Parametric fit — clamping, breakdown, and temperature range
Breakdown voltage minimum is 24.4V, giving a 2.4V margin above the 22V reverse standoff — tight enough to protect 24V nominal rails without nuisance triggering. The -65°C to 150°C junction temperature range covers cold-start automotive and hot industrial enclosures; the DO-214AA SMB body handles reflow without issue.
Package and mounting — DO-214AA SMB on Tape & Reel
Surface-mount DO-214AA (SMB) package, supplied on Tape & Reel. The SMB footprint is larger than the SMA variant, which helps with thermal dissipation during the 600W pulse. No power line protection built in — this is a unidirectional device for signal or low-voltage DC rail clamping.
