Product details

600 W peak pulse in a DO-214AA footprint

The SMBJ13CA-13: With a 13 V reverse standoff voltage and a 14.4 V minimum breakdown, it clamps transients to 21.5 V at a peak pulse current of 27.9 A — a common choice for protecting 12 V rails on general-purpose boards against ESD and surge events.

Bidirectional clamping for signal and power lines

Power line protection is marked as 'No' — this TVS is intended for low-energy signal or secondary-side rail clamping, not for direct mains or high-energy power bus suppression.

Active production, sourced per RFQ

The base product number SMBJ13 covers the full family; the -13 suffix denotes the Tape & Reel packaging option.

Frequently asked questions

Is SMBJ13CA-13 suitable for 12 V rail protection?

Yes — the 13 V reverse standoff voltage sits above a nominal 12 V rail, and the 14.4 V minimum breakdown provides margin before the TVS starts conducting leakage current. The 600 W peak pulse rating handles typical surge events on secondary-side supplies.
