What the 400 W peak pulse rating means for your protection design
The SMAJ8.0A-13: For a given clamping voltage, a higher peak pulse power means the diode can sink a larger transient current without self-destructing.
Package, mounting, and temperature range
Housed in the DO-214AC (SMA) package, this is a surface-mount device intended for reflow soldering. The SMA footprint is a common industry standard — the same pad layout works for other SMA-packaged TVS diodes, so a last-minute BOM swap to a different brand or series does not require a board spin. The wide temperature margin means the leakage current and breakdown voltage shift within datasheet limits across the full range — no derating needed for most applications down to -40°C.
