About the ROHM Semiconductor ROHM Semiconductor BAS4 Series series

The ROHM Semiconductor ROHM Semiconductor BAS4 Series series groups 7 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 TO-236-3, SC-59, SOT-23-3, current - reverse leakage @ vr of 10 µA @ 40 V and mounting type of Surface Mount. Variants differ by operating temperature - junction, package and diode configuration, so you can match the exact operating temperature - junction your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current ROHM Semiconductor BAS4 Series variants and discontinued ones from a single page.
