MMBD4448HCDW-TP Equivalent & Substitute Parts

Part Overview

The MMBD4448HCDW-TP is a general-purpose diode array manufactured by Micro Commercial Co, configured as a 2 Pair Common Cathode device in a 6-TSSOP (SOT-363) surface mount package. This component is rated for 80 V DC reverse voltage with 250 mA average rectified current per diode and features fast recovery characteristics with a 4 ns reverse recovery time. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or manufacturer availability while maintaining identical electrical and mechanical specifications.
