No buyer-search keyword sample has been scored against AI’s description of this category yet.
These are the brands AI most associates with this electronics category.
Showing 17 brands AI ranks as component manufacturers. The other 2 of 19 brands AI mentions in this category appear as distributors or category-surface entities (paid evidence layer).
Share is each brand’s portion of AI’s total mentions for this category. Mention counts are cumulative across the consensus panel and tracking weeks. Not normalized for panel turnover or model outages — cross-category comparisons require the evidence layer.
VERIFIED = the brand’s own product catalog lists this category · AI-DISPUTED = AI places it here but its catalog does not · UNCONFIRMED = no own-catalog evidence captured yet. We publish what AI says and whether it checks out — we never fabricate a placement. Click a brand for its full footprint.
Threshold rule, panel breadth, observed week, and the per-brand statistics behind each row — plus the reality checks (vantage alignment, supply geography, buyer vocabulary) that tell you whether AI’s rank for Phototransistors holds up off-screen.
Open the evidence layer →How AI talks about Phototransistors, compared to how OEMs describe it on their own product pages, how buyers search for it, how distributors bucket it, and how aggregators classify it in their taxonomies. Each of those five viewpoints is a vantage. The cosine between each pair of vantages tells you whose vocabulary tracks whose — 1.0 means identical wording, near 0 means they don’t share a vocabulary at all.
Distributor bucket and AI consensus use the most-different vocabulary for this category — cosine 0.80.
