That 27.6V ceiling is what the downstream semiconductor must survive; the 17V standoff sets the normal operating window with margin above the 12V automotive rail. ## 5 kW peak pulse — sizing for the automotive load-dump pulse The 5000W rating is the 10/1000µs waveform peak — that is the load-dump pulse shape defined in ISO 7637-2 and the test pulse classes automotive OEMs run. A 181A peak pulse current at the clamping voltage confirms the device can absorb and route that surge energy to ground without the clamping voltage rising above the 27.6V abs-max at the protected node. The SMC (DO-214AB) package with its copper tab directly die-attached handles the thermal rise from that energy dump — junction temperature is rated to 150°C. ## AEC-Q101 qualification and automotive temperature margin Bourns flags this part in the Automotive, AEC-Q101, 5.0SMDJ-Q series — the AEC-Q101 discipline covers temperature cycling, HTRB stress, surge life, and humidity robustness that a generic industrial TVS does not. The CA suffix confirms bidirectional polarity — it protects against both positive transients on the line and reverse-polarity events without requiring a separate diode. ## Sourcing posture Surface-mount tape-and-reel packaging aligns with standard automotive BOM reel quantities.","metaTitle":"Bourns 5.0SMDJ17CA-Q TVS Diode, 5kW 17V Bidirectional SMC","metaDescription":"Bourns 5.0SMDJ17CA-Q bidirectional TVS diode, 5kW peak pulse, 17V standoff, 27.6V clamping, AEC-Q101 qualified SMC package.
