The 9.9V reverse standoff voltage sets the maximum DC operating level before the device starts clamping; the 12.35V minimum breakdown and 18.2V maximum clamping at 82.4A peak pulse current define the protection window. Bidirectional single-channel configuration suits AC or bipolar signal lines.
Supplied in a SQ-MELF (C) surface-mount package. The MELF barrel footprint requires careful solder-paste volume control during reflow to avoid tombstoning.
The 'US' suffix typically denotes a surface-mount package (SQ-MELF) versus the through-hole version. The electrical ratings — 1500W peak pulse, 9.9V standoff, 12.35V breakdown, 18.2V clamping — are identical. Verify the package code on your BOM before substituting.
