600W bidirectional TVS for 12V/24V automotive bus protection
The SMBJ33CAQ-13-F: The 33V standoff voltage sits above a 24V nominal rail with margin for load-dump and jump-start transients, while the bidirectional structure protects signal lines that swing both positive and negative relative to ground — common on CAN, LIN, and sensor interfaces in automotive ECUs.
Automotive temperature grade and AEC-Q101 qualification
The base product number SMBJ33 identifies the 33V standoff variant in the SMBJ family; the Q suffix signals automotive qualification, and the CA suffix indicates bidirectional clamping.
Supplied on tape-and-reel (TR) or cut-tape (CT) in the DO-214AA (SMB) package — the standard footprint for 600W TVS diodes in automotive ECUs and body-control modules.
