600W peak pulse power, 6.5V standoff — Zener TVS for general-purpose clamping
The SMBJ6.5A-13: It clamps transients from a 6.5V reverse standoff rail to a maximum of 11.2V at 53.6A peak pulse current. The 7.22V minimum breakdown voltage ensures the device starts conducting before the protected rail exceeds safe limits, while the 11.2V clamp holds the transient below typical downstream IC absolute maximum ratings.
Package and thermal envelope
The SMB footprint is a common industry standard for 600W-class TVS diodes, allowing direct replacement in existing layouts.
