48 V rail protection — where the ratings land
Its 48 V reverse standoff voltage means it will not conduct leakage current under normal 48 V operation, while the 53.3 V minimum breakdown voltage defines the threshold where avalanche conduction starts. At the rated peak pulse current of 8.1 A (10/1000 µs waveform) the clamping voltage reaches 77.4 V maximum, which is the hard limit the protected circuit must survive.
This is a single-channel bidirectional device, meaning it clamps equally in both directions.
The part comes in the standard DO-214AA (SMB) surface-mount package, a widely used footprint compatible with automated assembly. The wide temperature margin also means the device maintains its clamping characteristics across the full military temperature range.
