port Protection, Ethernet Interface Protection, LVDS Display Protection, HDMI Port Protection, Industrial Sensor Interfaces, Consumer Electronics I/O Protection.
USB Port Protection
The TPD2E001DRLR protects USB 2.0 ports from ESD events. Its low capacitance of 1.5 pF ensures minimal signal degradation on the D+ and D- lines, maintaining USB 2.0 signal integrity. The device clamps ESD strikes up to ±8 kV (contact) per IEC 61000-4-2, safeguarding the downstream controller. Placed near the connector, it diverts transient energy to ground, preventing damage to the USB transceiver. This makes it ideal for consumer electronics like smartphones, laptops, and peripherals.
Recommended
Ethernet Interface Protection
The TPD2E001DRLR is suitable for protecting Ethernet PHY interfaces from ESD. With a working voltage of 5.5 V and clamping voltage of 16 V, it handles transient events on the differential pairs. The low capacitance minimizes signal distortion on high-speed Ethernet lines, supporting 10/100/1000 Mbps data rates. It is often placed between the magnetics and the PHY to protect against ESD from cable discharges. This application is common in industrial networking equipment, routers, and switches.
Recommended
LVDS Display Protection
The TPD2E001DRLR protects LVDS display interfaces from ESD. Its 1.5 pF capacitance is low enough to preserve the high-speed differential signals used in LVDS, ensuring no degradation in display quality. The device clamps ESD events up to ±15 kV (HBM), protecting the display driver IC. It is typically placed near the LVDS connector on the PCB. This is critical in applications like automotive infotainment, medical monitors, and industrial displays where reliability is paramount.
Recommended
HDMI Port Protection
The TPD2E001DRLR can be used to protect HDMI ports from ESD. Although HDMI has 4 differential pairs, the TPD2E001DRLR can be used on the control pins (DDC, CEC, HPD) or as part of a multi-device solution. Its low capacitance ensures minimal impact on the high-speed TMDS signals. The device's ESD rating of ±8 kV (contact) meets HDMI compliance requirements. It is commonly used in set-top boxes, TVs, and gaming consoles to enhance reliability.
Recommended
Industrial Sensor Interfaces
The TPD2E001DRLR protects industrial sensor interfaces from ESD and transient voltages. Its wide operating temperature range of -40°C to +125°C makes it suitable for harsh industrial environments. The device can protect RS-485, CAN, or other serial interfaces used in factory automation. With a clamping voltage of 16 V, it ensures that transients do not damage sensitive microcontrollers or transceivers. This enhances the reliability of industrial control systems.
Recommended
Consumer Electronics I/O Protection
The TPD2E001DRLR is ideal for protecting various I/O ports in consumer electronics, such as audio jacks, memory card slots, and debug ports. Its small SOT-5 package allows for easy placement near connectors. The low capacitance ensures minimal signal distortion for audio and data signals. The device provides robust ESD protection up to ±15 kV (HBM), safeguarding the internal circuitry. This is essential for smartphones, tablets, and wearables to meet reliability standards.

Key Differentiators
- Low capacitance of 1.5 pF (vs TPD2E2U06DRLR)
- VCC pin for biasing (vs TPD2E2U06DRLR)
- Wide availability and legacy support (vs LC0542T5)
Design Notes
Place the TPD2E001DRLR as close as possible to the connector or I/O port to minimize trace length and inductance. This ensures effective clamping of ESD events. Use short, wide traces to the protected lines and a solid ground connection to the GND pin. Avoid vias between the device and the protected lines to reduce parasitic inductance.
For high-speed interfaces, ensure the differential pair traces maintain controlled impedance. The low capacitance of the TPD2E001DRLR (1.5 pF) minimizes loading, but keep the stub length from the main trace to the device as short as possible. This is especially important for USB 2.0 and Ethernet to avoid signal reflections.
Do not exceed the working voltage of 5.5 V on the protected lines, as this may cause the device to conduct and affect normal operation. The VCC pin can be left floating, but connecting it to the supply rail can improve clamping performance. Ensure the device is not subjected to continuous overvoltage conditions, as it is designed for transient protection only.
