Key Features
- Ultra-compact 2-pin X1SON package at 0.62 mm x 0.62 mm occupies the minimum board space of any single-channel ESD diode
- 3.6 V DC standoff voltage and 8.5 V clamping voltage provide tight clamping for 3.3 V I/O lines including USB, HDMI, and MIPI
- Bidirectional protection topology handles both positive and negative ESD transients without polarity-sensitive mounting
- Low capacitance below 0.25 pF preserves signal integrity on high-speed data lines up to multi-gigabit rates
Applications
TPD1E1B04DPYR is designed to protect ESD-sensitive I/O pins on mobile devices, tablets, and wearables where board space is at an absolute premium. It is commonly placed on USB, MIPI CSI/DSI, HDMI, and other high-speed differential signal lines that connect to external connectors exposed to ESD events during handling. Its sub-0.25 pF line capacitance ensures minimal impact on signal integrity at data rates up to 10 Gbps.

Frequently Asked Questions
What clamping voltage does TPD1E1B04DPYR achieve during an IEC 61000-4-2 ESD event?
TPD1E1B04DPYR clamps to a maximum of 8.5 V during an IEC 61000-4-2 Level 4 ESD event (±8 kV contact discharge), protecting downstream ICs with I/O voltage tolerances of 3.3 V or higher. The 3.6 V standoff voltage ensures the diode remains off during normal signal operation, preventing any loading on the protected signal line.
How does the X1SON package size of TPD1E1B04DPYR compare to SOD-323 ESD diodes?
The 2-pin X1SON package of TPD1E1B04DPYR measures only 0.62 mm x 0.62 mm, which is approximately 8 times smaller in footprint than the SOD-323 package at about 1.7 mm x 1.25 mm. This size difference is critical for ultra-thin smartphones and wearable PCBs where protecting 10 or more I/O lines with SOD-323 devices would consume over 21 mm² versus under 4 mm² using X1SON devices.
Can TPD1E1B04DPYR be used to protect USB 3.2 or MIPI high-speed differential signal lines?
Yes. TPD1E1B04DPYR has a line capacitance below 0.25 pF, which introduces negligible signal degradation on differential pairs operating at multi-gigabit data rates such as USB 3.2 Gen 2 at 10 Gbps or MIPI D-PHY at 4.5 Gbps per lane. The 3.6 V standoff voltage is compatible with 3.3 V differential signaling standards, and the bidirectional structure handles both positive and negative swings equally.
How many TPD1E1B04DPYR devices are needed to protect a 4-lane MIPI CSI-2 camera interface?
A 4-lane MIPI CSI-2 interface has 4 differential data pairs plus 1 clock pair, totaling 10 individual signal pins. You would need 10 TPD1E1B04DPYR devices to protect all single-ended lines, or 5 dual-channel ESD devices if board space allows. At 0.62 mm x 0.62 mm each, 10 X1SON devices consume only about 3.8 mm² of PCB area, which is feasible even in smartphone camera modules.
