The copper pad area under the package sets the thermal resistance — for a 1500W pulse, the board's copper plane acts as the heat sink, so a larger pad reduces junction temperature rise during the transient. No power line protection feature — this is a signal or DC rail clamp, not a mains-side suppressor. ## Sourcing posture and lifecycle For automotive OEMs requiring PPAP-level documentation, the AEC-Q101 qualification package is available from Bourns.","metaTitle":"Bourns 1.5SMC33CA-Q TVS Diode, 1500W, DO-214AB","metaDescription":"Bourns 1.5SMC33CA-Q bidirectional TVS, 1500W peak pulse, 28.2V standoff, AEC-Q101.
