RF301B2STL Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor RF301B2STL is a 200V, 3A fast recovery surface mount rectifying diode, offered in the TO-252-3, DPAK (2 Leads + Tab), SC-63 package type. The device features a maximum forward voltage of 930 mV at 3 A, reverse recovery time of 25 ns, and a maximum junction temperature of 150°C. The product status is listed as obsolete, making it necessary to identify alternate models with matching or compatible parameters for use in both new and sustaining designs requiring ROHS3 and REACH compliance.
