Its 3.3V reverse standoff voltage matches common low-voltage logic rails (3.3V LVCMOS, LVDS, HDMI), so the diode array sits directly on the signal path without extra level shifters. Eight unidirectional channels in a single 10-MSOP package pack protection for an entire 8-bit bus or four differential pairs into a 3×3 mm footprint — a density that matters when board real estate is tight. ## Clamping performance and pulse handling Typical clamping voltage is 8.8V at 1A peak pulse (8/20 µs waveform). That 8.8V ceiling stays well below the 5V absolute maximum of most 3.3V ASICs, giving a solid margin for ESD events. Minimum breakdown voltage is 6V, meaning the device triggers before the protected IC's internal ESD diodes conduct — the steering action shunts the transient to the rail before it reaches the die.","metaTitle":"CM1213-08MR onsemi Steering (Rail to Rail) TVS Diode Array","metaDescription":"CM1213-08MR onsemi steering rail-to-rail TVS array, 8 unidirectional channels, 3.3V standoff, 10-MSOP.
