The -55°C to 150°C junction temperature range covers under-hood and engine-bay environments — the 150°C upper limit leaves margin for self-heating during repetitive surge events. Housed in the DO-214AC (SMA) package, with a surface-mount footprint that matches standard SMA diode land patterns. The supplier device package is SMA — the same body as the generic SMA footprint, so no custom pad geometry is needed. The tape-and-reel packaging suits automated pick-and-place assembly. No power line protection feature — this is a pure transient suppressor, not a filter.","metaTitle":"SMAJ51CAQ-13-F TVS Diode, 400W, 51V, Bidirectional, DO-214AC","metaDescription":"Diodes Incorporated SMAJ51CAQ-13-F bidirectional TVS diode, 400W peak pulse, 51V standoff, AEC-Q101 automotive grade.
