Product Description
Product Overview
The EMB3 / UMB3N / IMB3A series are general-purpose dual digital transistors designed for inverter, interface, and driver applications. These devices integrate two independent DTA143T chips within a compact EMT6, UMT6, or SMT6 package, offering significant advantages in mounting cost and board space reduction. Their independent transistor elements ensure no interference between them, making them ideal for space-constrained designs. These transistors are compatible with automatic mounting machines and are suitable for various electronic equipment.
