The verdict
Alpha and Omega Semiconductor runs at 4% of its industry's injury rate - far safer than the typical Diodes, solid-state (e.g., germanium, silicon), manufacturing workplace, earning a grade A.
Alpha and Omega Semiconductor: 0.1 TCR = 4% of Diodes, solid-state (e.g., germanium, silicon), manufacturing BLS 3.3 · 4y Form 300A (see methodology below)
Alpha and Omega Semiconductor safety composite
Alpha and Omega Semiconductor scores strongest on total case rate (tcr) (safer than 95% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

Benchmarked live against every credibly-rated employer in the same NAICS industry code in the current OSHA extract (a segment must have at least 8 rated peers to benchmark). Not a legal or compliance determination; PlainSafetyScore's own weighting (TCR 40%, DART 35%, fatalities 25%).
Alpha and Omega Semiconductor held a steady TCR band
Alpha and Omega Semiconductor's TCR held near 0.0 from 0.0 in 2019 to 0.0 in 2022. Peak filing year was 2021 at 0.5 TCR. In 2022, DART was 0× this establishment's average TCR (severity share of cases).
