EMZ1 / UMZ1N / IMZ1A is a dual transistor produced by ROHM. It integrates two chips, 2SA1037AK and 2SC2412K, and is packaged in multiple types such as EMT, UMT, and SMT. It has the advantages of small size, low cost, and easy installation.
The EMZ1, UMZ1N, and IMZ1A are general‑purpose dual transistors offered by ROHM. They are available in NPN and PNP epitaxial planar silicon structures and can be mounted in EMT, UMT, or SMT packages, allowing automatic mounting and reduced cost and area.
