600W Zener TVS in DO-214AA — transient protection for general-purpose rails
Clamping voltage is 11.4V at a peak pulse current of 52.6A.
Clamping voltage and pulse current — what they mean for rail protection
With a minimum breakdown voltage of 6.67V and a maximum clamping voltage of 11.4V at 52.6A, this device protects 6V rails against transients while staying below the typical 12V absolute maximum of downstream ICs. The 600W peak pulse power rating at 10/1000µs gives a 52.6A surge capability — adequate for suppressing inductive kickback or ESD events on power inputs.
The base product number is SMBJ6.0, and the DO-214AA footprint is industry-standard across multiple TVS families.
