RF071MM2STFTR Equivalent & Substitute Parts Reference

Part Overview

The RF071MM2STFTR by Rohm Semiconductor is a surface-mount, general-purpose rectifier diode rated for 200 V reverse voltage and 700 mA average rectified current. This diode features a fast recovery characteristic and an extended junction temperature rating suitable for automotive applications, with AEC-Q101 qualification and full RoHS3 compliance. Its continued “Active” product status denotes ongoing manufacturer support and availability. Identification of strictly parameter-matched alternatives within the SOD-123F package group is important for risk management, dual-sourcing, and assurance of supply chain continuity in design and manufacturing.
