What are the key features of TPD4E001DPKR?
- ±15 kV IEC 61000-4-2 contact discharge rating on all 4 channels protects USB, HDMI, and other high-speed data lines from damaging ESD events
- Ultra-low capacitance per channel minimizes signal distortion on high-speed differential pairs running at 480 Mbps or higher
- 25 V maximum clamping voltage with 11 V minimum breakdown keeps transient energy away from sensitive downstream ICs
What is TPD4E001DPKR used for?
TPD4E001DPKR is designed to protect four I/O lines in USB 2.0, UART, and general-purpose serial interfaces in smartphones, tablets, and portable consumer electronics against electrostatic discharge events up to ±15 kV. Its compact SOT-363 footprint consumes minimal PCB space near exposed connectors such as USB, audio jacks, or SIM card slots. The device is also suitable for protecting display data lines, touchscreen interfaces, and Bluetooth antenna lines in wearables.

Frequently Asked Questions
What ESD protection level does TPD4E001DPKR provide, and which industry standard does it meet?
TPD4E001DPKR is rated for ±15 kV contact discharge and ±15 kV air discharge per IEC 61000-4-2, the most widely referenced ESD immunity standard for industrial and consumer electronics. It also meets JEDEC JESD22-A114 Human Body Model and Machine Model test requirements. With a clamping voltage of 25 V maximum, the device effectively limits transient spikes to safe levels for downstream MCUs and interface ICs operating at 1.8 V to 5 V logic levels.
How does the channel capacitance of TPD4E001DPKR affect signal integrity on USB 2.0 and similar high-speed lines?
TPD4E001DPKR has a very low per-channel capacitance, typically around 0.35 pF, which introduces negligible signal attenuation and reflections on USB 2.0 data lines operating at 480 Mbps. By comparison, a general-purpose TVS diode may have 10 pF to 100 pF capacitance, which would significantly degrade high-frequency differential signal integrity. The low 0.35 pF capacitance also makes the device compatible with faster interfaces such as HDMI 1.4 and MIPI D-PHY without degrading eye diagram margin.
For a compact smartphone PCB, how much space does TPD4E001DPKR require compared to 4 discrete TVS diodes?
TPD4E001DPKR integrates 4 ESD protection channels in a single SOT-363 package measuring approximately 2 mm × 2 mm, occupying around 4 mm² of board area. Replacing 4 individual SOD-323 TVS diodes (each roughly 1.7 mm × 1.25 mm) would need at least 8.5 mm² plus routing clearance between components. The single-package solution thus saves more than 50% of board area on ESD protection while simplifying assembly from 4 discrete placements to 1, reducing component cost and pick-and-place cycle time.
