With a peak pulse power rating of 35W, this array clamps fast transients on data lines, I/O ports, and power rails where board space is tight. The Zener structure provides low clamping voltage relative to the 3V standoff, minimising stress on protected ICs. Note that power line protection is not supported — this array is intended for signal-level ESD clamping, not AC mains or high-energy surge suppression. No direct replacement or second-source is recorded on this line — the base product number TPD4E002 covers the family, and the DRLR suffix specifies the SOT-553 reel variant.","metaTitle":"TPD4E002DRLR Zener ESD Protection Array - TI, SOT-553, 4-Ch","metaDescription":"Texas Instruments TPD4E002DRLR Zener diode array for ESD protection. 4 unidirectional channels, 35W peak pulse, SOT-553.
