RF1601NS2DTL Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor RF1601NS2DTL is a diode array designed for general-purpose fast recovery rectification. It features a 1 Pair Common Cathode configuration, rated for 200 V DC reverse voltage and 16A average rectified current per diode. The device is housed in a surface-mount TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package and is ROHS3 compliant. The part status is Active, and current inventory is available. In engineering and production settings, identifying alternative models is necessary for risk management, supply continuity, and qualification flexibility, especially when supporting parallel product lines or responding to allocation issues.

Substitute Part Grouping Explanation

Substitution is determined exclusively by matching the following key electrical and mechanical parameters: Diode Configuration (1 Pair Common Cathode), Maximum DC Reverse Voltage (200 V), Average Rectified Current (per Diode), Forward Voltage (Vf) characteristics, Recovery Speed (Fast Recovery ≤ 500 ns, > 200mA Io), Reverse Recovery Time, Reverse Leakage Current, Maximum Junction Operating Temperature, RoHS compliance, Moisture Sensitivity Level (MSL), mounting type, and package type (TO-263-3, D2PAK, TO-263AB). Only parts that strictly meet these criteria are presented as substitutes.
