Applications
The TPD1E1B04DPYT protects single I/O lines in smartphones, tablets, and wearable devices against ESD events that can destroy input-stage transistors. It is also used on USB, HDMI, and other data lines in consumer accessories where board area is scarce and the ultra-compact 2-pin SOD-523 package is required. Low-voltage microcontroller GPIO pins in industrial handheld scanners benefit from its 6.4 V clamping characteristic.

Frequently Asked Questions
What is the clamping voltage of the TPD1E1B04DPYT, and how does it relate to a 5 V I/O rail?
The TPD1E1B04DPYT clamps transients to a maximum of 6.3 V, which keeps the protected node safely above a 5 V logic rail during normal operation while suppressing ESD peaks before they reach damaging levels. The 6.4 V breakdown voltage ensures the diode stays off during normal 5 V signaling.
How many channels does the TPD1E1B04DPYT protect, and in which package does it come?
The device is a single-channel, 1-line bidirectional TVS diode housed in the 2-pin SOD-523 (DPY) package. Its footprint occupies less than 1 mm² of PCB area, making it suitable for protecting individual lines in wearable electronics and compact mobile accessories.
For which interface lines is the TPD1E1B04DPYT typically recommended as an ESD guard?
The TVS diode is well-suited for protecting USB data lines, HDMI channel signals, GPIO pins, and other low-voltage serial interfaces running at or below 5 V. Its low 6.3 V clamp and bidirectional silicon construction handle both positive and negative ESD transients on single-wire I/O lines.
How does the TPD1E1B04DPYT compare to multi-channel ESD arrays for protecting a single I/O line?
For a single protected line, the TPD1E1B04DPYT avoids paying for unused channels in a multi-line array package. The 2-pin SOD-523 body is smaller than any 4- or 6-pin array, saving board space and reducing parasitic capacitance on the protected signal — an important factor for high-speed USB 2.0 at 480 Mbps.
