Protection ratings — 5V rail, 14V clamp, 6A pulse
The D5V0L4B5SO-7: That clamping voltage keeps downstream 5V logic and transceivers inside their absolute-maximum ratings during an ESD or surge event. The 84W peak pulse power rating (8/20µs) confirms the energy-handling capacity for short-duration transients typical of ESD and cable discharge events.
Four bidirectional channels in one SOT-25
Four bidirectional Zener channels are integrated into a single SC-74A / SOT-753 package, supplied as SOT-25. Each channel clamps symmetrically, so polarity does not matter — useful for protecting differential signal pairs or I/O lines where the signal swings above and below ground. The 15pF capacitance (at 1MHz) is low enough to avoid loading high-speed interfaces like USB 2.0, HDMI, or LVDS without significant signal degradation. Operating temperature range spans -65°C to 150°C (junction), covering industrial, automotive under-hood, and military-temperature applications.
