Bidirectional 85V TVS for general-purpose surge clamping
The SMAJ85CA-13-F: It is designed to clamp transients on 85V nominal rails, with a breakdown voltage of 94.4V minimum and a clamping voltage of 137V at the rated 2.9A peak pulse current (10/1000µs waveform). The 400W peak pulse power rating defines its surge-handling capability for a single event.
Peak pulse power and clamping performance
The 85V reverse standoff voltage means the TVS draws negligible leakage below that rail voltage — it only starts conducting significantly when the transient exceeds the 94.4V breakdown threshold. The DO-214AC SMA package is a widely used footprint for low-profile board-level protection — it reflows with standard lead-free profiles and is compatible with automated pick-and-place assembly.
