RF2001NS2DFHTL Equivalent & Substitute Parts Reference

Part Overview

The RF2001NS2DFHTL by Rohm Semiconductor is a high-performance diode array in the diodes, rectifiers category. This device features a 1 Pair Common Cathode configuration, designed for general-purpose rectification up to 200 V reverse voltage and 20 A average forward current per diode. With its surface mount TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package, automotive grade (AEC-Q101), and ROHS3/REACH compliance, the RF2001NS2DFHTL is suitable for automotive and industrial power designs.
Due to supply chain fluctuations or requirements for alternate sourcing, identifying electrical and mechanical equivalent or substitute parts is essential to ensure design continuity.
