The -55°C to +150°C junction temperature range covers under-hood and cabin environments without derating concerns. ## Clamping parameters and fit With a 45 V reverse standoff voltage and a minimum breakdown voltage of 50 V, the SMBJ45CAQ-13-F stays transparent below the rail and starts conducting only when the transient exceeds the breakdown threshold. The 72.7 V clamping voltage sets the peak voltage the downstream circuitry sees during a surge event. The DO-214AA (SMB) package is a common footprint; rework is straightforward with standard hot-air tools, and the package outline is clearly marked for orientation. The part is orderable under the listed order code; confirm the BOM position count and the mating half before committing.","metaTitle":"Diodes Inc SMBJ45CAQ-13-F TVS Diode, 600W, Bidirectional","metaDescription":"Diodes Inc SMBJ45CAQ-13-F automotive TVS diode, AEC-Q101, 600W peak pulse, 45V standoff, bidirectional, SMB package.
