About the Alpha & Omega Semiconductor Inc. AOTS Series

The Alpha & Omega Semiconductor Inc. AOTS Series series groups 2 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. Every variant in the range shares a common case of SC-74, SOT-457, FET type of P-Channel and mounting of Surface Mount. Variants differ by current - continuous drain (Id) @ 25°C, drain to source voltage and drive voltage (Max rds on, min rds on), so you can match the exact current - continuous drain (Id) @ 25°C your application requires using the selection guide below. All listed Alpha & Omega Semiconductor Inc. AOTS Series part numbers are active and orderable.
