Space saving dual digital transistor ROHM IMB3AT110 designed for inverter interface and driver applications
Product Overview
The EMB3 / UMB3N / IMB3A series are general-purpose dual digital transistors designed for inverter, interface, and driver applications. These devices offer significant advantages in terms of reduced mounting cost and area by integrating two DTA143T chips into a single package (EMT6, UMT6, or SMT6). The independent transistor elements ensure no interference between them, making them suitable for automated mounting machines.
