For a 48V nominal automotive bus with transients reaching 90V, this keeps the protected node inside a 100V-rated component's safe operating area. The -55°C to +150°C junction temperature range covers under-hood and engine-bay thermal profiles — the 150°C upper limit gives margin for self-heating during repetitive surge events. ## Package and board-level integration Housed in the DO-214AC (SMA) package — a standard surface-mount footprint shared across the SMAJ family. The supplier device package is SMA, which mates directly with the DO-214AC land pattern. For a 400W TVS, the SMA body's copper pad area under the cathode tab sets the thermal resistance to the board; a 1 oz copper pour of at least 30 mm² per terminal keeps the junction temperature rise within the 150°C limit during a 10/1000µs pulse.","metaTitle":"Diodes SMAJ58AQ-13-F TVS Zener, 400W, AEC-Q101, DO-214AC","metaDescription":"SMAJ58AQ-13-F from Diodes Inc — 400W peak pulse TVS Zener diode, 58V standoff, AEC-Q101 qualified, DO-214AC (SMA) package.
