Three-channel rail-to-rail steering diode array for general-purpose ESD protection
Power line protection is included, making it suitable for clamping on supply rails as well as signal lines.
Active lifecycle — no near-term LTB risk for production BOMs
The base product number is TPD3E001, so any future package or tape-and-reel variant changes would carry the same die and electrical characteristics.
90W peak pulse — sizing the clamp for your transient budget
For a 5.5V rail, a 90W clamp translates to roughly 16A peak pulse current before the device exceeds its thermal limit. That is adequate for typical ESD strikes and small induced surges on low-voltage signal lines, but not for direct lightning or high-energy industrial transients. If your application sees repetitive surges or higher energy, you would need a larger TVS or a multi-stage protection scheme.
SOT-553 footprint — board-area and assembly considerations
The SOT-553 package (supplier device package SOT-5) is a very small 5-pin surface-mount package, roughly 1.6 mm × 1.6 mm.
