EMZ2T2R Equivalent & Substitute Parts Reference

Part Overview

The EMZ2T2R, manufactured by Rohm Semiconductor, is a surface-mount bipolar transistor array with both NPN and PNP transistors, rated at 50V collector-emitter voltage and 150mA maximum collector current. The package type is SOT-563, SOT-666 (EMT6). The device supports a transition frequency of 180MHz/140MHz, a maximum power dissipation of 150mW, and operates at junction temperatures up to 150°C. The product is active with significant inventory and is compliant with ROHS3 and REACH directives.

Identifying alternative models is essential to ensure continuity in manufacturing, address supply chain issues, and enable form-fit-function replacements without impacting end-product electrical or regulatory performance.
