Clamping window for a 6.5V supply
The SMAJ6.5A-13-F: The 6.5V reverse standoff voltage is the maximum DC voltage the TVS blocks without conducting — it sits on a 6.5V rail or a 5V rail with margin. Breakdown occurs at 7.22V minimum, and the clamping voltage at peak pulse current is 11.2V maximum. This 4V window from standoff to clamp means a downstream device rated for 12V or higher sees protection before its abs-max is reached. The 400W peak pulse power is the product of clamp voltage and pulse current; it sets the energy-handling ceiling for a given pulse duration.
Temperature range and package integration
The DO-214AC SMA package is a JEDEC-standard footprint — the same pad layout used across the SMAJ family, so a BOM change to a different voltage variant reuses the same PCB land pattern. The part is marked as general-purpose application and does not include power-line protection — it is intended for DC rail and signal-line transient suppression, not AC mains clamping. Mounting is surface-mount with tape-and-reel packaging for automated pick-and-place.
