Four-channel ESD clamp in a SOT-353 footprint
The D5V0L4B5S-7 is a four-channel bidirectional Zener TVS from Diodes Incorporated, packing four independent ESD protection paths into a five-pin SOT-353 package.
Peak pulse current and capacitance budget
Each channel handles a peak pulse current of 6 A under the 8/20 µs waveform, with a peak pulse power dissipation of 84 W. The 15 pF capacitance per channel at 1 MHz is low enough for high-speed data lines — USB 2.0, HDMI, or LVDS interfaces — where excessive loading would degrade signal edge rates. The device does not include power line protection; it is designed for signal-line ESD clamping where the 6 A pulse rating covers IEC 61000-4-2 level 4 contact discharge events without latch-up or degradation.
SOT-353 integration for dense boards
The SOT-353 (SC-70-5) package occupies roughly 2.0 mm × 2.1 mm, fitting four protected channels in the footprint of a single small-signal transistor.
